The very first generation of the allroad quattro proved to be a great success for Audi. Based on the A6 Avant, the allroad has been the big Audi for any road and season since it was launched in 2000. Now its successor is ready to make its debut. The new A6 allroad quattro is more spacious, luxurious, distinctive and versatile than ever. Plus, of course, it fully lives up to its name by delivering even more dynamic power and handling, both on and off the road.
None of the premium-class competitors on the international stage have anything to rival the Audi A6 allroad quattro, whose independent concept is entirely the work of Audi. It is closely related to the A6 Avant and offers virtually the same level of commanding sporty performance. However, what makes the A6 allroad quattro so special is that it keeps going when the tarmac ends thanks to the off-road components it incorporates into the sporty concept of the Avant. This enables it to neatly bridge the divide between sporty elegance and striking versatility.
Design
The exterior design takes its cue from the expressive design language and lines of the Audi A6 Avant, producing a character steeped in timeless elegance and emotional sportiness. The dynamic contours, the stimulating finish of its surfaces and the almost coupé-like silhouette all help to set the tone, reinforced by the dynamic rise of the strong shoulder line, the low window strip and the gently sloping roof. At the same time, the bold off-road styling elements blend harmoniously into the overall picture.
The underride protector made of stainless steel is just one of these elements. The single-frame grille sports a modified look, with chrome strips adorning the vertical bars and a licence plate that now appears to float in mid-air. Further identifying features include the restyled bumpers and the larger exterior mirrors.
Front fog lights, a headlight washer system and a light and rain sensor are all included as standard. Seen from the side, sturdy door strips, made of aluminium on request, accentuate the dynamic line. The roof rails, also of aluminium, rest on four supports. The sill panelling conveys an impression of tremendous power, as do the flared wheel arches housing 17-inch or 18-inch wheels in three special designs.
At the rear, the A6 allroad quattro can be recognised by an underride protector made of stainless steel and an aluminium-look trim strip. If xenon plus headlights are chosen, an attractive LED unit for the brake and tail lights is incorporated into the rear light clusters.
The interior ambience too, with its fine lines and elegant forms and colours, offers supreme quality and harmonious aesthetics, an initial taste of which is provided by the new aluminium door sill trim. There is a choice of four interior colours which can be combined with six seat fabrics and five inlays.
Body
The new Audi A6 allroad quattro has a length of 4,934 millimetres, a wheelbase of 2,833 mm, a width of 1,862 mm and, depending on the setting of the adaptive air suspension, a height of 1,459 to 1,519 mm. Compared with its predecessor, the length has extended by 124 mm, the wheelbase by 76 mm and the width by 10 mm, enabling the driver and up to four passengers to enjoy lavish levels of spaciousness and seating comfort.
The Audi A6 allroad quattro is available exclusively with the Avant body version. The load area - whose storage capacity can be extended from 565 up to 1,660 litres by folding down the backrests - incorporates two securing rails. A highly versatile range of luggage compartment options, including a load-securing set, is available, as is an automatically opening and closing tailgate. Particularly long items can easily be accommodated thanks to the load-through hatch including ski bag. The standard adaptive air suspension with its integrated self-levelling function ensures a comfortable ride in the A6 allroad quattro.
The body has a composite construction featuring a high proportion of high-strength and ultra-high-strength steel panels, plus lightweight aluminium components which reduce weight primarily at the front end. In the event of an accident, passengers are protected by a network of precisely matched sections. Two front airbags, side airbags in the front (in the rear too as an option) and the sideguard head airbag system are all permanently on standby. Audi backguard reduces the consequences of a rear-end collision.
The interior is distinguished by its exquisite finish and top levels of functionality. At the heart of the operating concept is the MMI terminal, which the driver can use to configure numerous convenience functions that can then be viewed on a monitor. Also on the list of standard equipment is an electromechanical parking brake which offers considerable practical benefits over conventional technology, not least because it opens up greater scope for the design of the centre console.
Drivetrain
The A6 allroad quattro comes with a choice of four powerful, longitudinally installed engines, comprising two petrol and two diesel models. All four are direct-injection units and belong to Audi’s state-of-the-art family of V-engines.
FSI petrol direct injection is a hallmark technology of the Audi brand. Following numerous victories in the Audi R8 Le Mans racing car, it has now been introduced on a broad scale in standard production vehicles too. The 3.2 FSI develops 188 kW (255 bhp). The V6 engine’s maximum torque is 330 Nm, available at 3,250 rpm. The new 4.2 FSI has even more power at the ready. The V8 with direct injection musters up 257 kW (350 bhp) and 440 Nm, the latter being on tap at 3,500 rpm.
Both V6 diesel engines combine superb efficiency with hefty pulling power and refined smoothness. The task of mixture preparation is handled by a latest-generation common rail system which propels the fuel into the combustion chambers at a pressure of up to 1,600 bar. The 2.7 TDI develops 132 kW (180 bhp) and 380 Nm.
Its maximum torque is available from just 1,400 rpm and remains constant up to 3,300 rpm. The 3.0 TDI delivers 450 Nm of torque to the crankshaft between 1,400 and 3,250 rpm, while maximum output has been increased compared to the A6 Avant to 171 kW (233 bhp).
quattro permanent four-wheel drive, featured as standard on all A6 allroad quattro models, has a decisive influence on driving characteristics. Its self-locking centre differential splits the drive torque variably between the front and rear axles. Generally, 50 percent goes to each but, if necessary, up to 75 percent of the power can be directed to either axle. On loose terrain the quattro drive provides excellent traction and on the road it ensures sporty agility, firm grip and maximum driving safety.
Chassis
The chassis of the A6 allroad quattro combines sporty handling with silky smooth comfort. Not only has the wheelbase been increased, the track width at the front is also up by 22 millimetres to 1,596 millimetres and at the rear it has been increased by 2 millimetres to 1,587 millimetres. In addition, weight distribution between the front and rear axles has been optimised. The chassis consists of a highly complex four-link front suspension - built primarily using aluminium components - with a self-tracking trapezoidal-link rear axle. The servotronic power steering, which is standard, provides variable power assistance according to vehicle speed
The electronically controlled adaptive air suspension, also a standard feature, adds another key dimension to the handling abilities. It allows the ride height of the body to be altered in four stages by up to 60 millimetres, both automatically - depending on road speed - and manually via the MMI terminal. The control unit also automatically adjusts the control characteristics of the adaptive shock absorbers to reflect the type of road surface and driving style.
The generous ground clearance of as much as 185 millimetres provides the Audi A6 allroad quattro with additional qualities off the beaten track, for instance on rough gravel roads or snow-covered mountain passes. As an option, 245/45 R 18 all-terrain tyres are available, together with a reinforced engine underguard.
The ESP stabilisation program has been enhanced to include special functions too. In “off-road” mode, for example, ESP intervention is delayed so that forward propulsion can take priority.
Equipment
In Germany, the 3.2 FSI is priced at €50,600, the 2.7 TDI costs €47,600 and the 3.0 TDI €50,600, with the TDI models both including a diesel particulate filter. When the new A6 allroad quattro first goes on sale, the two diesel models will be available immediately with the 6-speed tiptronic automatic transmission, as will the 3.2 FSI. The starting line-up will be joined shortly afterwards by 6-speed manual versions of the V6 petrol model and of the 3.0 TDI and by the 4.2 FSI model with tiptronic.
The Audi A6 allroad quattro comes with an equipment level which befits its premium status. The primary features of the A6 allroad quattro which predestine it for off-road use are the height-adjustable air suspension as standard, the rigid body and the robust off-road specifications such as the underbody guard and special ESP configuration. Active and sporty people will appreciate the versatile rail system in the luggage compartment and the aluminium roof rails. On-board comfort and convenience is ensured by the deluxe automatic air conditioning with separate temperature controls for the driver and front passenger and by the MMI basic operating system.
The 4.2 FSI with its powerful V8 engine runs on 18-inch wheels, housing ventilated front and rear brake discs. Its inlays gleam in Vavona wood assam grey; the inside door trims and seats are covered in leather. The front seats are electrically adjustable. An anti-theft alarm system, the driver information system, deluxe automatic air conditioning plus and a centre armrest at the front complete the luxurious standard equipment of this range-topping model.
The appealing luxury and high-tech extras available for the Audi A6 allroad quattro include the adaptive light dynamic cornering light system, the advanced key keyless access system, and the Audi parking system advanced parking aid - here the MMI monitor shows the image captured by the rear-view camera.
