The new modification pack brings the car’s supercharged 3.0 liter engine from its factory stock power of 333 hp to a level of 375 hp, while the maximum torque is boosted from 440 Nm to 495 Nm. The power and torque premium has been achieved through the installing of an ECU remap and a high-flow sports air filter. The tuner has also fitted a stainless steel exhaust system, that features sport catalytic converters and a four pipe muffler. This allows the powerplant to “breathe” more easily and offers a distinct sound.
In addition to that, the tuner has removed the top speed limiter that paused the car’s acceleration when the vehicle reached 250 km/h.
The vehicle uses a lowered suspension, which reduces the front ride height by 40 mm and the rear ride height by 35 mm. The S5 Sportback rides in T1S Work VARA Diamont two-piece alloy rims, which come in a 20 inch size and feature a two tone finish. The wheels are wrapped in 245/30 R20 (front axle) and 295/25 R20 high performance tires.
The interior of the vehicle has not been neglected, as the tuning house has upgraded it with new tachometers as well as with new trimmings that use a carbon fiber finish.
Senner tuning has not announced the pricing of the Audi S5 Sportback Grand Prix modification kit.
