The automotive market has evolved to the point where carmakers offer a wide range of intermediate versions of their vehicles. Can’t afford a BMW M but you also want something above the standard model? You can get one with the M Sport package. The same goes for various Mercedes-Benz models and, starting 2017, for a couple of Audi vehicles too. The German firm has just launched the Audi Sport Performance Parts line, which adds various upgrades to the R8, TT, TTS and TT RS.