A Bluetooth interface for the telephone is available on request, as is a DVD navigation system, a surround-sound system from BOSE and sports seats.

Exterior design
The new A6 allroad quattro faithfully perpetuates the design evolution of the brand. Its lines blend the light, elegant Audi architecture exemplified by the A6 Avant with new, bold styling elements taken from the off-road segment. Even the basic proportions have a classic flair, with the low window strip and the distinctly coupé-like roofline that slopes down gradually at the rear. The outline of the body is traced by three lines which inject it with a dynamic spirit and that added forward urge.
The shoulder line arches upwards gently from the front wing, before running down the flanks of the body as an eye-catching light-refracting edge and ending at the rear lights. The inverse arch traced by the dynamic line flows out from the bottom of the front bumper. It runs rearwards above the door sill edges and finally wraps round the tail as a bumper edge to outline the body from front to rear.
Finally, the V-bonnet line also originates in the front bumper before continuing over the bonnet and merging into the roofline. It terminates in the upwards-pointing separation edge atop the tailgate, rounding off the sporty silhouette.
The intricate interplay between concave and convex arcs, between positively and negatively curved surfaces, adds a further dimension to the design of the A6 allroad quattro. It emphasises the stimulating interplay of light and shadow which keeps adding new facets to the design as the viewing angle changes.
Single-frame grille: floating licence plate
The special off-road styling elements which make the Audi A6 allroad quattro truly stand out include the stainless steel underride protector beneath the engine that highlights the vehicle’s robust nature with its solid looks. To accommodate the underride protector, the prominent single-frame grille has been slightly reduced in height. The licence plate holder has been reduced in size to the extent that the licence plate now appears to be floating in mid-air. Depending on the market, Audi adapts the size of the holder to match the local licence plate format.
The vertical bars of the grille are trimmed with chromed strips, while the bumpers have also undergone restyling. They are painted in a contrasting matt colour as standard and are available in a body-coloured matt finish as an option. New, flat intake slits beneath the radiator grille direct even greater quantities of air to the engine. Visible behind the clear-glass lenses on either side is the very latest in headlight technology: as an option, the new A6 allroad quattro can be specified with the adaptive light dynamic cornering light system, incorporating high-intensity xenon plus headlight units and daytime running lights.
Powerful touches: 17-inch wheels as standard
When seen side on, the eye is immediately drawn to the striking roof rails which are made from aluminium and rest on four supports. The enlarged heated exterior mirrors, which adjust and retract electrically, provide an extra-wide field of vision. At the bottom of the vehicle’s flanks, the dynamic line is accentuated by sturdy door strips in a contrasting colour, which can be specified in aluminium too on request. Additional sill panelling conveys an impression of tremendous power, as do the flared wheel arches. Both elements are painted in a matt finish, either in a contrasting colour or optionally in the same colour as the body.
Depending on the engine, the wheel arches house wheels measuring 17 or 18 inches in diameter which come in three special designs - a 7-arm rotor design, 10-spoke design and 5-arm “Aero” design. The tyres are slightly larger in diameter than those on the A6 Avant, automatically giving the Audi A6 allroad quattro a higher-set appearance.
The muscular rear end of the Audi A6 allroad quattro can be identified by its wide track and the visible exhaust tailpipes, which are 88 millimetres in diameter on the V8 FSI. An aluminium-look trim strip in the vicinity of the bumper adds a glittering touch, while a stainless steel underride protector also gleams out from underneath the vehicle floor. Like its counterpart at the front end, the rear bumper comes painted in a contrasting matt colour as standard or can be specified in a body-coloured matt finish as an option. If the adaptive light dynamic cornering light system is specified at the front, an attractive LED unit for the brake and tail lights will be incorporated into the rear light clusters.
There is a choice of ten smart paint finishes for the A6 allroad quattro. One of them - Condor Grey - is reserved for the new model and the Audi Q7. In the second half of 2006, Polar Blue will become available as an eleventh colour that will be exclusive to the A6 allroad quattro.
Interior
Supreme sportiness, luxurious comfort and ergonomic perfection are the order of the day for the cockpit in the new Audi A6 allroad quattro. The fine lines and forms together with the colour scheme convey an impression of supreme quality and harmonious aesthetics. The first taste of this is provided by the new aluminium door sill trim inscribed with the “allroad quattro” lettering. The door sill trim comprises three sections, with the blend of highly polished, brushed and matt surfaces producing a fascinating effect.
New two-tone, hard-wearing Fresco carpeting covers the floor inside the A6 allroad quattro. Four interior colours are available to choose from, including the new paranut brown and cardamom beige, which can be combined with six seat fabrics and five inlays.
The sports seats have a two-tone design. The range of inlays includes the familiar Walnut brown, Walnut mid-brown matt finish and Fine grain birch wood beige wood panelling as well as the new standard material, Aluminium Axial, and the new optional inlay Californian Vavona wood assam grey (standard on the top-of-the-range 4.2 FSI). The sports seats are finished in a two-colour look.
Sporty and intuitive: the ergonomics
A joint cover connects the instrument cluster with the upper part of the centre console, which is angled slightly towards the driver, to form a single unit. The high, wide centre console, with controls and switches within perfect reach, emphasises the sporty interior architecture that integrates the driver as the central player. The instrument cluster echoes the styling in the A6, as does the overall cockpit. The instrument cluster distinctive teardrop-shaped surround allows the coolant temperature and fuel gauges to be positioned on the outside next to the rev counter and speedometer dials.
The latest generation of Audi steering wheels from the A6 now make their debut in the new A6 allroad quattro too. The centrepiece of the three and four-spoke steering wheels is the unmistakable form of the trapezoid-shaped grille with the four rings.
The skeleton of the steering wheels is made from diecast magnesium, a material that combines extremely low weight with high strength. As an alternative to the standard leather-wrapped rim, customers can also opt for a fine-wood variant. All versions of the steering wheel can be ordered as an option with multifunction buttons and, on tiptronic models, with shift paddles mounted on the steering wheel. The four-spoke multifunction steering wheel is also available with an optional heated rim.
The electromechanical parking brake fitted in the Audi A8 and A6 was also the engineers’ choice for the Audi A6 allroad quattro. The inclusion of this technology opens up extra styling scope for the design team. Doing away with the conventional handbrake lever permits a more freehanded console and armrest design that results in an extremely practical, ergonomic layout.
Intuitive: the MMI terminal
Positioned behind the gear lever within comfortable reach of the driver’s hand is the operating terminal for the MMI system. This is the user interface with which Audi is now also offering an infotainment platform and operating concept for the new A6 allroad quattro that combine ease of operation with perfect positioning and a consistent inner logic. As confirmed by the numerous tests conducted by the motoring press, the intuitive operation of the MMI system is markedly superior to the solutions used by Audi’s competitors.
MMI in the first instance comprises the terminal in the centre console with a large control button that can be turned and pressed. The softkeys arranged around the control button have specific control functions in the various menus.
On either side of the terminal there are a total of up to eight function keys with which the user can call up the most important main menus directly, as well as the Return key for exiting the menu level. The functions are subdivided logically into four groups: the Entertainment sub-group comprises the RADIO and CD/TV functions, the Communication sub-group is made up of TEL and NAME (address book for telephone numbers and navigation functions). NAV and INFO (for traffic information) form the Information group; CAR and SETUP are the Control group.
The second central MMI component, the MMI display, is located at the top end of the centre console exactly in the driver’s line of vision. The basic screen layout corresponds exactly to the arrangement of the controls on the MMI terminal, permitting an intuitive association between the on-screen display and the driver’s hand movements. The MMI system is available for the A6 allroad quattro in three different configurations: MMI basic (standard), MMI basic plus and the full MMI version.
MMI basic: with radio/CD player
Even in standard guise, the Audi A6 allroad quattro comes with MMI basic, featuring the terminal, a 6.5-inch monochrome display, as well as an integrated radio and single-disc CD player. Music output is via a 2×20 watt amplifier and two-way speakers in the front doors. Even the basic system comes with speed-dependent volume control and excellent radio reception courtesy of the diversity aerial. Furthermore, numerous vehicle functions such as interior light configuration, the deluxe automatic air conditioning and various warning signals can be controlled via the MMI basic terminal. The terminal itself is networked with the vehicle electronics via a high-speed MOST bus, allowing it to take care of a whole series of checking functions.
