The new Audi RS6 Avant is powered by a twin-turbocharged, 4.0-liter, V-8 engine that delivers a total of 560 horsepower, making it one of the most powerful sports wagons out there. Even the best can be better sometime, so the German tuner O.CT Tuning found a solution to improve this output even further.
The tuner is offering two stages of upgrades for the RS6 . In Stage 1, the engine electronics are heavily modified, pushing the V-8 engine to a blistering 670 horsepower and a peak torque of 649 pound-feet.
With the extra 110 horsepower under the hood, the RS6 awakens to a tune of 0 to 60 in 3.4 second. Top speed is increased to 190 mph, but an optional set of tires allow O.CT to unharness the RS6 to a top speed of 200 mph.
A Stage 2 upgrade is also available, and it includes an additional sports exhaust system that adds another 10 horsepower to the output level delivered by stage 1.
