The car maker describes the model as a ‘more civilised’ version of its 493bhp M4 range-topper. The CS will still be able to handle track work, and production will be limted to just 60 examples.
Figures are yet to be released, but the CS’s positioning as a halfway-house between the regular M4 and the full-blown GTS suggest that its twin-turbocharged 3.0-litre straight-six engine could produce something in the region of 450bhp.
The CS will use BMW’s familiar seven-speed dual-clutch automatic gearbox and gets carbon-ceramic brakes, a rear wing and carbonfibre body trim. To make it more versatile than the GTS, it ditches a half roll cage in favour of a pair of rear seats.
The chassis comes with BMW’s adaptive M system as standard and the car rides on 20inch wheels, which appear to have a near identical design to those on the GTS.