MMI basic plus: sound system with ten speakers
The audio system can be upgraded to include additional components by opting for the more sophisticated MMI basic plus version. A TP memory function, for example, is able to record traffic announcements lasting up to four minutes. Sound reproduction is the task of an advanced 6-channel sound system incorporating a total of ten speakers (two three-way combination speakers at the front and a pair of two-way combination speakers at the rear).
On top of this, MMI basic plus can also be combined with a CD-based navigation system featuring visual route guidance using arrow pictograms and additional text information displayed directly in the driver’s line of vision in the driver information system. Destinations may be entered directly or, for added convenience, from the MMI address book.
Route planning takes all information on tailbacks and any warnings provided by TMC traffic radio messaging into account.
MMI: colour screen plus CD changer
In the deluxe full-specification version, MMI comes with a 7-inch colour monitor in the new Audi A6 allroad quattro. In addition to the high-quality audio system already featured with MMI basic plus, a double tuner and a six-disc CD changer are also included as standard. A further option available in combination with MMI and MMI basic plus is the surround sound system from US audio specialists BOSE that promises a new dimension in listening pleasure: no fewer than eight amplifier channels distribute the sound around the listener for a true concert-hall experience. The system also adapts dynamically to the vehicle’s background noise levels with the help of the BOSE AudioPilot®, enabling it to provide optimum sound in all situations.
As an option, MMI can be expanded to include a DVD-based navigation system. A DVD provides more than ten times the storage capacity of a conventional CD-ROM. This is enough to fit almost the entire Western European road network on a single disc, meaning that the driver no longer has to change the CD when crossing borders.
The quicker access times also mean that the navigation system calculates the route much more swiftly than CD-based systems. This allows the user to smoothly zoom in and out or quickly move the map in any direction. Destinations and route options are entered in the conventional way via a menu in the MMI. As an alternative, the navigation system can also be operated using the optional speech control system. A TV tuner may also be added on request.
The Audi parking system advanced, a sophisticated visual parking aid which works based on a rear-view camera, is yet another high-tech feature that can be found in the list of optional extras. The ultra-light-sensitive camera is integrated into the tailgate’s handle and has a wide angle of coverage of up to 130 degrees. Its rectified image appears in the MMI display.
When reverse parking, the system indicates the correct course to take dynamically using various guidance lines and fields. In the case of parallel parking, for instance, the areas highlighted in blue indicate the space required by the A6 allroad quattro. Blue lines show the driver when to apply full lock and counter-lock. When a perpendicular parking manoeuvre is called for, orange lines indicate the correct course. The camera’s image also shows the rear bumper and a trailer hitch, if fitted, allowing the vehicle to be guided beneath a trailer drawbar with pinpoint precision.
Discreet and powerful: the deluxe automatic air conditioning system
The Audi A6 allroad quattro comes as standard with deluxe automatic air conditioning featuring a recirculation and pollen filter as well as a sun sensor. Temperatures may be set separately for the driver and front passenger, and there are air vents on the back of the centre tunnel for passengers in the rear.
Even greater comfort and well-being is available by opting for the deluxe automatic air conditioning plus system (standard on the 4.2 FSI). This system uses a temperature sensor that can gauge the position of the sun, an air quality sensor and a humidity sensor to analyse the specific climatic conditions inside the car. The centre vent comes with separate temperature control allowing, for example, warm air to be directed at the side windows through the side vents to prevent them from misting over and cool air to be supplied at head level through the centre vent. Perforated grilles at the top of the dashboard allow the occupants to enjoy practically draught-free ventilation. and there are additional ventilation louvres in the B-pillars for the rear.
Intelligent links: the telephone systems
The new Audi A6 allroad quattro can be fitted with either the necessary preparation for a mobile phone or a built-in phone with Bluetooth technology. Customers selecting the mobile phone solution can connect their phone using an adapter or wirelessly by means of Bluetooth technology. The adapters have intelligent charging electronics and an interface to the outside aerial and are integrated neatly and practically into the storage compartment in the centre armrest.
Regardless of how the mobile phone is connected, all functions can be operated via the MMI controls. The TEL key provides access to the operating menu as well as to the phone book. Drivers can also operate the most important telephone functions using the buttons on the optionally available multifunction steering wheel, without having to even take their hands off the wheel.
The Bluetooth car phone - a brand new product
The universal Bluetooth hands-free unit will be complemented by a brand new product: the Audi Bluetooth car phone. This innovative phone solution offers an unprecedented level of convenience as it will allow drivers to simply leave their mobile phone in their jacket pocket. It will no longer be necessary to insert the mobile phone into an adapter set.
The Audi Bluetooth car phone solution shuts down the GSM stage of the mobile phone completely, so that the mobile phone serves merely as a mobile SIM card reader. No TWIN card or constant juggling of SIM cards, as with a conventional built-in phone, is necessary. The data for authenticating the user is transmitted via Bluetooth in a secure, encrypted form.
The control unit built into the vehicle contains an integral GSM module that establishes an optimum radio connection with the phone network via the vehicle’s exterior aerial. The key advantage of this is that the mobile phone no longer radiates any transmission energy inside the car; in other words, a connection to the external aerial is no longer needed on the mobile phone.
As a further option, a wireless Bluetooth handset can be connected in conjunction with the Audi Bluetooth car phone which has been specially designed to cater to the needs of passengers in the front or rear who want to conduct confidential phone calls. This handset has been custom-developed in line with Audi requirements. It offers an ergonomic user interface that is specially matched to the vehicle, as well as outstanding acoustics.
In addition to the Audi A6 allroad quattro, the Audi Bluetooth car phone will also be made available for the Audi A6, the Audi A8 and the Audi Q7.
Extra convenience: light and rain sensor
All new Audi A6 allroad quattro models come as standard with a combined light and rain sensor which automatically activates or deactivates the low-beam headlights and the windscreen wipers as and when required. The system’s sensor technology is discreetly integrated into the bracket of the interior mirror at the top of the windscreen where it does not in any way obstruct the driver’s field of view.
Two light sensors operating independently of one another determine both ambient brightness and light conditions in the direction of travel. Taking this information as well as the speed of the car into account, a microprocessor permanently calculates whether it is necessary to switch on the low-beam headlights. The system is activated by turning the rotary light switch to the “Auto” position. Another standard feature of the light sensor is the coming home/leaving home function. Whenever the doors are unlocked with the radio remote control in the dark, the car’s exterior and interior lights are switched on.
The rain sensor determines the degree of moisture on the windscreen and regulates the wiper speed accordingly. Again, controlling the system is a very easy process: the driver simply has to move the wiper stalk on the steering column to the intermittent position.
Perfect ergonomics: the seats
All occupants of the new A6 allroad quattro benefit from the considerable increase in interior spaciousness which stems from the extension of the wheelbase by 76 millimetres to a length of 2,833 millimetres. This translates primarily into extra room and safety for the legs of the occupants in the front, but there is an additional 10 mm of knee room for passengers in the rear too.
Shoulder room is likewise up by 23 millimetres at the front and 6 millimetres at the rear. The distance between the seat centre-points - a crucial indicator of the occupants’ freedom of movement to the side - has grown by 40 millimetres at the front and 20 in the rear.
The standard seats in the new Audi A6 allroad quattro offer superior comfort over long distances and excellent lateral support for a sporting style of driving. Both driver and front passenger are able to adjust their seat’s height. Alternatively, sports seats can be specified which are powerfully contoured to offer even more support at the sides. Multi-way power adjustment is available as an option which allows the fore-and-aft position, the height, the seat inclination and backrest angle as well as the lumbar support to be adjusted electrically.
The standard seat fabrics combine cloth and leatherette elements. There is also the option of three different leather upholsteries: Milano (standard on the 4.2 FSI, as is leather door trim and electrical seat adjustment), Valcona and natural leather. The sports seats are covered in a combination of Alcantara and leather; the two-colour sports seats in Valcona leather have a two-tone design.
A key-operated switch in the glove compartment can be specified as an option. This switch is used to disable the front passenger airbag, allowing a child seat to be secured to the front passenger seat. This option also includes electric childproof locks for the rear doors and ISOFIX child seat mountings.
Body
Despite its imposing dimensions, the new Audi A6 allroad quattro is nevertheless significantly smaller than the Audi Q7 performance SUV. It measures 4,934 millimetres long, 1,862 mm wide and, depending on the setting of the standard adaptive air suspension, between 1,459 and 1,519 mm high.
