BMW’s M4 Coupe range now has a new stablemate with the reveal this week at the Shanghai motor show of the BMW M4 CS.
The M4 CS (Club Sport) is designed to sit neatly in the M4 range between the already meaty M4 Competition Pack and the monstrous M4 GTS - although the latter, also a limited-edition model, is now sold out.
To make it worthy of the CS name, the new special has received a power boost and shed some weight to provide a more ‘sporty’ driving experience, albeit not as manic as the top-end GTS.
Power comes courtesy of the same 3.0-litre twin-turbo inline-six found in the rest of the M4 range, but BMW’s skunkworks tuners have extracted 26kW more over the regular M4 and 7.5kW over the Competition Pack. Torque has been increased by 50Nm, too, bringing it to 600Nm with peak reached between 4000 and 5380rpm.
Coupled to its lighter weight (it’s 32kg and 10kg lighter than the M4 and M4 Competition Pack respectively), the CS can hit the benchmark 0.100km/h in just 3.9 seconds along the way to an electronically limited top speed of 280km/h.
That performance gain, along with a CS-specific suspension tune, helped the M4 CS lap the Nurburgring Nordschleife in 7m38s, a 22-second improvement over the regular M4.
Weight savings come courtesy of liberally used carbon-fibre reinforced plastic (CFRP) including an all-new CS specific front splitter, bonnet, roof, spoiler lip and rear diffuser.
Setting it apart from a regular M4 will be tricky, with only subtle exterior and interior enhancements.
The front splitter is more pronounced than its stablemate while the spoiler lip on the boot is all new. And the grey alloy wheels, 19-inch at front and 20-inch rear, are a new light-weight design specifically for the CS.
Inside, subtle CS badging is enhanced by leather and Alcantara trim wrapping the sports seats. Door trims have been lightened with lightweight fabric door loops as opposed to the more conventional handles.
The BMW M4 CS is expected to receive a limited production run with a BMW Australia spokesperson hinting around 2000-3000 would be produced and made available globally - although a local allocation is still to be specified.
With Australia’s appetite for M cars near insatiable (Australia has the highest rate of M car to regular BMW ownership by percentage anywhere in the world) it’s no surprise the local arm of BMW is keen to get its hands on the M4 CS.
A spokesperson for BMW Australia told CarAdvice today we should see an initial allocation arrive in the third quarter of 2017, although exact timing and numbers - and price - are all still to be confirmed.
