The active sport differential distributes torque from the engine in continuously variable proportions between the rear wheels.

Targeted control of the power flow enables the car to steer even more spontaneously and directly into bends, and produces a far more robust directional stability.

Depending on the steering angle, lateral acceleration, yaw angle, road speed and other signals, the control unit calculates the most suitable distribution of torque to the wheels for every driving situation.

When the steering wheel is turned or the car is accelerated in a bend, power is redirected in a controlled manner to the outer rear wheel. This has the effect of “forcing” the car into the corner so that it accurately follows the angle of the front wheels.

The difference in tractive force between the left and right wheels exerts an additional steering effect, so that the usual corrections by the driver at the steering wheel are no longer needed. Understeer is completely eliminated. Active torque distribution is based on an entirely new design principle for the rear-axle differential.

So that the new high-tech unit can also divert torque to the outer wheel of the axle, which revolves faster than the inner wheel when cornering, the classic rear-axle differential has been equipped with superposition stages on the left and right, each with a multi-plate clutch running in an oil bath. The clutches are activated by an electro-hydraulic actuator. The superposition stage rotates ten percent faster than the half-shaft that normally drives the wheel; the two components can be coupled by the multi-plate clutch. If the clutch is engaged, the wheel is accelerated by the superposition stage, which is running at a higher speed, and thus receives an additional torque input.

The differential reduces the tractive force reaching the opposite wheel accordingly. In most driving situations, almost the complete input torque can be diverted to one rear wheel in this way. The maximum difference in torque between the wheels is 1,800 newton metres.

As a car manufacturer, we can never claim to have a truly positive impact on the environment – and nor should anyone else in the automotive industry. But what we can be certain about is that the billions of pounds we’re investing in responsible technologies over the next decade will place Audi at the forefront of efficient motoring and manufacture.

The principles of constant innovation at the heart of Vorsprung durch Technik already place Audi in a strong position. Technologies such as our lightweight space frames, efficient TDI engines and our waste-reducing manufacturing processes all serve to cut CO2 emissions. And we’ve been doing this for years – we’ve improved our cars’ efficiency by over a third during the last 20 years, and by 2012 we pledge to reduce the emissions of our vehicles by a further 20 per cent.

We’re continuing to work hard today to create a clean driving tomorrow and have a number of very exciting developments to offer our customers over the coming years. Read on to learn more about our commitment to reducing our, and your, impact on the environment.

In the UK

Whilst our colleagues in Germany are doing everything they can to make our cars more efficient, at Audi Head Office in Milton Keynes we are also committed to reducing waste.  A lot of what we do isn’t very innovative, you probably recycle paper and switch off unused appliances at home, but it does make a significant difference to our carbon footprint.  On top of this, by investing in technologies like intelligent lighting and video conferencing we are able to work efficiently without compromising our business standards.  And by joining forces with Audi UK’s franchise operation to minimise waste, we are generating tangible environmental benefits across the whole of the network.

  • Audi shows the benchmark of future design language in Los Angeles
  • Head of Development Prof. Dr. Ulrich Hackenberg: “Perfect showcase of Audi DNA”
  • Head of Design Marc Lichte: “A foretaste of the future of Audi”

 

 

Ingolstadt/Los Angeles, November 19, 2014- Audi is launching into a new design era: At the Los Angeles Auto Show, Marc Lichte, Head of Design, is presenting the Audi prologue concept car. Lichte is giving the Audi brand a new styling direction in the large coupe.

“When he moved to Audi, Marc Lichte launched a design offensive,” says Prof. Dr. Ulrich Hackenberg, Board Member for Development, who brought him to Ingolstadt in 2014. “His clear philosophy and precise understanding of Audi DNA let him develop a design strategy that is opening up entirely new perspectives for us. It is progressive and highly emotional; it expresses the technological competence and quality claim of the brand perfectly. The Audi prologue is its first proponent – it is a ‘signature car’ for Audi.”

Marc Lichte himself describes the character of the show car in this way: “Audi stands for sportiness, lightweight design and the quattro permanent all-wheel drive. In the Audi prologue, we are expressing this know-how in a new form – we have put the sportiest car in the luxury segment on wheels. Our team took new approaches in both exterior and interior design.”

Audi design is now expressing progressive technology even more powerfully. The two-door coupe has a flowing, elegant shape and taut design. Its forms and lines are unmistakable and introduce many new ideas. In the clear and unobstructed interior, the architecture melds with the display and operating concept to create a new type of unit. The entire front of the instrument panel is a large touch display, and a portion of the user interface operates with a new type of OLED display made of organic LEDs.

The show car’s technology combines power, comfort and efficiency. The 4.0 TFSI produces up to 605PS of power and 750 Nm (553.2 lb-ft) of torque; it accelerates the Audi prologue from 0 to 62mph in 3.7 seconds. Its dynamic all-wheel steering, in which the rear wheels can turn up to five degrees, makes the large couple extremely responsive and stable while driving.

