For those who may not know, the standard Audi RS6 is a fairly bonkers car when it comes out of the factory with 560 horsepower and 700 Nm of torque. And it’s an estate car, in case we failed to mention it earlier. Now, Austrian tuner OCT Tuning decided it is actually pathetically weak. And they have the remedy to cure it.

This comes in form of some serous fiddling with the bi-turbo V8 engine which includes the addition of a super sport exhaust system. It boosts the output to an insane 670 horsepower and over 880 Nm of torque.

Now, the Audi RS6 by OCT Tuning is a big and heavy car. Even so, it catapults form 0 to 100 km/h in 3.4 seconds (half a second quicker than standard), and on to a top speed of, now that the Vmax limiter is removed, 300 kph (190 mph) or optionally 320 kph (200 mph) if you fit it with proper tires for the job.

While Oct does nothing to the appearance of the Audi RS6, the sports exhaust system they put on the car gives it a sexier soundtrack and thus more drama. Not that you need any more of it when you have that kind of performance numbers, but still.
