... top speed is already electronically limited, and most people don't have a safe venue for testing it anyway. At lower speeds, aerodynamic drag plays a much smaller role in performance. For example, a 10% increase in air density at 55 MPH would cost a Z3 between 0.8 and 0.9 additional horsepower in drag, but would gain it anywhere from 10 (1.9l) to 30 (euro M) peak HP. The surplus power (actually the torque increase that causes it) will result in improved accelleration up to speeds around 120 MPH.
