The RS4 is by no means inconspicuous ex works, and whoever puts it next to a 2.0 engine will also find that it is definitely not "quiet". ABT sees it completely differently and gives the noble vice some effective changes.

What the RS4 certainly does not need are mighty front aprons, side skirts, etc. That is exactly what it brings with us from the factory - it is optically perfect. This is exactly what ABT thought and therefore focused on the sound and other components. Since the RS4, like all RS models, works at 250km / h, ABT was the first to address this issue. You have removed the V-Max and let the station wagon run free, it only ends at 290km / h. So that you can also hear that an "RS" is coming, ABT has given the high-speed V8 a full exhaust system that is soundproof.
The original RS rims have also been replaced by new 20-inch turbine blade-look rims with 25mm spacers each, which leave the wheels much more solid in the wheel arch.
