Audi all-terrain Avant bringing major efficiency gains and even more extensive specification to the UK is now available to order.

• New generation version of all-terrain A6 now available priced from £43,150 OTR to £49,445 OTR -  first deliveries in July
• Four engine options – 3.0 TFSI with 310PS and 440Nm, 3.0 TDI with 204PS and 450Nm, 3.0 TDI with 245PS and 580Nm, 3.0 BiTDI with 313PS and 650Nm
• Fuel consumption reduced by as much as 20 per cent
• Four-level adaptive air suspension as standard

The Audi A6 Avant reveals its even tougher and more intrepid alter ego this week as the new, third generation A6 allroad quattro opens for UK order combining rugged looks with the all-weather reassurance of quattro all-wheel-drive and four-level height adjustable air suspension. The new A6 allroad quattro with four powerful V6 engine options is priced from £43,150 OTR to £49,445 OTR and will reach its first customers here in July.

Like the saloon and ‘standard’ Avant, the A6 allroad quattro has been constructed using the latest Audi ultra lightweight construction principles, and with aluminium components making up roughly 20 per cent of its body total vehicle weight has been reduced by as much as 70 kilograms compared with the previous model.

This creates the best possible operating conditions for the four powerful and cultivated V6 engines that make up the range, all of which combine forced induction with direct injection, and all of which are backed up by a start-stop system and innovative thermal management, helping to improve fuel economy by as much as 20 per cent compared with the previous model.

The petrol-powered option is the 3.0-litre TFSI, which is boosted by a mechanically driven supercharger and produces 310PS and 440Nm of torque. It powers the A6 allroad quattro from rest to 62mph in 5.9 seconds on the way to an electronically limited top speed of 155mph, and yet can still achieve 31.7mpg according to the combined cycle test.

Choice of three TDIs

The TDI range comprises three 3.0-litre V6 units, the first two of which deliver 204PS with peak torque of 450Nm and 245PS with 580Nm with the help of a single turbocharger. The 204PS version is the efficiency champion, achieving a combined economy figure of 46.3mpg with CO2 output of 159g CO2/km, despite strong 7.5-second zero to 62mph acceleration. Its 245PS counterpart runs it impressively close, with 44.8mpg potential and 165g/km CO2 output combined, along with 6.6-second acceleration.

The top-ranking diesel, the new BiTDI, uses two turbochargers to inject 313PS and 650Nm, enough to power the A6 allroad to 62mph in just 5.6 seconds on the way to a governed 155mph top speed. It complements this sports car-style performance with a surprisingly sports car-style engine note that comes courtesy of an innovative sound actuator in an auxiliary channel of the exhaust system, but its economy figures remain resolutely diesel-like, with up to 42.2mpg possible equating to 176g/km CO2 output.

The three single turbocharger engines are paired with the seven-speed S tronic dual-clutch transmission with its wide ratio spreads and rapid fire shifts. The BiTDI uses the latest eight-speed tiptronic automatic transmission.

The plentiful power these refined and sophisticated units supply is expertly handled by the latest generation quattro all-wheel-drive system with 40:60 front-to-rear torque split, and the body rises or lowers on its four-level air springs according to prevailing driving conditions and speeds, ensuring that the A6 allroad quattro feels equally at home in the tightest of corners or on the roughest of tracks.

New electromechanical power steering combines accurate feedback with minimal energy consumption as it draws no power when in the straight-ahead position, and an optional dynamic steering system is also available to adjust the steering ratio to the speed driven. This can be combined with an optional sport differential that can rapidly vary torque distribution between the rear wheels for optimum adjustability.

The rough-and-tumble capability of the A6 allroad quattro is reflected in exterior features such as extended side sills, flared wings and protective front and rear stainless steel underbody guards. The wheel arches, bumpers and sills are painted in a contrasting colour, but can be body-coloured as an option.

The interior of the Audi A6 allroad quattro offers plenty of space thanks to the long wheelbase of 2,905 millimetres. It combines a clean, elegant design, outstanding ergonomics and exemplary workmanship with a suitably ample quota of equipment. This includes 18-inch alloy wheels, Milano leather upholstery, satellite navigation, the Multi Media Interface (MMI) linked to a 6.5-inch retractable colour display, the Audi parking system plus, cruise control, Bluetooth mobile phone preparation, light and rain sensors and the Audi drive select adaptive dynamics system.

