At the 42nd Annual Meeting of Stockholders of Volkswagen AG in Hamburg, the most economical car in the world is presented: the 1-litre car. The prototype, which until now has been kept closely under wraps, and which may people never believed could be built, was driven under its own power from Wolfsburg to the Annual Meeting in Hamburg. Before the Annual Meeting, the current Chairman of the Board of Management, Dr. Ferdinand Piëch, drove this research vehicle to Hamburg from the company's headquarters at an average fuel consumption of 0.89 litres per 100 kilometres. This has once against impressively demonstrated Volkswagen's position at the cutting edge of modern technology.
The objective of developing a roadworthy vehicle that consumes just 1.0 litre of fuel per 100 kilometres could not be achieved through compromise. All existing technical solutions were examined, and in close cooperation with numerous suppliers, replaced by better, and principally lighter versions. The result is a vehicle that looks more like a sports car than a typical research vehicle.

The conceptual necessity for a small frontal area led to an unusually narrow and very flat body form being chosen. The body was developed in a wind tunnel, is 3.47 metres long, but just 1.25 metres wide and just over a metre in height, and is made completely of carbon fibre composites. To save weight, it is of course not painted. The carbon-fibre-reinforced outer skin is tensioned over a spaceframe that is not made of aluminium, but rather of magnesium, which is even lighter.

The 1-litre car is powered by a one-cylinder diesel engine, centrally positioned in front of the rear axle and combined with an automated direct shift gearbox. The crankcase and cylinder head of the 0.3-litre engine are of an aluminium monobloc construction. The naturally aspirated, direct-injection diesel engine employs advanced high-pressure unit injection technology to generate 6.3 kW (8.5 bhp) at 4,000 rpm. This gives the vehicle, which weights just 290 kg, an astonishingly lively temperament.

Fuel consumption is a mere 0.99 litre per 100 kilometres. With a 6.5-litre tank, this gives a range of some 650 kilometres without refuelling.

Due to the restriction of space, it was not possible to adapt an existing gearbox. For this reason, a compact, automated 6-speed gearbox is employed, which is controlled from a turn switch in the cockpit.

Running gear made of lightweight alloy, tyres that offer optimised rolling resistance and 16-inch wheels made of extremely lightweight composite material perfectly complement the economical drive system.

The interior is sportingly simple in design, yet offers enough space for two people, who can comfortably get in after folding back the turret-like gullwing door. An extremely lightweight construction has also been employed for the seats. The seat frames are made of magnesium, and firm, yet comfortable fabric covers are used instead of a classic upholstery.

Despite the lightweight construction of all components, safety has been a major element in all phases of the development of the 1-litre car. For example, the concept vehicle's safety equipment includes anti-lock brakes, ESP electronic stability program and a driver's airbag. Deformation elements at the front end and the spaceframe construction provide impact and roll-over protection comparable to that of a GT racing car.

The sports-car-like design demonstrates that Volkswagen's 1-litre car is not a spartan research vehicle, but a high-tech special vehicle. It starts with the special seating arrangement. The driver and passenger sit centrally as if in a monoposto, but in tandem. The mid-engine is installed transversely in front of the rear axle. With its complex design (double wishbones at front, DeDion suspension at rear) and combined with the low centre of gravity and low overall vehicle weight, the lightweight running gear results in very agile handling.

The project team have impressively succeeded in combining driving pleasure with a level of fuel consumption never seen before.

The 1-litre car also incorporates numerous details of a practical and convenient nature. For example, there is an easily accessible stowage compartment with a capacity of 80 litres under a separate flap in the rear; a reversing camera that helps when manoeuvring; automatic locking/unlocking of the gullwing door and a starter button in the cockpit that together allow keyless operation.

The concept of the 1-litre car - four wheels, low height, with two seats in tandem - gives an idea for a possible new family of vehicles, which could cover new requirements ranging from the ultra-economical vehicle, through the low-lost everyday touring vehicle for young people to the high-performance sports supercarUnderneath the hood of the two S6 models, the saloon and the Avant, a 4.2-litre V8 engine with five valves per cylinder goes about its work. Its power output has been increased to 250 kW (340 bhp). The power flow from this eight-cylinder engine is impressive, with a torque of 300 Nm available only slightly above idle speed, rising to a maximum torque of 420 Nm at 3400 rpm. Top speed is electronically governed to 250 km/h. The S6 sprints from 0 to 100 km/h in 6.7 seconds and the S6 Avant in 6.8 seconds.

A 5-speed tiptronic transmission with ratios chosen to suit the car's sporting character delivers power to the quattro permanent four-wheel drive, which in turn transmits it with supreme reliability to the road. A direct steering ratio ensures particularly agile and precise response to steering wheel movements. Active safety is further enhanced by the Electronic Stability Program ESP.

The design of the Audi S6 communicates its dynamic character. Based on the most powerful Audi A6, the 4.2 quattro, the S6 nonetheless creates its own individual visual effect thanks to boldly styled grilles.

The flared wheel arches accommodate 17-inch cast aluminium wheels of Avus design with 255/40 R 17Y tyres. Polished aluminium outside mirror casings, two visible stainless steel exhaust tailpipes, and bumpers and side sills painted entirely in the body colour create additional visual accents.

With Recaro sports seats in a combination of Alcantara and leather, a leather-covered sports steering wheel, an Alcantara headlining and carbon-fibre trim on the instrument panel and door linings, the interior too lives up to the high expectations of customers in the top sporting segment.
