Almost the entire engine range of the Audi Group is produced by AUDI HUNGARIA MOTOR Kft, and it also supplies the Volkswagen, Seat and Skoda brands with engines as well. The mechanical processing of the five main engine components of the various engine types, the camshaft, the crankshaft, the cylinder-head, the crankcase and the crank-rod is also done locally. Audi Hungaria is the sole factory in the world where the Audi TT sports cars are assembled in the framework of the cooperative production between Győr and Ingolstadt.