Compared with its predecessor, the new model is noticeably larger, with an extra 124 mm of length and 10 mm of width. The new A6 allroad quattro is available exclusively in Avant guise.
Torsional rigidity has been boosted by over 34 percent - an increase that bears clear testimony to the diligent work carried out by the Audi engineers. This extra strength makes its presence felt in terms of both superior vibration comfort and driving dynamics. The minimised vibration amplitudes are one of the key factors behind the excellent interior acoustics of the new A6 allroad quattro.
Lightweight construction: the fine art of sheet metal engineering
The systematic use of high-strength and ultra-high-strength sheet steel has made it possible to reinforce the structural components that are essential for ensuring a high level of stability. The inclusion of lightweight aluminium components such as panels and extruded profiles, on the other hand, has helped to save a considerable amount of weight. The A6 allroad quattro 3.2 FSI, for example, tips the scales at just 1,760 kilograms.
As on the predecessor, sheet aluminium proved to be the ideal material for the bonnet and front wings. Aluminium can also be used, however, on structural components that are subject to only moderate loads, such as the front panel of the radiator tank. The extruded aluminium profiles that have been added to the side sills help to reinforce the passenger cell.
The front roof frame has a hybrid structure, made from a combination of steel and plastic.
Tailored blanks, which are plates with varying wall thickness, or the closely related tailored rolled blanks are used at points subject to particularly high loads, such as the suspension strut cross-members or the front longitudinal members.
The various components are connected to one another using a range of different techniques: apart from conventional spot welding, rivets, spot welding combined with bonding, laser welding and soldering as well as MIG welding help to produce a lasting, solid connection. Each technology corresponds to the exact requirements at the point it is used.
The backbone of a sound safety concept: a rigid passenger cell
One of Audi’s fundamental objectives in developing every model is to make the passenger cell extremely rigid. After all, this is the basic structure serving as the foundation for all of the car’s restraint systems and their protective effect.
One of the most important aspects to consider when designing this cell is behaviour in a frontal impact, as this is by far the most common type of impact in accident statistics.
This presents the body development engineers with two main tasks: first, to convert kinetic energy into deformation energy absorbed by body components and secondly, to ensure that this energy does not even reach the passenger cell, which must be made as robust as possible.
In a frontal crash, intelligent up-front sensors behind the radiator grille interact with other sensors and control units, before alerting the central control unit that the car has been involved in an impact within just a few thousandths of a second. The belt tensioners are then ignited just a few milliseconds later in order to minimise any possible belt slack. Once the loads acting on the belts have reached a certain limit, a belt force limiter feeds out additional belt length, allowing the occupants to “fall” into the airbag once it has inflated.
The full-size front airbags are activated in two stages: in the first stage - activated in low-speed impacts - the forces acting on the occupants are kept at a low level.
At higher speeds, the second stage is triggered in order to utilise the full safety potential of the front airbags.
The particular position chosen for numerous elements, such as the air conditioning, control units, the ignition lock and key, is also an integral part of the car’s safety concept. All hard components have been moved away from critical impact areas where they might harm the occupants; other areas such as the footwells are cushioned by extensive padding.
The safety steering column comes with a double telescoping function, in other words it is - like the pedals - isolated from any intrusions from the front end of the car. A force limiter at the steering column mounting additionally ensures that the steering column will yield in response to impact with the driver’s chest, causing the steering wheel to move down to prevent injury.
In a frontal crash at low speed, there is no need for the airbags to be triggered. In such cases, all of the energy is absorbed by the bumper system, avoiding the need for expensive repairs to the welded body structure behind. Thanks to the precise deformation of the bumper, even the wings remain unharmed in a head-on collision at 15 km/h. Clearly, these are features that insurance companies welcome and duly reward with a particularly favourable insurance premium.
Rapid response units: protection in a side impact too
Unlike the front end of the car, there is only minimal deformation travel available at the side for absorbing energy. Only a particularly high degree of strength in this area can protect the occupants: this is precisely why the flanks of the new Audi A6 allroad quattro have a high-strength structure made primarily from dual-phase steels which offer outstanding rigidity and protection against excessive loads.
In the side sill, an extruded aluminium profile ensures effective absorption of energy. Within the doors, tailored blank inner panels combine with reinforcements at lower window edge and sill level plus an aluminium impact beam to offer substantial resistance to deformation.
Several beams arranged perpendicular to the direction of travel likewise serve to stabilise the passenger cell, while two high-strength steel pipes also installed laterally in the front seats help to keep the occupants’ survival space intact. High-strength reinforcements extending far into the roof area serve to protect the occupants if the vehicle rolls over.
In a collision from the side, the occupants are protected by side airbags fitted as standard at the front (optionally available at the rear) and the head airbag system known as sideguard. The latter covers almost the entire side window area. Hybrid gas generators inflate the airbags in an instant and the pressure is furthermore maintained for a longer period, ensuring that there are still sufficient safety reserves to protect the occupants in the event of a second, subsequent collision.
The new Audi A6 allroad quattro is also extremely well protected against the consequences of collisions from the rear. The cell is built to withstand an impact against a deformable barrier with 70 percent overlap up to a speed of 80 km/h. In such a collision, the fuel tank also remains outside the actual deformation area courtesy of the rear structure of the car consisting of powerfully proportioned members which absorb all of the impact energy.
Aerodynamics: deft design makes up for larger frontal area
More interior space, a wider track: the new Audi A6 allroad quattro is significantly larger than its predecessor. Since the extra width also means a larger frontal area, the aerodynamics engineers were faced with the task of compensating for this fundamental drawback by adopting a particularly elaborate design for the car’s outer skin. Once again, Audi showed itself to be fully up to this task, as testified by the drag coefficient (Cd) of just 0.33 for the new Audi A6 allroad quattro 3.2 FSI. The product of drag coefficient and frontal area is slightly improved in the new model.
One feature that is particularly important in terms of aerodynamics is the underbody panelling. At the front end, the underride protector together with the encapsulation of the engine compartment and transmission ensures a swirl-free flow of air to the central floor area, while wheel spoilers reduce flow losses around the front wheels.
Large cover panels conduct the flow of air along the transmission tunnel all the way back to the rear wheels where it is channelled by the rear underride protector and directed behind the vehicle.
Minimising the uplift at the rear axle is of decisive importance for vehicle handling and stability. The aerodynamic engineers at Audi have developed a separation edge at the top of the tailgate which blends elegantly into the overall design of the rear end. This separation edge significantly reduces the uplift occurring at the rear at motorway speeds.
When travelling at higher speeds, it is the airstream which dominates the overall spectrum of driving noises - just below the recommended autobahn speed of 130 km/h, the air is already flowing around the car at hurricane-like speeds. In the new A6 allroad quattro the acoustic experts at Audi have succeeded in effectively muting the frequency range between 1,000 and 8,000 hertz, as noise in this range is particularly irritating to the human ear.
A triple seal system has been incorporated into the doors to soundproof all of the apertures where sound could enter. When the windscreen wipers are not operating they drop down into a recessed rest position to avoid creating any extra wind noise.
Even when they are in action, the windscreen wipers make surprisingly little noise - this is the result of the new flat wiper technology with its ingenious air routing and of the blades with their integral spoilers.
Permanent safety: adaptive headlights and daytime running lights
Customers may opt to have the very latest in lighting technology fitted behind the clear-glass covers of the A6 allroad quattro headlights, in the form of a single unit that combines xenon plus technology, the dynamic technology of adaptive light plus permanent daytime running lights.
The new A6 allroad quattro comes with light units in Audi’s characteristic “tube” look too.
Featuring anthracite-coloured trims, the tubes for high and low beam appear to almost hover freely in the air, giving the front-end design of the car its very own touch of high-tech. A headlight washer system and fog lights in the front apron are included as standard on all models.
There is a choice of three different headlight versions: standard halogen headlights in free-form technology, xenon plus headlights and xenon plus with the dynamic adaptive light system. With this last top-of-the-range variant, the ellipsoidal module for the high-beam and low-beam headlights pivots in synchronisation with the line of the road or a bend at speeds between approximately 10 and 110 km/h. This greatly improves illumination of the road in front of the vehicle and to the sides. System control takes a range of parameters into account including vehicle speed, steering angle and yaw rate.
