The German tuning firm MTM has released the official details about their upgrade package for the Audi TT-RS sports car. Inspired by the Ur-Quattro S1 from Group B rally racing, the MTM TT-RS combines a powerful turbocharged five cylinder engine with Audi's patented Quattro all wheel drive system to create a compact tuner car that is capable of besting even R8->ke1440 super car owners.

MTM is offering the power package in three different stages. The top of the line upgrade gives the lightweight four wheel drive a total of 424 HP, 84 more ponies then from the factory. This level of output allows the TT-RS to sprint from 0 to 60 MPH in four seconds and reach a top speed of 184 MPH. The other to packages offer TT owners either 404 HP or 408 HP, now we aren't quite sure as to what makes up the 4 HP difference between the two, and MTM wasn't getting into the specifics. Rounding out the upgrade package, MTM has also fitted the TT-RS with a set of their signature BIMOTO sport rims available in either 19 or 20 inch diameters as well a variety of spacers to get the car's stance just right. No matter which combination of power and style you choose, it will take a very exotic 5.2 Liter V10 for any other Audi to come close to the level of performance available from this MTM modified TT-RS.

It is still being good for best lap timing: the MTM Ur-Quattro S1, with its 5 cylinders engine, has once again shown this summer that it gets around the Hockenheimring almost as fast as the Porsche Armada. 25 years younger as the legendary S1 and directly from the same development department, the tuning specialist presents the MTM TT-RS with the rebirth of the 5 cylinders engine as perfect motorization for drivers who like their car being suitable for racing. After the MTM power therapy, the sport car from Audi gets a power of 424 BHP and 560 Nm of torque and shows itself with a new aerodynamic which is based on the Ur-Quattro.

The secret: love for details and understanding of the new engine from Audi. In addition to the adjustment of the engine control unit, MTM has also worked on the exhaust system: new middle- and end- pipes with throttle valves. Moreover, an additional pre-pipe with metal catalyser can be built in. The result: a high-revving engine, lots of torque in every range of performance and an impressive sound thanks to MTM exhaust system technology with throttle valve. A compact sports car which will be good for best lap times and this not only on the small track of Hockenheim.
