A heavily modified twin-turbo Audi R8 by Underground Racing was the king at a recent drag racing event.
Upon first sight, this might look like an ordinary first generation R8 GT riding on Toyo R888 street tires but hiding underneath the stock appearance is a beast since the V10 5.2-liter engine is no longer naturally aspirated. The engineers form Underground Racing fitted a twin turbocharger system which has boosted the total output to a whopping 2,100 bhp which likely makes it the most powerful R8 in the world.
It should be mentioned that while the stock Audi R8 GT has an R-Tronic automated manual transmission, this heavily modified version comes with a sequential gearbox better tailored for drag racing.
The car participated recently at the Texas Invitational Fall 2015 event and managed to hit a top speed of 213 mph (343 km/h). It faced some pretty stiff competition, including a 1,100 bhp Chevrolet Corvette ZR1, a 1,500 bhp twin-turbo Corvette, 2,100 bhp twin-turbo Lamborghini Gallardo and a mighty 2,200 bhp Nissan GT-R that had race-spec tires. It took the win in all races, although it was very close with the GT-R but ultimately the twin-turbo Audi R8 from Underground Racing managed to triumph.
