The production of the Audi TT started in 1998. This sports car was offered in two-seat roadster and coupé body designs. Both roadster and coupé can be equipped with the traditional Audi’s quattro all-wheel drive. The power unit of the base Audi TT trim makes 211 hp, while the TTS package has the engine that produces 265 hp. The TT badge is taken from the title of the prominent British motorcycle race “Isle of Man TT” where TT means Tourist Trophy. The TT abbreviation may, however, be taken from the word combination "Technology & Tradition".
