This Tuned Audi RS6 Avant Is Way Cooler Than An SUV

These are increases of 184 hp and 169 lb-ft over the stock output, resulting in insane performance from this hot station wagon. After the dyno test, MTM ran some preliminary performance tests where the ran hit 62 mph in 3.1 seconds and 124 mph in 9.8 seconds. We have a feeling that with the right driver on a prepped surface, the MTM RS6 will easily crack into the two-second range on its 0-60 mph run. MTM says these quoted figures are the company's "conservative estimates" and the car could potentially go even faster.

MTM offers its Audi RS6 C8 Performance Upgrade (an ECU tuned) for $2,599, M-Cantronic Generation II (an increase to 722 hp) for $2,699, or the full ECU conversion stage 1 for $11,999. That last option brings the power up to the full 776 hp out with a new air filter, air intake, turbo inlet, speed limiter, and optimized TCU communication (gearbox).

MTM is no stranger to making Audis faster, having tuned each of the RS6's previous generations. The original RS6 was only sold as a sedan in the US (but offered as a wagon in Europe), packing a 4.2-liter twin-turbo V8 producing 450 hp. For the second generation, Audi dropped in a twin-turbo version of the Lamborghini Gallardo's 5.0-liter V10, offering a massive jump in output to 571 hp. The third generation dropped back down to eight cylinders now displacing 4.0-liters but raising output to 596 hp in the Performance version. This latest generation model is by far the most visually exciting of the bunch and it will only get better once tuners like MTM work their magic on it.