Extremely economical: daytime running lights
The significant boost to safety offered by permanent operation of the headlights throughout the day was previously associated with increased energy consumption, with an extra 0.2 litres of fuel being burned every 100 kilometres. It is this drawback that has prevented the wide-scale introduction of this technology in Europe. Yet there is evidence to show that daytime running lights help to enhance driving safety, particularly when the sun is low in the sky.
With the low and high beams in the xenon plus headlights being integrated into the same - the outer - unit, the inner reflector remains free for the use of daytime running lights. A dimmed bulb serves as the source of light, while the other lights are switched off. The resulting increase in fuel consumption is negligible.
Extra-fast: LED rear lights
An attractive LED unit for the brake and tail lights is fitted in the rear lights of the new A6 allroad quattro in conjunction with xenon plus headlights. As well as a long operating life of at least 10,000 hours and a cut in energy consumption of up to 80 percent, the main advantage of this technology is its much shorter response time.
Whereas conventional bulbs take around 200 milliseconds to reach their full brightness, LEDs achieve their full output in less than one millisecond. Drivers following behind will thus recognise much more quickly that the brake lights have come on, giving them more time to react. The emergency stop warning function included as standard is another safety-enhancing feature: if the driver applies the brakes sharply, the hazard warning lights are automatically activated for a certain period to warn drivers behind.
The LED units also add a striking, sporty touch at the rear of the car - the distinctive design of the rear lights gives the tail an unmistakable appearance, with their elegant, sweeping arrangement producing a wide, flat look.
Sporty and versatile: the luggage compartment
The new Audi A6 allroad quattro is geared towards sporty and active customers, and its spacious, highly versatile luggage compartment has been designed with precisely such people in mind. Even the basic configuration offers 565 litres of load space and this can be extended to 1,660 litres by folding down the asymmetrically split backrests - which can be done without having to remove the head restraints. Compared to the outgoing model, these dimensions represent significant increases of 110 and 70 l respectively.
Nothing less than the high quality of the materials in the luggage compartment and its lavish finish would be good enough for Audi. Countless meticulously thought-out details set a new benchmark for this class by virtue of their tremendous versatility. Both the net partition and its housing have been designed for straightforward attachment. The net’s housing is separate from the retracting luggage cover, with both components having a lightweight, slimline construction.
All new A6 allroad quattro models have two securing rails recessed into the floor of the level, 1.05-metre wide load area, plus a total of four fastening rings. The elegantly styled, solid rings can be slid along the rails and locked into position, allowing all manner of luggage items to be safely secured in place if required. Two bag hooks as well as an additional stowage net on one side are also included. A lockable side compartment can be supplied as an optional extra, for keeping objects hidden from prying eyes.
The load floor can be folded up as a standard feature and can be locked in a variety of positions to divide up the load area. Not only does this provide scope for stowing smaller objects in a manner that prevents them from sliding around, it also provides access to the lower stowage area, where a large plastic tray can be found. This tray is ideal for dirty hiking boots after a hike in the mountains or wet snowboard boots after a day on the slopes.
For sports enthusiasts: ingenious options
A number of options are available to A6 allroad quattro customers for enhancing the rail system’s versatility yet further. Take the telescopic bar, for instance, which can be engaged in the two rails to divide up the luggage compartment. Additional support can be provided by a retaining strap, which also clicks into place to either securely lash objects against the sides of the luggage compartment or divide up the load space crossways. Then there is the cycle rack system which provides a neat solution for transporting two mountain bikes securely.
The large storage box for the luggage compartment is a particularly versatile item. It can be secured to the rails in two different positions: with its opening facing to the rear, it can be used for storing smaller items of luggage and for dividing up the luggage compartment.
When pushed up flush against the rear seat with its opening facing forwards, the box can be accessed via the load-through hatch in the rear seat, and is thus transformed into an extra storage compartment that is safely out of sight from inquisitive eyes.
The optional reversible mat has an exclusive velour finish in the interior colour on one side; when turned over, its rubberised, easy-to-clean surface protects the load area floor. The reversible mat also incorporates a fold-out section that can be pulled down over the bumper. This protects the bumper during loading and unloading, or provides a clean surface for sitting down on, when changing your footwear after a hike, for example.
The removable ski and snowboard bag is another new feature that will be of particular interest to winter sports enthusiasts. Winter sports equipment can be packed away swiftly in the bag outside the car, then stowed inside without the interior becoming dirty or even wet.
The tailgate is released by means of an electrically controlled catch as standard, with a hydraulic drive available on request. With this option fitted, the tailgate can be closed by merely pressing a button on its edge; opening can be initiated at the push of a switch in the driver’s door or by pressing a button on the remote control key. The tailgate can be programmed to open to any angle up to the maximum opening angle.
The aluminium roof rails with their smart twin-armed supports serve as the solid basis for a wide range of carrier systems, allowing cycles, skis or luggage boxes to be transported on the roof. The maximum permissible roof load is 100 kg, some 25 kg more than is generally the case.
The A6 allroad quattro is a multitalented vehicle that is perfect for sports enthusiasts. Its air suspension doubles as a self-levelling device, enabling a high payload of 630 kg for all engine variants. The braked trailer load is likewise very high - as much as 2.1 tonnes, depending on the engine. In conjunction with the optional swivelling trailer hitch, a special trailer function is added to the ESP stabilisation program.
Drivetrain
A total of four power units are available for the new A6 allroad quattro - two petrol and two TDI engines, each installed longitudinally. High reserves of power and muscular torque are common to all four engines, which stem from Audi’s state-of-the-art family of V-engines. These are designed around a cylinder angle of 90 degrees and cylinder spacing of 90 millimetres for an extremely compact basic layout. Further characteristics shared by the four powerplants include the maintenance-free chain drive for the camshafts and the low-friction valve gear using roller-type cam followers.
Continuous adjustment of all four camshafts and a variable intake manifold optimise mixture preparation in the two petrol engines - both of these techniques pave the way for high power combined with beefy torque. The cylinder blocks are made from light alloys, ensuring that both petrol units are amongst the lightest on the market - a key advantage which directly benefits the overall weight of the Audi A6 allroad quattro and its axle load distribution.
- 4.2 V8 FSI developing 257 kW (350 bhp), 440 Nm
- 3.2 V6 FSI developing 188 kW (255 bhp), 330 Nm
- 3.0 V6 TDI developing 171 kW (233 bhp), 450 Nm
- 2.7 V6 TDI developing 132 kW (180 bhp), 380 Nm
FSI: high-powered petrol direct injection
The name FSI denotes Audi’s petrol direct injection technology where, in contrast to the conventional system of injecting fuel into the intake manifold, the fuel is injected directly into the combustion chambers. The superior thermodynamics of this method enhance the engine’s overall efficiency.
FSI engines develop more power and dynamism than conventional units with indirect manifold injection - and they do so whilst achieving a very high standard of fuel economy at the same time. By boosting efficiency in this way, Audi has once again demonstrated the brand’s proverbial “Vorsprung durch Technik”.
In June 2001, Audi’s direct petrol injection technology confirmed its tremendous potential in what must be the most challenging endurance test in the world when an FSI power unit propelled the Audi R8 prototype sports car to an impressive overall victory in the Le Mans 24 Hours. This success was followed by numerous further victories over the next four years.
The FSI engines from Audi combine petrol direct injection with a newly developed, demand-controlled single-piston high-pressure pump for each bank of cylinders. This pump feeds exactly the right quantity of fuel into the system to attain the operating pressure of between 30 and 100 bar in the common rail. In the intake tract, which includes the two-stage variable intake manifold, charge motion flaps swirl the air intake to produce a fast, tumbling motion.
In this way a homogeneous fuel-air mixture with a lambda ratio of one is formed in the combustion chambers. Injecting the fuel directly also has the effect of cooling the chambers, thereby reducing the tendency to knock. This gave the development team sufficient scope to raise the basic compression ratio to 12.5:1 in both V engines, compared to a ratio of around 10.5:1 for indirect-injection engines.
The result is a more efficient combustion process resulting in higher power delivery, that translates first and foremost into more spontaneous response. The FSI units demonstrate another of their fortes in the frequently used partial throttle range where they burn less fuel than an indirect-injection engine.
350 bhp: the 4.2 FSI
With a capacity of 4,163 cc, the V8 FSI power unit that is now making its debut in the A6 range is derived from the engine in the Audi Q7 and is also a close relation of the powerplant which can be found under the bonnet of the mighty Audi RS 4. The reduction in the maximum rev speed means that the version in the A6 allroad quattro delivers 257 kW/350 bhp at 6,800 rpm. Torque, on the other hand, is even more abundant than in the RS 4, peaking at 440 Nm at 3,500 rpm. 85 percent of maximum torque is on tap as low down as 2,000 rpm.
