Senner Tuning has prepared a second performance package for the new Audi RS5, and as you might suspect, the power level on the German coupe has been further increased.
This means that instead of 450 HP (331 kW) and 430 Nm resulted from their previous upgrade, the Senner Audi RS5 is now able to deliver 506 HP (372 kW) and 478 Nm of torque, due to its new valve-controlled stainless steel exhaust system with zero-pressure monitoring.
These new output figures enable the Senner Audi RS5 to sprint from 0 to 100 Km/h in 4.2 seconds and reach a top speed of 300 Km/h. 
At the exterior the Senner Audi RS5 has been enhanced with a new set of 20 inch, diamond black polished alloys wrapped in performance tires, carbon fabric mirror cases plus additional front grille and window frames. Optional carbon fiber and leather interior customisation is also available.
The Senner Audi RS5 price is around 113,900 Euro, which means 18,900 Euro more than the stock version.

of the model. And as Benno Senner never leaves things to chance, there
was not an unexpected result.
The Bilstein coilover kit, called B16 PSS10, allows for 10-stage
adjustable damping in both the compression and rebound cycles. For the
demonstration purposes, different left and right rims of the vehicle
were coated with respective coating: diamond black polish in dimensions
of 9.5 x 20 inch at the front and 11×20-inch at the rear. Driver side

250 km / h, now provides 372 kW / 506 hp / 478 Nm and a sprint from 0 to
100 km / h in 4.2 seconds. The maximum speed limit has been raised to
280 km / h. It is possible to reach even 300 km / h, of course, only
with changed tires.

shiny black 245 carbon fabric, additional front grille and window frames
in the Black Edition. With regard to the electronics, it should be
