Audi S8 already in the 10's tune only - 1/4 mile comparison video between stock, APR Stage I 93 octane tune, and APR 100 octane race gas tune
Wow. Quite simply, wow. The 4.0 TFSI is a potent motor as we have all seen. Audi uses this motor in a variety of levels of tune from the standard S6, to RS6, to S8. In the S8 the motor features larger turbos that can produce a bit more power than in the S6
as these 1/4 mile results from APR show. The car is no slouch in stock form capable of 11's in the 1/4 mile at 116 miles per hour despite its fairly hefty curb weight of 4620 pounds
What happens to the 1/4 mile time once tuned? Well an APR tune on 93 octane improves the numbers to firstname.lastname@example.org. That would be low 11's in a luxury sedan with just a tune. What happens on 100 octane race gas with a race tune? email@example.com.
You could pull up next a Porsche 911, C7 Corvette, BMW M5, etc., and have three of your friends help you wave goodbye. If APR upgrades the turbos on this car the sky is the limit.
Incredible results, congratulations to APR who is doing great things with the 4.0 TFSI platform.