The V8 engine’s cylinder block is based on a bedplate structure, where all of the crankshaft bearings are held together in a subframe for extra reinforcement. The crankcase is cast from an aluminium/silicon alloy, with the pistons sliding along the hard silicon crystals inside the cylinder liners. There is no need to insert separate liners allowing the use of bore bridges that are just 5.5 mm wide, a low overall weight and an overall length of just 464 mm.
The four camshafts are driven by a low maintenance double-stage chain drive consisting of three simplex roller chains. It is fitted in a space-saving location on the rear face of the engine, reducing the overall length by a whole 52 mm. A fourth chain drives the ancillaries.
The V8 power unit features a two-stage variable intake manifold made of magnesium. Two high-pressure pumps driven by the intake camshafts feed the petrol to two interconnected stainless steel rails. The petrol is then injected directly into the combustion chambers via the injector valves. The entire process is managed by a single control unit from Bosch - the Motronic MED 9.1.1, one of the most sophisticated units on the international market.
The prodigious power reserves of the V8 FSI unit bestow the new Audi A6 allroad quattro with performance on a par with a sports car. The sprint from standstill to 100 km/h is over in a fleeting 6.3 seconds; top speed is limited to 250 km/h. The sublime V8 is available exclusively in conjunction with tiptronic.
Thanks to the super-efficient FSI technology, consumption is just 11.2 litres of Super Plus per 100 km; the V8 will also run on premium unleaded petrol, albeit with a slight loss of power. It goes without saying that the V8 FSI engine meets the EU4 emissions standard. Two close-coupled multi-stage catalytic converters are integrated into the exhaust system in a compact manifold/catalytic converter module. Tubular sheet-metal manifolds with air-gap insulation are designed for extra-fast activation of the catalytic converters, ensuring that exhaust emission control starts as quickly as possible after the engine has been switched on.
Compact lightweight: the 3.2 FSI
The 3.2 FSI boasts all the same credentials of an ultra-modern engine that can be found in the V8. And, just like its larger sibling, it too has been designed for maximum space efficiency. Measuring only 360 mm in length and 430 mm in width, and weighing a mere 169.5 kg thanks to its aluminium construction, the engine offers tangible benefits in terms of handling characteristics. The cylinder bore of 84.5 mm and stroke of 92.8 mm - precisely the same dimensions as on the V8 FSI - add up to an overall engine capacity of 3,123 cc.
Fine-tuning of the exhaust system produces a distinctly sporty, classic V6 sound that is never intrusive however, making the qualities of the engine a truly sensory experience for the driver. The V6 power unit offers instantaneous throttle response and races all the way up to the red line at 7,200 rpm with consummate ease.
The 3.2 FSI delivers its maximum output of 188 kW (255 bhp) at 6,500 rpm; its peak torque of 330 Nm is available at just 3,250 rpm. Over 90 percent of the engine’s maximum torque is continuously available across a wide rev range from 2,400 to 5,500 rpm - an unprecedented characteristic for a naturally aspirated V6.
Partnered by the 6-speed manual gearbox, the V6 power unit catapults the A6 allroad quattro to 100 km/h in 7.2 seconds and on to a top speed of 242 km/h. Average fuel consumption is 11.0 litres of premium-grade fuel per 100 km, providing yet further evidence of the capabilities of the FSI technology. The corresponding figures for the 6-speed tiptronic transmission are 7.7 seconds, 240 km/h and also 11.0 litres per 100 km.
TDI: high-tech diesel power
Two V6 diesel engines with displacements of 3.0 and 2.7 litres which made their debut in the A6 will be available for the new A6 allroad quattro, too. The two engines both use four valves per cylinder and are part of Audi’s new V-generation line-up. Featuring a chain drive for the camshaft and oil pump, they boast extremely compact dimensions.
The engines measure just 444 mm in length, while the 3.0 TDI unit weighs in at a mere 219 kg, making it one of the lightest diesel engines in its class. This is largely down to the use of an ultra-high-tech material for the cylinder blocks: high-strength vermicular-graphite cast iron.
To ensure an optimum throughput of air, the turbochargers in the two V6 diesel power units work on the principle of variable turbine geometry. Mixture preparation is the task of a latest-generation common-rail system, featuring a high-pressure pump and a rail for each bank of cylinders. The high injection pressure of as much as 1,600 bar results in even finer atomisation of the fuel, meaning superior mixture preparation and more efficient combustion.
Lightweight design close up: the injector needle weighs 4 grams
The piezo inline injectors are undoubtedly the most important innovation of the new common rail system, however. They make use of the piezo effect where an electric voltage is applied to ceramic, altering its crystal structures. The result is a minimal expansion which is transmitted to the injector needle inline. The moving mass at the injector needle has been reduced from 16 to 4 grams. This enables considerably smaller and more precisely metered injection quantities.
The number of injection processes per power stroke can be varied and optimised almost at will thanks to the piezo injectors. Audi’s TDI development engineers opted for up to five injection processes for the 3.0 V6: in addition to the main injection process, double pilot injection takes place at the lower end of the engine speed range and single pilot injection at medium engine speeds. On top of this, single post-injection also takes place up to around 2,500 rpm at partial throttle.
This strategy produces both lower emissions and a smoother combustion process, which in turn benefits the engine acoustics significantly - both TDI units offer class-beating smoothness. At the same time, multipoint injection cuts exhaust emissions. Plus, a portion of the exhaust gases are recirculated and reused for the combustion process, having first been cooled, with the express aim of reducing nitrogenous emissions.
450 Nm: the 3.0 TDI
A veritable powerhouse is available for the A6 allroad quattro in the guise of the 3.0 TDI. Delivering 171 kW/233 bhp at 4,000 rpm and 450 Nm, this diesel unit is able to call upon vast reserves of output and torque from its capacity of 2,967 cc. Maximum torque is available from a mere 1,400 rpm, giving the driver phenomenal pulling power throughout the rev range.
For optimum charging of the cylinder under all operating conditions, the engine has a turbocharger which is accommodated inside the “vee” to make the best use of the available space. Two intercoolers running in parallel reduce the temperature of the intake air drastically, further optimising cylinder charging. The high-speed glow plugs in the combustion chambers are designed to operate in extreme cold, heating up to a temperature of 1,000 degrees within the space of just two seconds.
The exhaust gas is purified by a close-coupled preliminary catalytic converter - located close to the turbocharger - and the main underfloor converter. As a result of all these measures, the A6 allroad quattro 3.0 TDI comfortably undercuts the limits imposed by the EU4 emissions standard. As on the 2.7 TDI, a diesel particulate filter is included as standard in Germany.
The Audi A6 allroad quattro 3.0 TDI is available with a choice of a 6-speed manual gearbox and the 6-speed tiptronic transmission. It covers the standard 0 100 km/h sprint in just 7.5 seconds (with tiptronic 7.8 s); top speed is 231 km/h (with tiptronic 230 km/h). The mighty diesel exercises extreme restraint when it comes to its fuel consumption however, requiring just 8.4 litres per 100 km (tiptronic: 8.8 l).
Powerful and economical: the 2.7 TDI
Fun yet economical, refined and ecological: the 2.7 TDI is an extremely gifted all-round talent. It also lists high output and abundant torque amongst its strengths, and combines them with excellent fuel efficiency.
Reducing the stroke by 8.3 mm to 83.1 mm whilst leaving the bore unchanged at 83.0 mm results in an overall swept volume of 2,698 cc. The vital performance statistics read as follows: an output of 132 kW (180 bhp) across an engine speed range of 3,300 to 4,250 rpm and a peak torque of 380 Nm available from just 1,400 rpm all the way up to 3,300 rpm - as far as the driver is concerned, this translates into remarkable power in virtually any situation. The highly refined acoustics are just another of the 2.7 TDI’s many virtues.
The time of just 9.3 seconds for the sprint from standstill to 100 km/h testifies to the dynamism of the 2.7-litre diesel model; the fuel consumption figure of 8.7 litres per 100 km bears witness to its fuel efficiency. The 2.7 TDI engine is coupled with the silky smooth 6-speed tiptronic transmission.
