A standardAudi RS5 is powered by a turbocharged V8 engine with a total output of 450 HP at 8250 rpm and 317 lb-ft of torque between 4,000 and 6,000 rpm. That’s quite impressive for a luxury sports coupe, but apparently not impressive enough for German tuner, Senner, who believed that the car could do much better than that.
So, with a new valve-controlled stainless steel exhaust system and adjusted zero-pressure monitoring, the output has been increased to 506 HP and 478 NM of torque. With these new numbers the RS5 will sprint from 0 to 60 mph in 4.2 seconds, while top speed has been increased to 173 mph.
Next to the engine upgrade, the tuner is also offering a new Bilstein coilover kit, called the B16 PSS10, that allows for 10-stage adjustable damping, shiny black 245 carbon fabric, additional front grille, and window frames in the Black Edition. The package is finished by a new set of 20" wheels painted in diamond black polish.