Harmonious proportions: exterior

The Audi prologue is somewhat shorter and flatter than today’s production A8, with a length of 5.10 metres, wheelbase of 2.94 metres, width of 1.95 metres and height of 1.39 metres. A dominant feature at its low front end is a Singleframe grille displaying the four rings that is integrated into the automobile architecture. The large radiator grille has been widened much more, and it is positioned lower than on today’s production models. Its strong horizontal effect expresses an image of powerful dynamics. The cross bars have a finely structured diamond pattern, and their ends are split.

The headlights – shaped like wide, flat wedges – are located with their tips above the Singleframe. They present high-resolution Matrix laser technology: an innovation from Audi which opens up new approaches to headlight design and enables completely new functionalities. The pupils of the headlights are formed by a projection lens with a laser light source – they generate a matrix that illuminates the entire street in high resolution. Hovering beneath this element are five plastic lenses that are supplied with light via a glass fibre bundle, which are mounted to a lightweight structure and further extend the high-beam light. The new laser technology lets lighting designers create an extremely lightweight, compact and elegant eye-shaped form.

Audi quattro DNA visualised

Also new is the sculptural form of the air intakes under the headlights – the distinctive air intakes have diamond pattern screens in their interiors. A dynamically contoured blade, which is clearly separated from the bumper by a gap, elicits associations to motor sport. Mounted to it are two additional spoilers in glossy black, which give the show car an even stronger and wider stance on the road.

In side profile, its flowing silhouette expresses the character of forward motion in the Audi prologue. Balanced proportions put equal emphasis on the front and rear wheels – a clear reference to the quattro DNA of Audi. The powerful 22-inch wheels are set in widely flared wheel arches. They are fitted with tyres of size 285/30. Each wheel’s ten intertwining Y spokes project a filigreed, three-dimensional and powerful image.

Edges above the wheel arches refer back to the Ur-quattro

A characteristic feature of the Audi prologue are the flared shoulders above the wheels, front and rear. Like the blisters of the original Audi Ur‑quattro of the 1980s, they visualise the quattro drive – but they are no longer just added on, rather they are worked into the flow of the base architecture. In a side view, the shoulders form two gentle arcs above the wheels, which break up the somewhat lower shoulder line between the wheels.

The wings, doors and rear side panels show curved muscular surfaces. The lower door area has a low concave shape that runs upwards to the rear – a motif that links to the design theme of air inlets. The side sills are drawn inward; glossy black aprons form a continuation of the front spoiler. All lines and surfaces on the Audi prologue show car are logically interrelated, which is typical Audi.

Aluminium components in hand-finished quality

The door mirrors are small aluminium sculptures: The mirror housings in the form of a shell create a flowing transition to the window slot trim. They also integrate the open-door sensor surfaces. The doors have no handles, and they are opened electromechanically when the illuminated sensor surfaces are touched.

Vast areas of the stiff multimaterial body of the Audi prologue consist of aluminium and ultra-high-strength steel. The windows are framed by matt and polished aluminium trim strips. At the end of the low roof dome, the window framing transitions into a solid surface of aluminium; its workmanship illustrates the handcraft-like manufacturing quality of Audi, and it enables lowering of the windows despite the C-pillars. This area integrates the fuel tank lid on the right side of the show car. It has an electric opening mechanism and can be lowered completely into the C-pillar by pressing a button in the interior. For enhanced convenience in refuelling, the tank closure does not have a cap. The paint is a light diva grey, a new type of pearl effect paint, which has a warm and elegant appearance.

Rear section drives the whole car forward

The rear section of the Audi prologue also breaks with conventions. It is angled in the driving direction and is reminiscent of the side and rear views of a luxurious yacht; the sickle-shaped seam between the side panel and the bumper emphasises this dynamism. The edge of the boot lid, which is executed as a discreet spoiler, picks up on the blister line coming from the side panel. Between the C-pillars, the rear window has a concave inward curve – it closes off the passenger compartment while enabling convenient cargo loading with the separate boot lid. The Audi prologue unites the positive aspects of a saloon with the aesthetic highlights of a coupe.

The unconventional design of the LED rear lights with their 3D glass gives the tail lights all of the benefits of the new design: the new, long tail lights run across the entire width of the car. At its termination point, the light illuminates the frame of the embossed 3D form. Fine lines in the 3D glass appear to hover in the middle of the light. The brake light is located deep inside the lighting unit. When braking, the bottom of the 3D imprint is also illuminated, which makes the light appear to move towards the observer. This configuration on different levels, and the alternation between 2D and 3D lighting functions lets the observer experience the tail lights in an entirely new dynamic way.

