Bulgarian interior specialists from Vilner have recently finished working on an Audi RS6 Avant.

As expected from Vilner, all the work has been put into the cabin where the ceiling has been wrapped around in black nubuck (top-grain cattle leather with a velvety surface) also noticeable on the rearview mirror. The plastic bits and pieces have been covered with a rubber-like material finished in black while the seat belts now have a racing blue look to complement the body paint.

RaceChip Germany was in charge of tweaking the V8 4.0-liter twin-turbo engine and they managed to bump output from 560 HP (412 kW) and 700 Nm (516 lb-ft) to 700 HP (515 kW) and a massive 889 Nm (655 lb-ft) of torque.

There's no word about performances but it should be a tad quicker than the standard RS6 Avant which needs 3.9 seconds until 62 mph (100 km/h) and tops out at an electronically-limited 155 mph (250 km/h) or 190 mph (305 km/h) when configured with the optional Dynamic plus package.
