The new Audi RS 6 Avant: High performance at a new level

The Audi RS 6 redefines the term 'high performance' in the business class. With its 426 kW (580 bhp), it is the most powerful model in the current Audi range and – wîth the exception of pure racing cars like the Le Mans-winning Audi R10 TDI – the most potent Audi of all time. But not only that: it is also clearly superior to all competitors in the top performance category.

The ten-cylinder V-configuration engine in the RS 6 is based on the V10 powerplants of the Audi S6 and Audi S8, but has been redeveloped in practically every respect to attain the significantly higher level of performance. The twin turbochargers ensure an impressively constant stream of power over the entire engine speed range: the mighty peak torque of 650 Nm is available across the entire range from 1,500 to 6,250 rpm; maximum output is available between 6,250 and 6,700 rpm.

The road performance of a super sports car

This powerplant enables the Audi RS 6 Avant to achieve the road performance of a high-performance sports car. It requires just 4.6 seconds for the sprint from a standing start to 100 km/h, and reaches the 200 km/h mark in a mere 14.9 seconds. Only when the needle touches 250 km/h is the propulsive power electronically governed. The power-to-weight ratio, too, matches that of a first-rate sports car: after all, wîth a vehicle weight of 2,025 kilograms – including the dynamic and sure-footed quattro four-wheel drive – every horsepower of the RS 6 Avant has to propel just 3.5 kilograms

The ten-cylinder concept provides the ideal basis for a high-performance unit of this calibre. The V10 is unusually compact wîth an overall length of 670 millimetres and is very light wîth a total weight of 278 kilograms. TFSI technology from Audi, the combination of direct injection and turbocharging, ensures efficient power output, based on extensive experience in the field of motor sport: the R8 racing car, a pioneer of TFSI technology, captured a series of victories for the brand wîth the four rings at Le Mans.

Racing technology for high efficiency

FSI direct injection delivers precisely metered amounts of fuel into the combustion chambers at a pressure of up to 120 bar. This permits a compression ratio of 10.5:1, which is very high for a turbo engine. Remarkably efficient combustion is the result. The engine is thus content wîth a standard consumption of 13.9 litres – a very good figure in view of the potential offered.

A further feature adopted from racing technology is the dry-sump lubrication system used on the V10. By virtue of the elaborate design of the oil pump module and oil tank, reliable lubrication of all engine components and both turbochargers is guaranteed, even wîth constant lateral acceleration of 1.2 g.

Thanks to FSI technology and the optimised design of the turbocharger and air ducts, the ten-cylinder unit is extremely responsive and converts minimum movements of the throttle into dynamic acceleration. Yet the twin turbo is by no means a rough-and-ready sports engine: it runs smoothly and wîth refinement, as is typical of a ten-cylinder unit. When accelerating, of course, its dual-branch exhaust system wîth two oval tailpipes produces that sonorous sporty, throaty sound – an essential feature of a high-performance automobile. Those who wish to enhance this daily delight for the ears even further may opt for the alternative sports exhaust system.

tiptronic wîth exceptionally short shift times

The six-speed tiptronic is the perfect complement to the self-confident, powerful character of the RS 6. Its hydraulics and control system have been optimised to achieve exceptionally short shift times; the ratios have been adapted accordingly. It goes without saying that the new RS 6 transmits its tremendous power to the road via quattro permanent four-wheel drive. The latest generation not only provides substantially more driving safety and stability than a vehicle wîth rear-wheel drive, it also underscores the distinctly dynamic character of the RS 6.

In its basic setting, the centre differential distributes 40 percent of the power to the front and 60 percent to the rear wheels – this slightly rear-biased setup produces particularly dynamic handling characteristics.

Suspension for performance and comfort

The suspension of the Audi RS 6 has been consistently designed for maximum dynamic performance along wîth good travelling comfort – on long journeys, too. Shock absorber and spring settings as well as the entire elastokinematics of the four-link front suspension and the trapezoidal-link rear suspension have been adapted to the new level of performance. The characteristics of the servotronic speed-dependent power assistance have also been retuned. The §teering is consequently very sensitive and delivers optimum feedback from the road.

All in all, in terms of driving feel the RS 6 combines the precision and cornering ability of a sports car wîth the relaxed straight-line stability of a comfortable cruiser. The standard Dynamic Ride Control DRC, familiar from the current RS 4 and consistently enhanced, plays a major role here. This system reduces pitching and rolling movements about the longitudinal and transverse axis of the vehicle in a particularly ingenious way – entirely without the aid of electronics and solely according to the laws of fluid dynamics.
