The BMW Z4 M Coupe loses some fun compared to the roadster since it can't lose its top on a beautiful day but it makes up for it with better structural rigidity and therefore better performance.  This is proven on the Nordschleife, the Northern Circuit of Nurburgring, where the Z4 M Coupe outperforms the lap times of even the BMW M3 and the BMW Z4 M Roadster. Powered by the same prize-winning 3.2-litre straight-six M engine also featured in the BMW M3 and the BMW Z4 Roadster. the performance figures are indeed impressive at very first sight: 3,246 cc displacement, 333 bhp maximum output at an engine speed of 7,900 rpm, maximum engine speed of 8,000 rpm. And no less than 80 per cent of maximum torque of 262 lb-ft is available from just 2,000 rpm.

Output per liter is 103 bhp, giving the Z4 M Coupe a power-to-weight ratio of just 9.9 lb/bhp. Acceleration to 60 mph comes in 4.8 seconds and top speed is limited electronically to 155 mph.  The superior engine and drivetrain of the BMW Z4 M Coupe are matched by an equally superior high-performance suspension. In its basic concept, the suspension is identical to that of the BMW Z4 M Roadster, but has nevertheless been geared specifically to the particular requirements of the fixed-head model.
