The all new Audi RS5 has received a tuning kit from the guys at Senner, consisting of performance upgrades, new wheels, suspension, and exterior mods. Under the hood, the powerful 4.2-liter V8 FSI engine was boosted to 506 PS and 478 Nm of torque. This increase of power comes from a valve-controlled stainless steel exhaust system, and adjustments to the zero-pressure monitoring system. The top speed limiter was modified to allow 280 km/h, but without it the Audi RS5 can easily top 300 km/h with a 0 to 100 km/h sprint time of 4.2 seconds. Suspension and styling improvements came next.
