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.
The S5 Sportback Gran Prix also gets a set of sport springs that lower the ride height by up to 40mm or 1.58-inches and new two-piece 20-inch alloy wheels shod in 245/30 R20 tires up front and 295/25 R20 at the back.
Finally, the Audi's interior is revamped with a carbon fiber trim package.
