Audi S5 Sportback Grand Prix with 375HP by Senner Tuning

The Grand Prix is Senner Tuning's take on the new Audi S5 Sportback. Starting with the engine, the German company brings output from the standard 3.0-liter TSI's 333 horsepower and 440Nm /325 lb-ft of torque to 375HP and 495Nm / 365 lb-ft. The power boost comes from a reconfigured ECU, the addition of a performance air filter as well as a custom sport exhaust system with four tail pipes.
