In BMW-speak, CS means less weight, more power, and fettled chassis and steering settings to create some of the brand's most hardcore cars. So petrolheads will be pleased to know the Bavarian brand has applied this recipe to another car – the M3 saloon, to create the BMW M3 CS.
The CS receives a number of upgrades over the standard car, with a honed version of the chassis fitted to the M3 with Competition Pack. The engine has also been given a slight boost, with around 10 extra horsepower bringing the total to an impressive 454bhp thanks to a more free-flowing exhaust system.
The real story is in the weight-saving department though. While the CS is only available with the heavy seven-speed automatic gearbox, much of the additional weight has been cancelled out by replacing several panels with lightweight carbon fibre. The roof and bonnet are both crafted from carbon-fibre-reinforced plastic, saving 25 per cent over their metal equivalents, while the front and rear bumpers gain carbon splitters and diffusers.
Inside is relatively unchanged, but the starter button has been painted red for a sporty touch. The leather and Alcantara-trimmed innards surround lightweight sports seats for further weight-saving.
These changes mean the M3 CS is faster than even its Competition Pack-equipped sibling, with a 0-60mph sprint of well under four seconds and an electronically limited top speed of 174mph.
Order books for the new M3 CS will open in January. With just 1,200 models available worldwide, UK numbers will be severely restricted to just 100 cars, priced at £86,380 – a hefty £24,800 premium over the standard M3 with Competition Package.
