RENNtech AMG GT S & RENN TAXI Audi R8 GT vs. Porsche GT4 Nordschleife//.

Fun lap following the CEO of RENNtech Europe driving the RENNtech tuned Mercedes-AMG GT-S Edition 1with over 600 bhp. We also pass another interesting renn car but this one is a Audi R8 GT from RENN Taxi giving a fast taxi lap.