Audi drive select enables the driver to adjust the operating characteristics of the steering, the air suspension, the throttle, the automatic transmission, the automatic air conditioning and the lighting. It offers five modes – Comfort, Dynamic, Automatic, Individual and Efficiency, the latter configuring the most economy-focused settings for all the functions controlled. Where the optional sport differential, dynamic steering and adaptive cruise control systems are fitted these can also be fine-tuned via the drive select system.

Outstanding versatility

The luggage compartment has a capacity of 565 litres, and the standard split rear seat can be folded down to increase this to 1,680 litres. Numerous standard and optional features underscore its practicality, including a rail system into which a load-securing kit for dividing the luggage compartment can be inserted, tensioning straps on the left wall and a double loading floor.

A wide choice of options is also available, including a head-up display which can project important information onto the windscreen, the hard drive-based MMI Navigation plus system with touchpad operation (MMI touch) and retractable eight-inch monitor, a 15-speaker Bang & Olufsen audio system, comfort seats with a ventilation and massage function and a panoramic glass roof.

In-car internet access

Technophiles can indulge themselves even more completely by specifying the Mobile Phone Preparation – High option with Audi connect. This brings online services to the car via UMTS (3G), including Google Earth mapping, Google Street View, the all-new Audi traffic information online function, which uses mobile phone signals to pinpoint traffic congestion or accident blackspots in real time, and Audi music stream web radio. It also creates a Wi-Fi hotspot within the car, enabling passengers to surf the internet and email.

The list of safety-focused systems is no less impressive, and includes radar-based adaptive cruise control, the Audi active lane assist lane departure warning system, the Audi side assist blind spot detection system and night vision using thermal imaging.

Compact SUV study unveiled at Auto China adopts the coveted RS badge and the usual extreme performance credentials

• Conceptual interpretation of a high-performance Q3 delivers 360PS from its five-cylinder, 2.5-litre TFSI petrol engine
• 0-62mpg in 5.2 seconds, 165mph top speed

Two worlds are about to collide in China, where for the first time in its history Audi will attach the overtly sporting RS badge to an SUV. The RS Q3 concept will be one of the stars of the 2012 Beijing Show (Auto China, April 27 to May 2), and as its more muscular body conceals a turbo charged five-cylinder engine delivering 360PS there is no doubt that its bite will justify its bark.

Finished in a combination of striking Ordos Blue matt and blue ‘clearcoat’ paint, the Audi RS Q3 concept sits around 25mm lower than normal on 20-inch alloy wheels with high gloss outer surfaces and sandblasted innards. These are wrapped in 255/30 section tyres, their unusually low profile serving as another reminder that this is as much an RS model as it is an SUV.

The styling treatment underlines this with classic RS hallmarks such as the honeycomb-style grille, deeper air intakes and side sills, a pronounced rear diffuser and large oval exhaust tailpipes. Lightweight carbon fibre-reinforced polymer (CFRP) is used for elements such as the front spoiler, sections of the air intakes, the door mirror housings and the headlight inserts.

In the interior of the Audi RS Q3 concept, which gets plenty of light through a glass sunroof, black is the dominant colour, and is set off by dark blue contrasting Alcantara sections within the Fine Nappa leather-upholstered seats. This contrasting blue colour is also employed in the door trims and in decorative inlays produced by weaving brilliant blue luminescent glass fibres into CFRP. The steering wheel, finished in black Velvet leather, has large control stalks also made of CFRP, which are framed by aluminium accents.

The lightweight door handles will be familiar from other RS models, and RS badges adorn the instrument cluster, the seatbacks, door sill plates and floor mats. In the rev counter, Chinese characters replace the usual Arabic numerals.

The engine compartment also continues the theme. A layered-carbon trim panel covers the area around the five-cylinder engine, which sports a red valve cover, and two laterally arranged ventilation screens feed air to the engine. In a nod to motor racing, the cylinder numbers are marked on their spark plug covers. An aluminium housing holds the open sports air filter, and the filtered air tube is made of stainless steel.

Formidable five-cylinder

The powerful 2.5-litre TFSI engine combines direct petrol injection and turbocharging in the best Audi traditions. From 2,480 cc of displacement, it generates 360PS, enough to catapult the concept car from rest to 62mph in 5.2 seconds, and to take it on to a top speed of 165mph.

