Priced at $211,610 before on-road costs, the M4 CS is about $80,000 less than the aforementioned GTS but more than $50,000 more expensive than the next model down, the M4 Competition.
For that price buyers will get a more powerful version of the 3.0-litre twin-turbo inline six-cylinder engine used in the rest of the M4 range, with outputs lifted to 338kW and 600Nm - a rise of 7kW and 50Nm compared with the M4 Competition. Power is delivered to the rear wheels via a seven-speed dual clutch automatic transmission.
BMW has also stripped weight from the newest variant, with the 1580kg M4 CS trimming down by 35kg compared to the Competition, although the new variant retains rear seats, unlike the GTS, resulting in an extra 35kg compared to the track-focussed special edition car.
The combination of less weight and extra grunt allows the M4 CS to sprint from 0-100km/h in a claimed 3.9 seconds, while top speed has been limited to 280km/h.
Along with a selection of carbon fibre and carbon fibre reinforced plastic elements throughout the car, including the bonnet which is 25 percent lighter than the standard item, the M4 CS also focusses on aerodynamic improvements, adopting the rear diffuser from the GTS with a small gurney-style spoiler at the trailing edge of the boot lid to enhance downforce.
Standard equipment for the CS includes a head-up display, DAB+ digital radio, an 8.8-inch touchscreen media system with navigation, 12-speaker stereo, single-zone climate control, Alcantara and leather upholstery and interior trim, M steering wheel, sports seats, front and rear parking sensors and auto wipers and headlights.
Buyers can choose from a limited selection of five colours, and a smaller line-up of optional equipment including carbon ceramic brakes, TV and Apple CarPlay, headlight washers, and a rear roller sunshade.
Customer deliveries of the M4 CS are expected to start in Australia from late 2017.
