German tuner MTM has launched an upgrade program for the 2012 Audi S6 which brings a power increase and other improvements.
MTM is no stranger when it comes to aftermarket kits for Audi models as in the last few years they've come up with upgrade packages for the previous RS6, A1 and S5, just to name a few. Their latest project is based on the most recent S6 fitted with the 4.0-liter, twin-turbo V8 TFSI engine which as standard produces 420 HP (309 kW) and 550 Nm (405 lb-ft).
By ECU remapping and making several engine modifications, the power unit is now capable of developing 555 HP (408 kW) and 700 Nm (516 lb-ft), enough for a 0-62 mph (0-100 km/h) time in 4.2 seconds (0.6s faster) and a top speed of 180 mph (290 km/h), unlike the stock car which is electronically-limited to 155 mph (250 km/h).
Other parts available include MTM Bimoto nine-spoke alloys, custom suspension and a new brake kit with Brembo components. The power boost costs 3,791 EUR, while the suspension kit will set you back an additional 1,737 EUR.
