In the video you will see 4 RS6 The fist 2 are stock and the other ones are tuned by MTM and have 730bhp. The second-generation RS6, later called the Audi RS6 5.0 TFSI quattro (Typ 4F) and based on the Volkswagen Group C6 automobile platform, was launched in September 2007 at the Frankfurt Motor Show. With factory production starting in April 2008, it became immediately available in Europe from the same date, and began being exported outside of there in 2009. As of January 2010, it was Audi's single most powerful car ever to be produced by the marque, and positioned the car ahead of its main competitors, the BMW M5 and the Mercedes-Benz E63 AMG in terms of engine output. The RS6's 5.0L V10 biturbo engine produced a maximum motive power output of 426 kilowatts (579 PS; 571 bhp) at 6250 to 6700 rpm, and generated 650 newton metres (479 ft·lbf) of torque from 1500 to 6250 rpm, 52 kW (71 PS; 70 bhp) and 150 N·m (111 ft·lbf) more than BMW's naturally-aspirated 5.0L V10 engine.
