Above 3,000 RPM, the exhaust valves can be commanded fully open to enhance the engine's sound and power delivery. APR has also introduced a subtle exhaust crackle inspired by previous RS3 models.

-
Increased stationary rev limit to 5,500 RPM

The calibration improves turbocharger control, boost management, thermal protection and fuel-system operation while delivering smoother throttle response and a stronger, more linear power curve.
The result is a more responsive RS3 with increased power throughout the rev range and improved confidence when driving under demanding conditions.