Beneath the bumper, there is a diffuser made of black anodised aluminium; like the front blade, it extends over the full width of the car as a separate, significantly recessed element. The diffuser integrates two trapezoid-shaped inlets which visually coordinate with the embossed tail lights and house the exhaust system tailpipes.

Luxurious and innovative: interior and operating concept

The spacious interior of the Audi prologue is like a luxurious lounge. It is based on Gran Turismo design, and it enables both very focused driving and relaxed touring. The interface visually adapts to the specific driving style. The interior marks the beginning of a new design era at Audi, in which the architecture merges with the operating concept to form one unit. The surfaces for displays and controls are innovatively integrated into the instrument panel and console of the centre tunnel, and the infotainment system brings driver and passenger into dialog with one another.

When entering the vehicle, the four-seat coupe receives its passengers with polite hospitality. The “butler” – an innovative intelligent software program – identifies them based on their smartphones and adjusts the seats and climate control system according to their preferences. The system also makes recommendations for music and route planning that are oriented towards the owner’s preferences. The Easy Slot system, an advanced development of the Audi phone box, is located under lids in the centre console. A special mechanism networks the smartphones of passengers to the vehicle infotainment system and charges them.

Generous open interior space

Tautly stretched lines and lean geometric forms give the interior a light and clear ambience. The instrument panel has a light and elegant appearance with its strictly horizontal layout that is not interrupted anywhere, and it emphasises the generous interior width. It lowers itself towards the interior on two levels. The upper level is positioned, like a roof, above the Audi virtual cockpit future – an advanced development of the Audi virtual cockpit – and above the line of air vents. It is part of the wrap-around – a large arc that encircles the driver and front passenger.

A second wrap-around joins the front and rear sections of the interior and is already quite visible from the exterior. The centre console with its pass-through also appears to hover, as do the front seats, whose rails are mounted on the tunnel and side sills. The head restraints of the two rear bucket seats are lowered when not in use; they automatically extend when a passenger enters the rear seating area with the electric easy entry function.

When the sound system is activated, a new type of sound spoiler extends from the rear shelf; it optimally produces a premium sound in the car that is typical of Audi.

Entire front of instrument panel becomes a display

A radically new type of display and operating concept is embedded in the elegant architecture. Across its full width, the front of the instrument panel is designed to be a display surface which integrates three touch displays. The driver-oriented display to the left of the steering wheel is used to control functions for lighting and assistance systems. The driver-oriented operating unit to the right contains media controls. The front passenger faces a widescreen display that is integrated into the full surface of the instrument panel; it is used to individually and conveniently control entertainment features.

The new type of front passenger display enables digital interaction between the driver and front passenger for the first time. A wiping movement by the passenger is all it takes to send pre-configured routes to the driver’s display and input them into the Audi virtual cockpit future.

On the console of the centre tunnel, there is a fourth flexible touch display that is ergonomically adapted to the driver; it is used for climate control, handwriting input and other vehicle settings. This display consists primarily of an extremely thin, bendable OLED film (OLED: organic light emitting diodes), and it displays extremely sharp images that are rich in contrast. When not in use, the OLED display is integrated flush to the center console and is nearly invisible. When the car is started, the flexible display stands up. The fact that it bends ensures a constant distance to the hand which makes for better ergonomics. When operating the display, the wrist rests on the low-positioned gear selector lever of the eight-speed tiptronic. Designers have also redesigned the shift-by-wire lever. It is now integrated seamlessly into the centre console. Cupholders and smartphone slots are installed under lids on the centre console, to the left and right of the console support element.

Audi virtual cockpit future shows images on three levels

The Audi virtual cockpit future offers a glimpse into the future of the digital cockpit: High-resolution displays and three mirrors generate a virtual stage on three levels – a fascinating view with visual depth. In the navigation view, the first level presents information that is important for driving; levels two and three generate the depth effect in the cockpit. Structuring the information on different levels makes it better organized and easier for the driver to comprehend. The content and colours of the Audi virtual cockpit future change as a function of driving style – when required, the display switches over to Sport mode with special presentation of the relevant information such as engine rpm, temperatures and charge pressure.

Inside the Audi prologue, every detail clearly illustrates its exclusive character. 
A finely crafted perforated panel covers the air vents. If the driver sets the blower to a higher stage, the panel retracts downwards.

White LED light conductors trace the distinctive lines of the interior, starting at the doors. A large aluminium brace forms the steering wheel spokes; it harmonises with the bars on the displays and the door pull handles. All aluminium accents show perfection in craftsmanship: Their surfaces have matt finishes, and the edges are polished – a fine interplay of gloss levels.

