What is it?
The BMW M5 Competition Package is the fastest M5 yet and, along with similarly specified versions of the M6, the most powerful road car BMW has ever built.
It sees the standard car fitted with a range of performance-enhancing parts and a new engine calibration that boosts the power figure by 15bhp to 567bhp. While peak torque remains unchanged, it is available over a slightly wider range of engine speeds.
Resultantly, the 0-62mph time is reduced by 0.1sec to 4.2sec and the 0-124mph time is shaved by 0.2sec. Top speed remains limited to 155mph.
The bigger changes concern the chassis. The springs and damping rate has been increased by 20 per cent, and the anti-roll bars are 15 per cent stiffer. The car sits 10mm lower. The Active M Differential has a standalone control unit, the ESP’s M Dynamic mode allows a greater angle of slip and the steering has a new map to make it 10 per cent more direct than the standard car. An active flap in the exhaust increases noise at high speeds.
