Audi does not use DSG. DSG is used by Volkswagen's transverse engine. There are two types of Audi's S Tronic. Some are transverse engines and their structures are similar to DSG. The TTS you are talking about It is this gearbox, and high-end models such as the RS series and S series as well as the high-end 50TFSI of the new A6L and other new generation models that require more sportiness all come with Audi's signature S Tronic, which is installed vertically. Much better location! The general distinction can be seen from the gear position. The requirements for the horizontal position are not too high, so the number of gears is not too many, and the number of gears is about the same as 6, while the vertical position requires more high-end sports, at least 7 or more.
