The world’s fastest wagon has just gotten faster.
German tuning firm O.CT Tuning is offering a pair of upgrade packages for the already-lethal Audi RS6 Avant. By simply reprogramming the ECU, output of the world’s fastest wagon is boosted from 560 horsepower and 516 pound-feet of torque to 670 hp and 649 lb-ft. The result is a new 0-62 mph time of 3.4 seconds, down from 3.9, while top speed can be delimited to either 190 or 200 mph. A stage 2 program adds a sports exhaust system for an additional 10 hp of output.
