BMW’s current generation M3 and M4 are angry, violent machines capable of terrifying fast turns. It seems unlikely that anyone who’s had the chance to drive hard in an M3 Competition would ask for an even more hardcore version, but that doesn’t stop BMW from giving us one. Enter the 2024 BMW M3 CS, which debuted on Tuesday and promises a lighter, stronger and faster four-door M car.

Other than that, the current M3 is a great car. It largely fixes all the issues I had with the previous version. Much of that comes down to the addition of available all-wheel drive and a conventional automatic transmission instead of a dual-clutch auto. I know, both sound like downgrades, things that would dilute the driving experience, but they actually make the car much faster on real roads, not to mention more fun to live with overall. That’s why the CS is rad, because it uses the M3 Competition xDrive as a base and then cranks the wick up.

As part of its plan to ramp up the intensity of an already intense car, BMW has gone gorillas on the 3.0-litre turbocharged inline six-cylinder, increasing boost to a borderline of rude 30.5 psi to take a 40 horsepower punch over the M3 competition, for a total of 543 ponies. Peak torque of 479 lb-ft comes in at 2,750 rpm and lasts to 5,950 rpm. The people of Munich claim that this is enough to push the M3 CS to 100 km/h in just 3.2 seconds and an electronically limited top speed of 300 km/h.

Adding power is one thing, but losing weight is the best way to improve a car’s performance. To this end, BMW has fully embraced carbon fiber reinforced plastic (CFRP) and used it in the roof, bonnet, front splitter, front air intakes, wing mirror caps, rear diffuser and rear spoiler of the CS. The interior also uses it in the center console, paddle shifters and some trim pieces. The very uncomfortable M Carbon bucket seats are now standard equipment, as is a titanium rear muffler, which BMW says saves about eight pounds. BMW says the CS is about 75 pounds lighter overall than the regular M3 Competition xDrive.

The rest of the car is pretty much standard M3 Competition, which is to say quite nice, and while the list of standard go-fast parts is longer, things like carbon ceramic brakes and Michelin Sport Cup 2 tires are optional extras. That might seem reasonable, except the CS adds a whopping $37,095 to the price of the M3 Comp xDrive it’s based on – or about one GR Corolla, pre-dealer markup – for a total of $119,695, includes a $995 destination fee.