A seven-speed S tronic twin-clutch transmission transfers the forces of the sweet-sounding five-cylinder unit to the quattro permanent all-wheel drive system. Generally, it directs these forces almost exclusively to the front wheels. When a loss of grip is detected there, it can redistribute forces to the rear axle via a hydraulic multi-plate clutch with electronic control – instantaneously and variably.

Lightweight construction pioneer highlights its technological lead

• Dynamic and efficient: Audi – pioneer of lightweight design for enhanced performance and optimised efficiency
• Aluminium-bodied A5 prototype aids development of the ASF concept
• Over 550,000 Audi models with an aluminium body since 1994
• New materials and technologies for the cars of tomorrow

A lightweight Audi A5 Coupe prototype has jettisoned over 100kg by swapping steel for advanced aluminium and carbon fibre construction in the interest of fuel economy, emissions reduction and handling agility. The A5 project is the latest example of the pioneering work undertaken by the Vorsprung durch Technik brand to extend efficiency optimisation measures well beyond the engine bay.

Taking an existing steel-bodied production car as its basis, the A5 project car clearly demonstrates the benefits of the aluminium Audi Space Frame (ASF) concept with which Audi broke new ground 15 years ago, and which test beds of this kind help to evolve and improve. Use of the ASF principle reduces the weight of a car body by at least 40 per cent compared with conventional steel construction, and this shows in a kerb weight of 1,310kg for the aluminium A5 prototype, versus a total of 1,420kg for the equivalent steel-bodied series production model.

Thanks to the significant weight loss, achieved by mounting aluminium and carbon fibre-reinforced plastics onto the aluminium Audi Space Frame (ASF), the A5 prototype is able to use a four-cylinder engine with its attendant economy and emissions advantages to deliver the performance of a higher output V6.

With the acclaimed 2.0-litre, 211PS Turbo FSI engine, the A5 achieves a power-to-weight ratio of 161PS per tonne. For comparison, the ‘standard’ A5 3.2 FSI V6 quattro with 265PS, which tips the scales at 1,540kg, shades it only by a fraction at 172PS per tonne.

The lightweight design of the test car not only enables a smaller engine to supplement a larger one with no impact on performance and gains in economy and emissions, but also has a knock-on effect on ancillaries such as the brakes and transmission, which can also be reduced in size and weight. It also enables the car to change direction noticeably more keenly and nimbly and, thanks to the reduction in unsprung weight, to ride with even more refinement.

15 years of lightweight construction experience

Over the past 15 years, Audi has employed the ASF principle in two generations of A8 luxury saloon, in the hyper-efficient, ahead-of-its-time A2 compact hatchback and in the celebrated R8 super car. ASF has also been re-interpreted in the creation of the latest TT Coupe and Roadster, which feature advanced steel and aluminium ‘hybrid’ construction that allows for outstanding weight distribution.

“One of our most enduring aims for the future is to reverse the weight spiral,” says Michael Dick, Member of the Board of Management of AUDI AG responsible for Technical Development. “Lightweight design is the foundation of our entire approach to improving efficiency.”

Lightweight design is a strategic responsibility at Audi. It makes a significant contribution to dynamic potential and efficiency, helping to conserve resources and reduce operating costs. The electric drives of the future will add additional weight to the car and will initially only offer a limited range, making systematic lightweight design all the more important.

ASF: the reversal of the weight spiral

The reversal of the weight spiral that Audi initiated with the ASF principle which began with the Audi A8 of 1993 has major efficiency advantages. Every 100kg saved reduces fuel consumption by 0.3 to 0.5 litres per 100 kilometres, corresponding to a reduction of 8 to 11 grams of CO2 per kilometre. A lighter body is also the starting point for weight reductions on other parts of the car, such as the chassis or the fuel tank.

Meanwhile lightweight bodies are an absolute prerequisite for the electric drive systems of the future with their heavy batteries. The performance and range expected by customers cannot be achieved without them.

Audi has already built more than 550,000 vehicles with an aluminium body. Added to this are roughly 9,000 Lamborghinis – no other manufacturer in the world can even come close in terms of the number of vehicles or their diversity.

The ASF technology is an unparalleled success story. Audi has increased its lead step by step: in alloys, in the reduction of the number of parts and in production efficiency. Numerous innovations in development and production have raised the level of automation from 25 to over 80 percent, which is nearly on par with steel body construction.

