German tuner MTM has a long history with Audi’s inline-five. In fact, company founder Roland Mayer helped develop the turbocharged five-banger for the Sport Quattro back in the mid-80s, and MTM produced a 400 horsepower version of the motor as one of their earliest performance packages. Nearly 20 years later the technology and the cars have changed, but MTM is still doing its thing.
Its latest project is Audi’s TT RS, which boasts 340 horsepower and 332 lb-ft torque in stock trim. MTM is offering three stages of engine packages ranging from 404 to 424 horsepower courtesy of tweaks to the engine control unit and and an upgraded exhaust system. Naturally, the Stage Three kit provides a substantial boost performance, including a top speed of 185 mph and a 0-100 km/h time of just 4.2 seconds. A variety of other upgrades are available as well, including MTM’s 19-inch Bimoto wheels, 15-inch brakes with eight-piston calipers, and lowering springs.
