April 2008 is the month to keep an eye on, because that will signify the showroom launch of the new Audi RS 6 Avant, Audi's most potent car ever (not counting the Audi R10 TDI LaMans racer). Audi's new family sports wagon produces an astounding 580 hp (426 kW) from a newly developed V10 FSI engine with torque peaking at 650 Nm at 6700 rpm. The new TwinTurbo V10 FSI is based on the V10 found in the S6 and S8 but has been redeveloped in almost every single aspect to attain this new level of performance.
Needless to say that its performance times are impressive and comparible to super cars. 0-100 km/h takes just 4.6 seconds and 0-200 km/h in just 14.9 seconds with and only stops at 250 km/h because of its speed limiter. And while the car weighs in at 2,025 kg, the power-to-weight ratio is just 3.5 kg to every horsepower. A six-speed tiptronic is putting all that power to the road through Audi's quattro four-wheel-drive system.
The interior is of Audi quality with carbon fibre, aluminium, leather and Alcantara with the usual safety features as standard. Wheels come in 19 inch as standard but 20 inch are optionally available. Audi has fitted ceramic brakes on 420mm steel discs in the front and 356mm in the rear.
Outstanding top performance and maximum dynamism combined with excellent suitability for everyday use are the impressive features of the new Audi RS 6 Avant, which will be unveiled to the public for the first time at the IAA 2007 in Frankfurt. A newly developed V10 engine with FSI direct injection and twin turbochargers, permanent quattro four-wheel drive and sports suspension with Dynamic Ride Control DRC set the standard for high-performance vehicles in the luxury class. 426 kW (580 bhp) and a maximum torque of 650 Nm add up to an unforgettable performance experience. At the same time, the new Audi RS 6 Avant offers a high standard of travel comfort – on long journeys, too.
The Audi RS models from quattro GmbH are the ultimate in sportiness, complemented by powerful and elegant design, exclusive equipment and perfect quality. It has also meanwhile become a good tradition that their sports performance is combined with the high utility value of an Avant: the very first Audi RS2, which appeared in 1993, was only built as an Avant model. Although the unique Audi RS driving sensation can now be experienced in saloon, Avant and Cabriolet models – as is the case with the current RS 4 – customers especially appreciate the combination of dynamism and versatility that an Avant offers.
The new Audi RS 6 will therefore only be available as an Avant to start with, with the unrivalled combination of 580 bhp and a maximum 1,660 litres of luggage space. The Audi RS 6 Avant will be launched in April 2008.The new leader in the performance category
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 – with 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, with 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 with an overall length of 670 millimetres and is very light with 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 with 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 with 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 with 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 with refinement, as is typical of a ten-cylinder unit. When accelerating, of course, its dual-branch exhaust system with 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.