Natural materials communicate a new luxury

For Audi designers from the Colour & Trim area, natural materials are the new luxury; all of the materials in the show car fascinate with their authenticity. The surfaces of the seats and seat backs, the dashboard, the console on the centre tunnel and the armrests are covered in light-coloured “passion” leather – a new soft grade of leather that emphasises the natural characteristics of the animal hide.

Soft nubuck leather, also in a light colour, covers the backs of the seats and the side panel trim of the rear seating area. On the instrument panel, the grey-brown trim of the lower section provides another strong accent. The wrap-around is upholstered in dark “passion” leather; here, and in many other areas, aluminium trim strips contrast with panels of open-grained silver-grey elm wood veneer.

Dynamic yet convenient: the technology

The technology of the Audi prologue is as sophisticated as its interior is emotion-evoking. The 4.0 TFSI, which is installed in the engine compartment like a technical masterpiece, produces 605 PS and 700 Nm (516.3 lb-ft) of torque; in overboost mode, which the driver can call up for around 15 seconds, a boosted torque of 750 Nm (553.2 lb-ft) is available. The sonorous biturbo V8 accelerates the two-door coupe, which has an unladen weight of 1,980 kilograms (4365.2 lb) from 0 to 62 mph in 3.7 seconds.

The show car is capable of returning  to 32.8mpg combined, which equates to CO2 emissions of 199 grams per kilometre. One contributor to this high efficiency is a new 48-volt subsystem of the vehicle electrical system – this is a technology that will soon be introduced to production cars at Audi. The 48-volt system is supplied by a powerful belt starter generator, which turns the powertrain into a mild hybrid and has an energy recovery output of up to 12 kW during braking. An eight-speed tiptronic directs engine power to the quattro permanent all-wheel drive, which works closely with torque vectoring.

New five-link wheel suspensions

In the chassis, the adaptive air suspension sport – an air suspension with controlled damping – offers a large adjustment range between smooth rolling and very tight handling; it also varies the show car’s ground clearance over several levels. The front and rear suspensions are engineered as lightweight five-link designs. The large carbon-fibre ceramic brake discs decelerate the show car powerfully. On the 20-inch front brakes, they are gripped by six-piston fixed calipers.

A technology highlight of the Audi prologue is its dynamic all-wheel steering – it boosts driving dynamics and ride comfort by an intelligent combination of dynamic and all-wheel steering. The driver therefore can enjoy an automobile with extremely good handling. In the lower speed range, this is made evident by better agility and turning ability. In the higher speed range, developers improved the car’s responsiveness which leads to greater vehicle stability.

Overall, dynamic all-wheel steering – with rear wheel steering angles of up to five degrees – makes it easy to manoeuvre when parking and offers precise steering on country roads and impressively comfortable steering on freeways.

Fuel consumption of the models named above:

Audi A8:

Combined fuel consumption in l/100 km: 11.3 – 5.9** (20.8 – 39.9 US mpg);

Combined CO2 emissions in g/km: 264 – 144** (424.9 – 231.7 g/mi)

DCI Gene Hunt and Audi join forces to auction iconic ‘Ashes to Ashes’ car for BBC Children in Need

Bids are currently being invited for the famous red Audi ‘Ur quattro’ used as the formidable sidekick to DCI Gene Hunt in the BBC hit drama series Ashes to Ashes. The car will be sold to the highest bidder in an online auction for this year’s BBC Children in Need charity appeal, the highlight of which will be a live televised show airing on BBC1 on the evening of Friday November 14.

The iconic sports car, which is currently owned by the BBC and was famously ‘fired up’ by Hunt in each episode, is a 1983 example featuring a two-valve-per-cylinder version of the legendary turbocharged five-cylinder petrol engine. It has undergone a major restoration by Audi UK to ensure that it looks its very best for this auspicious occasion.

The actor Phil Glenister, who played Hunt, has also added value to this unique mechanical supporting act by personally signing an autograph underneath its bonnet, and as a further reminder of its colourful career on the small screen has also added his character's "fire up the quattro" slogan.  

In an accompanying video specially shot in support of the BBC Children in need fundraising campaign, Glenister also gets behind the wheel and says: "If you want to fire up the quattro, first you have to fire up your wallets!"  

The auction is currently underway at the BBC Children in Need eBay shop, and ends on Sunday November 16 at 2100hrs.

The event has a special significance because the Ur quattro and BBC Children in Need share a 34th birthday: the quattro made its debut at the Geneva Motor Show in 1980, the same year BBC Children in Need was founded.

In a poll held in 2013 by Auto Express magazine, the Ashes to Ashes quattro was voted number four in a list of the top 40 most famous television cars of all time. The model itself became the world’s first large volume all-wheel-drive production car, breaking the mould in engineering terms and ushering in a new era in motorsport spearheaded by legendary World Rally Championship-winning versions. The quattro remains hugely desirable today amongst collectors and enthusiasts.
