Tuned: 400 AWHP Supercharged Audi RS4

The B7 Audi RS4 is one of the best sports saloons ever built. It features a 4.2 liter V8 engine sending power to all four wheels via Audi’s highly acclaimed Quattro AWD system. So to make it better, it only makes sense to go for forced induction. This is what Matthew Collins from Aurora, Colorado has done to his RS4, first featured in EuroTuner magazine. With a PES supercharger kit, the RS4 makes 400 horsepower at all four wheels. This is enough to sprint the four-door saloon from 0-100 kph (62 mph) in under 4 seconds. Rolling on a set of 20 inch HRE 893R wheels, the RS4 can’t look any better this.
