The latest Audi RS6 is widely regarded as not only the finest RS Audi ever, but also the best super wagon in the world. It has just the right blend of power, luxury and beauty. The only thing not so good about the RS6 is its interior, which is typical Audi: great fit and finish, but to dark and dull.

That is why the owner of this RS6 sent his car to Vilner, an authority in interior upgrade in Europe. The Bulgarian tuner decided the best approach, given the character of the car, is to steer clear of their usual over the top style, and settle for something more sober and dignified.

So they swapped the headliner with a custom one made from black nubuck, and treated the plastic bits to a nice coat of black as well. The pièce de résistance is a set of racing blue seat belts to complement the unique white leather seats. These rather simple changes lift up the cabin and make it a much nicer place to spend time in.

The interior treatment also suits the exterior looks of the Audi RS6, and also its inner power. The standard RS6 with its 560-hp TFSI V8 is brutally quick, but this one has been treated to a software upgrade by RaceChip Germany which bumps the power up to 700 hp and 889 Nm of torque. It is now dangerously fast!
