Buoyed by a sales surge that saw 80,000 M cars find homes in 2017, BMW is working hard to increase its performance division’s portfolio, and this is the latest to hit showrooms. Limited to just 1,200 units worldwide, BMW says it’s already nearly sold out - so if you want one, you’ll need to be quick.
In an attempt to shave those all-important kilos, BMW fitted new forged alloy wheels and replaced heavy panels, such as the roof and bonnet, with carbon-fibre-reinforced plastic.
The front seats have been thrown out in favour of new weight-saving replacements, while even the centre console has been stripped back and lightened. BMW fans might be wondering why the CS is missing an ‘L’ in its name - made famous most recently by the E46 M3 CSL.
Well, according to BMW’s M boss, although the diet for the CS was extensive, it wasn’t quite enough to justify the ‘Lightweight’ tag that comes with a CSL nameplate. But don’t let that put you off - this is still one very special machine indeed.
BMW has worked its magic under the bonnet to produce even more horsepower from the already-impressive 3.0-litre, twin turbo unit. Power is up 10hp to 460hp while torque increases 9%t over the 550Nm in an M3 Competition Package to 600Nm.
That extra oomph and trim waistline means the CS will hit 100km/h in just 3.9 seconds - enough to furrow the brows of many supercar owners.
Engineers have even ditched the speed limiter, so German autobahns can be navigated at speeds of up to 280km/h.
And believe us, thanks to a Munich-based test drive, we can confirm the Germans weren’t joking. Cautious drivers can expect to see around 8.3l/100km, although it’s unlikely many CS buyers will be cautious types. In reality, you’ll be languishing in the teens if you use it as its creators intended.
On road or track, the CS is astonishing. Revving to a heady 7,600rpm, the engine is awash with power, accompanied by a noise that sends shivers down your spine like a first love. The Michelin Pilot Sport Cup 2 tyres are super-sticky, and on a hot, dry track - like that which we were blessed to lay black lines across in Germany - serve only to compose the BMW like a ballerina, balanced perfectly on its toes.
The way the CS sheds speed, thanks to huge carbon ceramic brakes, is a close match for a direct impact with a tree, while the seven-speed DCT automatic gearbox is a delight, rocketing through gears faster than ever. In some driver settings (of which there are many), the steering does lack feel but it’s not awful, and we’d like the seats to be a little more comfortable and easier to adjust.
A pretty carbon-fibre spoiler, wailing quad exhaust pipes, speed-bump-kissing front splitter and distinctive matt purple paintwork (one of five unique colours) help the CS stand out from the fast-lane-inhabiting 3 Series crowd. Low-slung and aggressive, it’s lost none of the M3’s imposing road presence.
Inside, an optional BMW M Performance Alcantara steering wheel with 12 o’clock marker is a must-buy. It’s simply wonderful to hold and adds to the CS’s drama. The usual BMW smattering of technology can be found too - including the much-improved new iDrive system with connected information services, such as traffic and weather updates, and an impressive Harman Kardon stereo.
Adaptive LED headlights, electrically folding mirrors, navigation and parking assistance all come as standard, with the rear-view camera relegated to the options list. Why? It saves weight...
BMW’s M division really is on a winning streak, and the CS proves it. Just weeks after unleashing the new M5 we get another hit with this - a future classic in the making. With a raucous turn of speed, soundtrack to worry a hip-hop chart-topper, and driving experience that few cars could even come close to delivering, the M3 CS is surely set to become yet another Munich legend.