A model of precision: the transmission
The manual versions of the new Audi A6 allroad quattro - the 3.2 FSI and the 3.0 TDI - come with the ML generation of transmissions, the initials ML identifying them as “manual/longitudinal”. This transmission with its sporty, close ratios offers short, crisp and supremely smooth gearshifts. A special mount for the selector forks effectively isolates the gear lever from driveline vibrations, while a raft of further measures raise overall efficiency by reducing internal friction.
The 6-speed tiptronic automatic transmission is available for all of the engines in the Audi A6 allroad quattro range, and is even fitted as standard on the 2.7 V6 TDI and 4.2 V8 FSI models. This transmission converts the engines’ power potential into a matchless blend of dynamic performance and delightful ease of use. Compared with its five-speed predecessor, the new six-speed transmission is 8 kilograms lighter with an overall weight of just 120 kilograms.
Again compared with the previous five-speed automatic transmission, the gear ratio spread has widened by 22 percent. This means sharper acceleration in the lower gears as well as a clear reduction in engine speed, and consequently a reduction in both noise level and fuel consumption, at high speeds.
The tiptronic control bears the name DSP (dynamic shift program). The lightning-fast gear changes and flexible gearshift strategy add sporting flair, as does the double-declutching initiated by the engine management during downshifts. With the selector lever in position D and when the S sport program is engaged, the electronics are programmed to respond to parameters such as lateral and longitudinal acceleration as well as to movement of the accelerator pedal. This helps to prevent any unwanted upshifts when cornering.
Permanently a step ahead: quattro four-wheel drive
The quattro permanent four-wheel drive system, a standard feature common to all of the A6 allroad quattro models, is the very technology that has secured Audi its decisive status as technological leader for over quarter of a century now. quattro transforms the motoring experience, ensuring sure-footed traction and cornering and serving as a solid basis for dynamic handling and an extremely high degree of directional stability in all weathers.
At the heart of the quattro four-wheel drive in the new A6 allroad quattro is once again a self-locking centre differential. Operation of the differential is purely mechanical, meaning response is instantaneous. Its locking action is only prompted when the throttle is open; differences in rotational speed are tolerated when the brakes are applied and when cornering. Power is generally split 50:50 between the front and rear axles but, if necessary, up to 75 per cent of drive torque can be diverted to either axle.
Chassis
The chassis of the new A6 allroad quattro relies on technology which has already proven its sporting prowess: the advanced four-link front suspension so typical of Audi partnered by the self-tracking trapezoidal-link rear suspension adopted from the Audi A6. The main components are made of lightweight aluminium, which reduces the unsprung masses significantly. As on Audi’s sporty luxury saloon, the A8, adaptive air suspension makes up part of the standard package on the A6 allroad quattro.
Not only has wheelbase been increased significantly compared with the previous model, the car’s track has also widened: by 22 mm at the front to 1,596 mm and by 2 at the rear to 1,587 mm. Weight distribution between the front and rear axles has also been optimised by the development team to ensure that the A6 allroad quattro delivers a dynamic drive of the very highest calibre.
Relocated and lightened: the front suspension
In relation to the passenger cell, the four-link front suspension of the A6 allroad quattro has been moved forward by 83 millimetres compared with the previous model, thus ensuring a far better axle load distribution. Not only that, but the change in proportions looks good too as it makes the front overhang far shorter and thus gives the entire car a much more compact appearance.
Four aluminium transverse links guide each wheel. The axle subframe has a sheet-metal construction, the upper bearing block is made of cast aluminium. In keeping with the lightweight design principle, the anti-roll bar has a hollow design. The entire kinematics and elastokinematics of the suspension have been honed with the express purpose of maximising the vehicle’s dynamic handling capabilities and ride comfort. Lateral rigidity in particular has benefited from precision redevelopment of all link bearings. Enlarged rubber mountings on the subframe insulate the cabin from road impacts.
Sporty and comfortable: the steering
The new Audi A6 allroad quattro comes as standard with a hydraulic rack-and-pinion steering system featuring speed-sensitive power assistance - Audi servotronic. There is no end to the talents of the latest, most advanced version of the system. A minimum of effort is required when parking, at higher speeds the steering offers drivers utmost precision and excellent feedback from the road. And, with its high level of sensitivity around the straight-ahead position, the servotronic steering’s initial response characteristics are highly reassuring too.
The steering column in the new Audi A6 allroad quattro is adjustable by 50 millimetres in an axial direction and 40 millimetres vertically. Meticulous care has been taken to ensure that vibrations at the steering wheel are suppressed almost entirely.
Safe and dynamic: the rear suspension
One of Audi’s technical triumphs is now making its debut in the new A6 allroad quattro - the self-tracking trapezoidal-link rear suspension. Its highly complex, supremely effective construction achieves top-class ride comfort paired with infallible dynamic potential.
The trapezoidal links have a hollow, sand-cast structure made from aluminium. These torsionally rigid, non-flexing links absorb a large portion of the forces acting on the wheels. Together with the track rods located behind them, they thus determine the elastokinematic behaviour of the axle. The track rods have a lightweight sheet steel structure. All wheel location elements pivot at the flexibly mounted subframe by means of rubber-metal mountings. Four large, hydraulically damping mounts help to insulate the body against vibrations.
In terms of kinematics, the trapezoidal-link rear suspension has been purpose-developed for sporting characteristics. The reduction in the change in track width as a function of spring travel improves the straight-line stability, steering precision and handling of the A6 allroad quattro.
The entire construction has been configured to provide neutral handling characteristics with a slight tendency to understeer when the vehicle is pushed to its exceptionally high limits.
Riding on a carpet of air: adaptive air suspension
Adaptive air suspension comes as standard on the new Audi A6 allroad quattro. It creates a perfect synthesis of sporty handling on the one hand and silky ride comfort on the other, adding a further key dimension to the vehicle’s roadholding abilities in the process.
The new A6 allroad quattro has air spring struts at the front wheels, with the air bellows arranged concentrically around the infinitely adjustable twin-tube shock absorbers. The air-suspension bellows consist of a special, multi-layered elastomer material with polyamide cord threads to increase strength. The combination of the individual layers helps the new A6 allroad quattro to achieve outstanding ride qualities and respond sensitively to minor jolts.
Occupant comfort is enhanced by one of the inherent features of the air suspension system: the vibration characteristics remain constant at all times, regardless of the load the vehicle is carrying. This is because extra air is pumped into the springs by the compressor when the vehicle is heavily laden and discharged again when the load is removed. On the rear axle, the air springs and regulated shock absorbers are separated from one another. The advantage of this configuration, as with a conventional suspension, is that it allows a large through-loading width in the luggage compartment.
The adaptive air suspension together with all of its components - air bellows and shock absorbers included - is controlled electronically; to a large extent, its control characteristics adjust automatically depending on the type of road surface and driving style. Drivers of the A6 allroad quattro also have the option of altering the body’s ride height manually by up to 60 millimetres using the MMI terminal. There is a choice of five driving modes in all known as dynamic, automatic, comfort, allroad and lift.
In dynamic mode, which is the equivalent of a sports suspension, the body drops to leave 125 mm of ground clearance. This makes for even more agile handling, in addition to reducing drag and consequently fuel consumption. In automatic mode, the body is positioned 15 mm higher, but drops down to the dynamic level when the vehicle is driven for prolonged periods at over 120 km/h. If the comfort mode has been selected, the body is not lowered in this way.
The allroad mode provides a ground clearance of 175 mm; the body is lowered by 15 mm when the speed reaches 80 km/h and by a further 20 mm at 120 km/h. In the manually selected lift mode, the body hovers 185 mm above the ground to negotiate rough terrain at slow speeds - a whole 65 mm more than on the A6 Avant.
Should a speed of 35 km/h be exceeded, the control unit automatically switches to the allroad mode. Consequently, the A6 allroad quattro is perfectly at home on all roads and tracks.
Keeping a firm grip on things: the braking system
The new Audi A6 allroad quattro comes with a powerful braking system to harness the potential of its engines. Even the entry-level engines are paired with 16-inch brakes, and the mighty 4.2 FSI features a 17-inch system. The front brake discs measure 321 millimetres in diameter and 347 mm on the 4.2 FSI. The rear brake discs have a diameter of 302 mm (4.2 FSI: 330 mm with internally ventilated discs).
The system is operated via a dual-rate booster. At light to moderate rates of deceleration, it boosts the pedal force by a factor of 5.5, allowing for sensitive control of brake power. Above a predefined threshold, the boost factor is raised to 12, meaning a disproportionate increase in the rate of deceleration in relation to the force applied at the brake pedal - a clear asset for drivers preferring a particularly sporty style of driving. In the event of an emergency stop, the hazard warning lights come on automatically.
