1992 Audi S4 IMSA GTO 5-Cylinder 720HP Turbo Engine SOUND!!

During the Goodwood Festival of Speed 2017 I had the pleasure to film this gorgeous 1992 Audi S4 IMSA GTO. This beast is powered by a 2.2 liter inline-5 turbocharged engine which is able to produce more than 700 horsepower. The sound it makes is absolutely amazing, especially when it upshifts!
