Tuning firm Senner Tuning have brought out a new tuning package for the Audi S5 Sportback just a few months back. The package named Grand Prix has modifications that would alter the looks of the Audi both internally and externally and that include the engine too.
The standard S5 Sportback has a 3.0 liter V6 engine which gives an output of 333 hp and torque of 324 lb-ft. The Grand Prix tuning kit now adds an ECU remap as also a high flow sports filter. A new exhaust system of stainless steel and sports catalytic convertor has also been added. It ends with a four pipe muffler, and all this to add more power to the existing engine. Post modification the engine delivers 375 hp with peak torque of 495 Nm. The top speed also has been raised but the exact details are not yet known. Suffice to say that it would be above the previous speeds of 155 mph.
The tuning kit also lowers the suspension so that the front ride height of the car is now down by 40 mm while the rear ride height is lowered by 35 mm. Wheels that come with this tuning package are two piece allow wheels of 20 inch dimensions.
The interior modifications include carbon fiber trimmings and new tachometers. With these changes the price would naturally be a changed factor which though is yet to be disclosed.
