The current AUDI RS6 already boasts an impressive engine performance but an enhanced version from Reifen Koch will likely impress any fan out there. This vehicle can be driven legally on the road but it’s very capable of entering a race. The RS6 had its software optimized and it also got a sport air cleaner and a sport exhaust system. From 580 hp, the modified RS6 now is capable of delivering 700 hp. The maximum torque is at 790 Nm (standard version delivers 650 Nm) and the top speed is claimed to be about 330 km/h or 205 mph. Aside from improving its performance, this vehicle also gets some cosmetic tweaks. It received a Schmidt wheel set with a 22-inch wheel/tire combination. Buyers may also opt for the Schmidt Revolution CC LINE light alloy wheels with polished external bed that measures not less than 10×22 inch. These fill out the wheel housings with high speed tires that are sized 265/30 22. This vehicle also gets the AUDI carbon high speed brake assembly.
