ABT Sportsline Audi TT-RS An ABT TT-RS is therefore able to keep up with the quickest of the quick at all times or even pass them by. Precisely what the ur-Quattro from ABT was also able to do. There is, however, one difference between then and now: contrary to the classic from the 80s the TT-RS is not just available as a sports coupe, but also as a cool roadster.