In fabrication, traditional spot welding is being replaced by joining methods developed by Audi, including punch riveting, bonding or laser-MIG hybrid welding. In the TT and the R8, self-tapping screws are used to join many of the components. Another innovation is the laser-welded invisible seam on the roof of the TT.

A8, R8, TT and TT Roadster: the state of the art

The second generation of the A8 and the R8, TT Coupé and TT Roadster sports cars document the current state of the ASF technology. The superstructure of the current A8 weighs 218kg while the aluminium body of the R8, whose co-supporting engine frame is made of ultra light magnesium, tips the scales at 210 kg.

The TT Coupé and Roadster bodies weigh 206 kg and 251 kg respectively while the TT “family” also features an additional innovation. To ideally balance the axle loads between the front and back, Audi developed an innovative hybrid construction for its compact sports cars: Most of the body is made of aluminium, but steel is used in the rear.

Depending on the model, the kerb weight of the TT has been reduced by between 20 and 90 kg compared to the previous model which had an all-steel body. At the same time, the static torsional rigidity of the Coupé increased by 50 percent and that of the Roadster by an even more impressive 100 per cent.

The ASF provides the foundation for precise handling and a high level of passive safety. A lighter car has to dissipate less kinetic energy and is also does less damage to others involved in an accident. The lightweight design combines chassis responsiveness and efficiency in typical Audi fashion.

Foundations were laid almost 100 years ago

NSU built the Type 8/24, featuring a body made entirely of aluminium, in 1913, and 10 years later, the Audi Type K wore an experimental streamlined skin of this same material. In the 1930s, specialists from the Racing department of Auto Union manufactured aluminium panels by hand and used them to build the bodies and streamlining panels for their spectacular racing cars and land speed record cars.

Lightweight design advanced to the level of a strategic project at Audi in 1982 to invent a self-supporting body with a material roughly two-thirds lighter than conventional steel and also with a new geometry tailored to this material – the Audi Space Frame.

In 1985, Audi presented the body of an Audi 100 made of aluminium but still using a conventional monocoque design. The legendary concept sports cars of 1991, the Audi Avus quattro and the Audi quattro Spyder, had skins of the light metal but underneath were still supporting frames.

The new technology was ready for series production in 1993. A shining silver showcar with an unpainted body of polished aluminium was on display at the Frankfurt Motor Show. The predecessor to the A8 bore the designation ASF, the abbreviation for Audi Space Frame. The production model that debuted the following year was a milestone – the first large-volume production car with a self-supporting aluminium body.

The A8 paved the way for Audi into the premium league and it also sparked new developments for the traditional material of steel. The principle embodied by the first A8 still applies today: Die castings and extruded sections form a framework-like skeleton that incorporates aluminium panels as co-supporting elements. The components with their various cross-sections and shapes combine optimal function with low weight.

The Aluminium and Lightweight Design Centre

Audi established a special Aluminium Centre in Neckarsulm for development, production planning and quality assurance in 1994. The Aluminium and Lightweight Design Centre experiments with high-strength steels, tailored blanks, fibre-reinforced plastics and magnesium.

Heinrich Timm, the Head of the Aluminium and Lightweight Design Centre, says: “Aluminium remains the primary material, but we are intensively investigating the other materials, with our primary focus on fibre-reinforced composites.”

The lessons learned at the Aluminium and Lightweight Design Centre innovation foundry, which employs 150, have already served as the basis for a three-digit number of patents in development and production – a balance they can be proud of. The European Patent Office named Audi “European Inventor of the Year 2008” for its achievements with the ASF technology.

Lightweight design in the rest of the vehicle

Audi also makes systematic use of lightweight design in the drive chain and the chassis. Many engines uses aluminium and vermicular graphite cast iron, which is the result of a high-tech production process, to reduce the weight of the crankcase. Many models have chassis with predominately aluminium parts.

Carbon fibre-ceramic brake discs are available as an option in the high-performance models. Other highlights of lightweight design include brake callipers, bonnets and boot lids, side panels or cover components made of aluminium and steering wheel rims or instrument panel mounts made of magnesium.

Experience from the world of motor sports flows back into the development work – the reduction and distribution of weight are extremely important for Audi’s pioneering diesel-engined Le Mans sports-prototypes and its DTM (touring) cars. The race cars provide the production development engineers with important information about carbon and its combination with metal.

Research continues into new materials and alloys, with the focus on minimal weight with maximum durability as well as design and fabrication compatible with the materials.
