A tuned BMW M5 takes on the Audi RS Avant in Sweden. With a Burger Motorsports ECU tune, AFE air intake and carbon scoops, AMS downpipes and a few other mods, the BMW M5 makes 700 horsepower. A pretty significant increase from the standard 560 hp. The Audi RS6 delivers 690 horsepower, yet heavier due to its all-wheel drive system. The M5 is about 75kg (165 lbs) lighter than the RS6. Are the 10 extra horsepower worth more than the 75 kilos weight difference? Find out on this video.
