2009 Audi RS 6

(Credit: Audi) The new Audi RS 6 Sedan has launched itself to the very top of the business class – as the most powerful series-production sedan in its segment. The sporty tiptronic transmission and the quattro all-wheel drive system, which has a slightly rear-driven emphasis, transfer the immense power onto the road with no loss.

Producing 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.

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.
