The New 2009 Audi RS6

426 kW (580 hp) and 650 Nm (479.42 lb-ft) of torque
- with its twin-turbo V10 and quattro permanent all-wheel drive, the
Audi RS 6 is a car without equal. Following on the heels of the RS 6
Avant, Audi now presents the sedan. It drives like a supercar thanks to
its superior performance and thrilling dynamics, yet offers all of the
everyday utility of a large business sedan.

The engine of the new Audi RS 6 is a
high-tech work of art. The 4,991 cc V10 bundles a number of Audi's
race-winning technologies - FSI direct fuel injection, dry-sump
lubrication and two turbochargers. With up to 1.6 bar of boost
pressure, these provide smooth, powerful thrust and an incomparable
power band: The peak torque of 650 Nm (479.42 lb-ft) is available from
1,500 to 6,250 rpm and thus nearly over the entire rev range. Peak
power of 426 kW (580 hp) is generated between 6,250 rpm and the maximum
figure of 6,700 rpm.

With a power-to-weight ratio of 3.4
kilograms per hp, the Audi RS 6 performs like a supercar. It catapults
to 100 km/h (62.14 mph) in 4.5 seconds on its way to an
electronically-limited top speed of 250 km/h (155.34 mph), which can be
optionally raised to 280 km/h (173.98 mph). The V10 responds
immediately and spontaneously to the throttle, and is very smooth while
accelerating with a powerful roar.
