ABT Sportsline has treaded carefully with its tune for Audi's super-wagon offering some mild performance and styling upgrades.
While the company leaves the RS4 Avant's 450PS (444bhp) 4.2-liter naturally-breathing V8 untouched, it removes the 250km/h (155mph) electronic speed limiter allowing the estate to reach a maximum velocity of 290km/h (180mph).
It also replaces the stock exhaust system with a new stainless-steel unit that provides a "loader roar", as stated by ABT itself.
A new set of 20-inch two-tone alloy wheels that work together with 25mm spacers on each side, along with custom boot and floor mats, complete the German company's offerings for the RS4 Avant.
