Underground Racing introduces to you the very first Twin Turbo Audi Gen 2 2019 R8+. Preliminary testing has been a great success. Driving an Underground Racing TT R8+ is something that should only be experienced, not explained. Pulling away on launch control with the 7 Speed LDF dual-clutch transmission and the help of some boost which is controlled via our proprietary JRR MoTeC M1 electronics and firmware with the additional horsepower is just that, an experience.
