Following across-the-board updates to the 4 Series and M4 lineup for 2025, BMW’s lineup of track-ready sports sedans and coupes will grow by one for 2025 with the updated M4 CS, which includes these updates along with unique performance equipment designed to… stand out from other BMW M4 models.
For the uninitiated, CS stands for Competition Sport and is the second of three optional performance levels offered by BMW on the M4. It sits between the standard Competition (an upgrade from the standard M4) and the ultra-light CSL. The CS58’s 3.0-liter inline-6 gains 20 horsepower over the M4 Competition, for a total of 543, but produces the same 479 pound-feet of torque. Paired with the standard eight-speed automatic transmission and all-wheel drive, BMW claims a 0-60 time of 3.2 seconds and a top speed of 300 km/h – or a lap of the ring in under 7:22, depending on which of them sail your boat.
The CS gets its own set of lightweight V-spoke wheels and suspension tuning calibrated specifically for this chassis variant. Both carbon-ceramic brakes and R-compound tires are available as upgrades, with the latter free if you’re so inclined. The roof, hood, front splitter, front air intakes, exterior mirror caps, rear diffuser and rear spoiler are made of carbon fiber, which helps keep weight in check.
The exhaust is eight pounds lighter thanks to the titanium muffler. This may sound like BMW scraping the bottom of the barrel looking for ways to save weight, but it’s still not as extreme as the CSL. After all, this one still has a back seat, even if the front ones are made of carbon fiber. Like the center console, shift paddles and various trim elements. All told, the CS weighs about 45 pounds less than the standard Competition, BMW says.
BMW will unveil the 2025 M4 CS to the world on Friday, May 10, in two simultaneous presentations – one at the IMSA WeatherTech SportsCar Championship race at Laguna Seca in California, and the other at the 6 Hours of Spa-Francorchamps World Endurance Car race in Belgium. BMW says customers can place orders from the end of May.
