RENNtech took on one of the rarer Mercedes-Benz, the brand-new 2016 - S 65 AMG Coupe. Equipped with AMG’s 6.0L V12-BiTurbo engine, RENNtech upgraded the ECU and the exhaust to bring this already breathtaking car to astonishing 600whp and 744wtq. The stainless steel sport muffler adds the unique RENNtech sound, to make sure no one will forget the sound of this monster after it flew by.
