750-HP Audi RS7 Shows BMW and Mercedes Who's Boss

Tuning

"The World's Fastest RS7" lives up to its name.

Comparative titles like "the world's fastest" or "most powerful" only remain relevant as long as another, newer and better model doesn't come along. But this modified Audi RS7 Sportback, which claims to be the "world's fastest" thanks to modifications like super-fast shifting transmission and 750 horsepower, certainly manages to prove its point, dragging against powerful opponents like an 860-hp Mercedes CLS63 AMG and an 820-hp BMW M3 and crushing them all the way to finish line.
