This must be the MOST bonkers Audi S1 replica build EVER!
I just can't get enough of that 5-cylinder sound! #audi #quattro #s1 #hillclimb #sound #5cylinder
This is hands down one of the most bonkers Audi S1 replica builds going! It's the Audi Sport Quattro S1 Group B replica tuned by Prospeed Motorsport and driven by the Bulgarian driver Nikolay Zlatkov. This hillclimb monster is powered by a 5-cylinder turbo engine which is able to produce a whopping 770 horsepower!
