The BMW M4 range has welcomed a new variant in the form of the limited-run special-edition M4 CS. Filling the gap between the M4 Competition Package and track-oriented M4 GTS, the M4 CS is designed for those looking for the sharpest road-focused M4.
Developed at the Nürburgring test track, the M4 CS lapped the circuit in 7 minutes and 38 seconds, just 10 seconds slower than the M4 GTS. It features a fresh round of suspension revisions over the M4 Competition Package, including new spring and damper settings. There’s also a moderate increase in the 3.0-litre in-line six cylinder engine power output, with a hike of 7kW to 343kW accompanied by an extra 50Nm bump in peak torque to 600Nm, enabling a 0 to 100km/h sprint time of 3.9 seconds.
Visually the M4 CS adds a front bumper splitter and boot lid spoiler, both of which made of carbon-fibre. The car’s bonnet and rear diffuser are also now made of the lightweight material, contributing to the M4 CS’ weight of just 1,580kg.
Unlike the M4 GTS, BMW has deliberately steered the M4 CS away from a focus on the track as evident by the fixed, non-adjustable front splitter and the deletion of the GTS’ adjustable GT wing in favour of a rear lip spoiler. In the interests of everyday practicality, the M4 CS also forgoes the roll cage fitted in the M4 GTS.
Inside, the M4 CS boasts Alcantara and leather upholstery and interior trim made from compacted natural fibres – renewable raw materials, in other words – which have been given a special carbon-fibre look. Elsewhere, conventional door pulls give way to lightweight loops, complemented by lightweight M sports seats. It retains comfort features such as a single-zone climate control and a specially adapted version of the HiFi System Professional.
The BMW M4 CS is expected to launch in Australia later this year with local pricing announced closer to launch.
