Powering the M3 CS from 0-62 in 3.9 seconds - and on to a top speed of 174mph - is a 460hp turbo-charged straight-six, putting out 443lb ft of torque. That's 10hp and 37lb ft more than the Competition Package for those of you playing at home. While underneath you'll find a "motorsport influenced" Active-M suspension set-up - complete with double-wishbones at the rear and a Competition Package setting for the springs and dampers - and a specially tuned M Sport exhaust system.
Following the motorsport theme, the M3 CS comes equipped with a weight-optimised magnesium oil pan which, "keeps the surge of the lubricant even" at forces of up to 1.5g - make your own jokes here - and an individual oil cooler, allowing the seven-speed dual-clutch gearbox to withstand "even the hardest driving conditions".
Inside you'll find a smattering of Alcantara and the lightweight seats from the Competition Package. But, despite its reductionist nature, the M3 CS still boasts amenities such as climate control and a Harman Kardon Surround Sound System.
Production is limited to just 1,200 units in the UK, which will be available to order from January 2018 onwards, with the first cars due to be built in March. With its flared arches and purposeful stance, the Club Sport additions ought to make the fast foor-door even more of a looker, we'll have to wait to find out whether it'll have the substance to match the style, and the price tag.
