The version that they revealed now is a TT RS with 739 hp and 648 lb-ft of torque achieved with the help of a GTX35 turbocharger, 90mm Clubsport exhaust and new intercooler.
This small but extremely powerful sports car is sold for $53,308 which is close to the price of a stock TT. If you don’t want to spend $53k on tuning, you can opt for a $10,660 turbo kit that boost the horsepower to 592.
