Wettstetten/Ingolstadt-based Audi tuning and refining company MTM announces that it can break the 300 km/h with less than 500 horsepower, using the Audi TT RS. This seems a very difficult job for most tuners. What MTM does is it modifies the vehicle’s electronic control unit and equips it with MTM’s own turbocharger and a whole new set of MTM exhaust system. The tuning company’s aim is to increase driving dynamics, acceleration and maximum speed.

And the result is incredible. The refined Audi TT RS achieves 472 horsepower with 7000 rpm, accelerates 0-100km/h in just under 4 seconds coupled with a top speed of 312 km/h. It is worth noting that the standard Audi TT RS has a 2.5 liter inline-5 engine. As for the wheels, MTM has replaced the standard with Dunlop Sport Maxx tires. The tuned vehicle achieves 188.8 horsepower per liter. Costs for this MTM upgrade get quite pricey.
