Powered by a 4.2-liter naturally aspirated V8 FSI unit, the RS4 made use of 420 PS (414 HP) and 430 Nm (317 lb-ft) of torque in order to hit 100 km/h (62 mph) in just 4.8 seconds, despite weighing a portly 1,725 kg (3,800 lbs). You also had quattro all-wheel drive and a 6-speed manual transmission helping put all that power down, and it all came together for a truly visceral experience.
