Here is Specs of 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 RS6 is a car without equal. Following on the heels of the Audi RS6 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 RS6 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 RS6 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.
The engine's power flows through the six-speed tiptronic, one of a new, dynamic generation of Audi automatic transmissions. Its reaction time has been reduced to one tenth of a second, shift time has been halved compared to units used in other models and transmission ratios are short. The driver can also manually change gears either using the shift lever or the paddles on the steering wheel. The tiptronic transmission transfers the power to an extremely sporty, rear-weighted quattro drive train.