Safety built in: new ESP generation
All new Audi A6 allroad quattro models come with the latest-generation electronic stabilisation program, ESP 8, developed by Bosch. This system comprises the ABS anti-lock brake system with electronic brake-force distribution EBD and hydraulic brake assist. The traction control system ASR and the electronic differential lock EDL together with the yawing-moment control form the foundation for enhanced ESP safety. The brake disc wiping function is another new feature: when driving in the wet, the brake pads are briefly applied with light pressure to the discs at regular intervals. This keeps the braking system dry, preserving its ability to respond instantaneously at any time.
A new pressure control units allows the advanced version of the ESP system to intervene with even greater precision, particularly when the vehicle is understeering. In the vehicle’s “off-road” mode, which is activated by nudging the ESP button in the cockpit, the vehicle has greater traction and brake slip as well as controlled tractive and braking properties. Stabilising intervention takes place later - forward propulsion takes priority. This represents a major contribution to the highly flexible concept of the A6 allroad quattro. Off the beaten track, the A6 allroad quattro boasts an excellent performance while retaining its dynamic on-road characteristics.
This technology predestines the A6 allroad quattro for use off the beaten track, as does the permanent four-wheel drive and the adaptive shock absorber control, which also covers the specific conditions encountered in rough terrain. It is here that the high ground clearance and the generous angles of approach (18.3 degrees) and departure (21.5 degrees) truly come into their own. The A6 allroad quattro has a maximum fording depth of 30 cm. It is well-protected against stone chipping thanks to the underride protectors front and rear and the add-on parts along the vehicle’s flanks.
The electromechanical parking brake
The electromechanical parking brake in the new A6 allroad quattro, which is operated via a pull/push control on the centre console, offers considerable practical benefits over and above all the usual functions of a conventional handbrake.
By way of an integral starting aid, the electromechanical parking brake makes it easier to pull away without jolts or rolling backwards on an incline. The system calculates the ideal moment for releasing the parking brake on the basis of data such as the transmission position selected, the accelerator pedal position, engine speed and the angle of inclination. On cars with a manual gearbox, the system also takes the position of the clutch pedal into account.
It goes without saying that the electromechanical parking brake also has the emergency braking function stipulated by law: above a speed of 8 km/h the driver can stop the A6 allroad quattro simply by pulling on the switch.
Within just over a second, the system builds up a deceleration force of 8 m/s² - far more than with a conventional handbrake as the electromechanical parking brake acts on all four wheels.
Elegant and robust: wheels and tyres
Even the six-cylinder versions of the new Audi A6 allroad quattro come as standard with elegant 8 J x 17 light-alloy wheels sporting a 7-arm rotor design and shod with 225/55 R 17 tyres. The 4.2 FSI rides on 18-inch wheels with a 10-spoke design and size 245/45 R 18 tyres; this same wheel is available as an option for the six-cylinder models. Two-piece cast 18-inch wheels in a 5-arm “Aero” design can be specified as an option in conjunction with any engine.
All of the tyres are 22 millimetres wider in diameter than on the A6 Avant. As an option, 245/45 R 18 all-terrain tyres are available whose special tread pattern ensures better progress off-road. They are approved for a top speed of 210 km/h. In addition to the all-terrain tread, these tyres are especially resistant to any cuts in the tread or the sidewalls. A reinforced underguard for the engine and transmission is also fitted together with the all-terrain tyres. All models come as standard with the Audi tyre mobility system, but may also be supplied with a space-saving spare wheel as an option. A permanent tyre pressure monitoring system can also be found on the list of optional extras.
Standard equipment
The standard-specification equipment level closely reflects the premium nature of the new A6 allroad quattro. Aluminium door sill trims and inlays inside the car (in Vavona wood on the 4.2 FSI) speak volumes of the brand’s great attention to detail. The seats are upholstered in Taurus cloth, the rear seat has an asymmetrically split folding backrest. The range-topping 4.2 FSI model comes with electrically adjustable seats including a centre armrest, all upholstered in Milano leather.
Deluxe automatic air conditioning with separate temperature controls for driver and front passenger ensures high levels of comfort and convenience. The 4.2 FSI leaves the factory equipped with deluxe automatic air conditioning plus including a whole host of extra functions. The Multi Media Interface “MMI basic”, comprising not only the 6.5-inch monochrome display, but also an integrated radio with CD player and speakers, boasts an operating logic whose intuitive design is still unsurpassed by the competition. Front fog lights, a light and rain sensor as well as a headlight washer system make up part of the standard specification too, with the 4.2 FSI adding the driver information system and an anti-theft alarm system for good measure.
The electromechanical parking brake serves both as a starting aid with automatic release of the brakes and as an emergency braking function. The latest-generation electronic stabilisation program incorporates a brake assist function plus a special “off-road” mode. The six-cylinder models ride on 17-inch light-alloy wheels with size 225/55 R 17 tyres and the 4.2 FSI comes complete with 18-inch wheels shod with size 245/45 R 18 tyres.
quattro permanent four-wheel drive, the adaptive air suspension system with its high maximum ground clearance, along with the speed-sensitive servotronic power steering, mean that the A6 allroad quattro can continue to display its expert capabilities far away from tarmac roads. Once there, the bodywork is protected by the add-on parts along the vehicle’s flanks and the stainless steel underride protectors at the front and rear.
Sporty and active customers will quickly come to appreciate the double load floor with dirt-resistant tray. The securing rails and adjustable fastening rings together with the aluminium roof rails round off the versatile character of the Audi A6 allroad quattro.
In Germany, the 3.2 FSI costs €50,600, while the 2.7 TDI is priced at €47,600 and the 3.0 TDI at €50,600, with both diesel models including a diesel particulate filter. When the new A6 allroad quattro first goes on sale, the two diesel models and the 3.2 FSI model will be available immediately, all with 6-speed tiptronic. These will be followed shortly afterwards by the 6-speed manual versions of the V6 petrol and 3.0 TDI models, together with the 4.2 FSI.
Optional extras
The selection of optional extras for the A6 allroad quattro also leaves nothing to be desired. A personal touch can be added to the exterior design by opting for the full paint finish, which adds body-coloured bumpers, flared wheel arches and door sill panelling in a matt finish. Further visual highlights include the aluminium trim for the window surrounds and the door strips as well as the aluminium-look roof rails. The optional full paint finish also includes the aluminium styling package, which can in addition be ordered as an optional extra.
A range of interior colours, leather and cloth upholsteries and inlays offer ample scope for transforming every A6 allroad quattro into an unmistakable, one-of-a-kind specimen. A lighting package can be added for discreet illumination of the centre console, the footwells and the door exit area.
The standard MMI basic system can be upgraded to either MMI basic plus or MMI. The system can also be expanded by the addition of extra individual components, including a TV tuner, a speech control system, a DVD navigation system and the camera-aided Audi parking system advanced.
For the ultimate in listening pleasure there is the BOSE surround sound system. The hands-free car phone is linked up to the MMI system by Bluetooth technology.
The optional sports seats for the front, which are also available in an electrically adjustable version, offer excellent support and comfort while the deluxe automatic air conditioning plus system (standard on 4.2 FSI) enhances the well-being of all passengers.
Enhanced visibility is available in the form of the adaptive light system including xenon plus technology. The dynamic cornering light is able to illuminate the way ahead on twisty stretches of road thanks to its pivoting headlights. The xenon plus package also includes daytime running lights and LED brake lights.
The “advanced key” system acts as an electronic access and authorisation system. An electronic pulse generator is incorporated into the key which communicates with the vehicle. The engine can either be started by pressing the starter switch on the centre console or in the conventional way by turning the key in the ignition.
Luggage and sports equipment also travels first class in the new Audi A6 allroad quattro. Numerous ingenious solutions are available to give the roomy luggage compartment even greater versatility- a telescopic bar, for instance, or a retaining strap, cycle rack or storage box. A load-through hatch including ski bag accommodates longer items and the electrically operated tailgate opens and closes at the touch of a button.
18-inch wheels and tyres are optionally available for the six-cylinder models and special 18-inch all-terrain tyres for all engine versions. Any customer wishes that are not already covered by the broad choice of optional extras can be addressed to quattro GmbH, whose “exclusive” programme offers virtually limitless scope for customisation.
