2025 BMW M4 CS Sheds Weight and Increases Power to Dominate Track Days

BMW sharpens the M4’s track manners with the 2025 BMW M4 CS. The latest addition to the CS family uses race proven formula of weight savings and increased power to help achieve perfect lap times.

The quest for the perfect lap time is an enduring challenge in the minds of many performance drivers. Mastering the track and its apexes is one part of the puzzle, but a piece that many often overlook is what their car is bringing to the race. 

BMW is hoping that the 2025 BMW M4 CS can help them enter the winner’s circle thanks to its combination of weight savings, performance upgrades, and exterior styling that’s sure to draw plenty of stares. 

 

M4 CS styling is razor focused, will come in two colors

The exterior styling of the CS builds on the core fundamentals of the base M4 and turns the volume up a notch with a number of weight-saving features. The large front twin-kidney grille on the CS is frameless and is lighter than the standard grille with the piece getting red contour lines and CS badging in the upper portion of the horizontal bars. The headlights illuminate in yellow instead of white when buyers walk up to the car, with the color also appearing when the low beams are on. BMW says that this is a nod to their GT race cars. 

The rest of the car also gets plenty of carbon fiber with the hood, front splitter, exterior mirror caps, front air intakes, roof, rear spoiler, and the rear apron all being made out of the material. The channels that run along the hood also get slathered in carbon fiber. BMW is also limiting the color choices on the M4 CS at launch with the model only being initially offered in two colors: Riviera Blue, and Frozen Isle of Man Green Metallic. 

M4 CS interior is blend of race-ready function and elegant luxury 

The interior of the CS also builds on the M4 source material with the model getting a 3-spoke Alcantara covered M flat-bottomed steering wheel with the top of the wheel getting a prominent center line while the shift paddles have been replaced with ones made out of CFRP. 

The model also gets M Carbon Sport Bucket seats upholstered in Merion leather with the seats getting a red and black bicolor scheme. The CS also gets BMW’s Curved Display system with the 12.3-inch digital instrument cluster and the 14.9-inch infotainment system being housed under one large pane of glass.

More power and less weight makes a difference at the track 

The M4 CS may seem like a wild attempt to put the M4 on a crash diet, but look past that and you’ll see that BMW engineers also beefed up the engine too with the CS’s 3.0-liter twin-turbo inline-six producing 543 hp. 

That’s 20 more than what you get in the standard M4 Competition and it didn’t require BMW to make too many alterations either with the increase being solely due to engineers raising the boost pressure of the two turbochargers to 32 psi and modifying the engine management parameters. 

The enhanced power allows the CS to make the sprint to 60 mph in 3.2 seconds before topping out at 188 mph. An eight-speed automatic is standard, and the CS also gets the M xDrive system to help keep the engine’s power firmly planted on the pavement. Buyers looking for a 2WD experience can alter the settings to bring all the power to the rear wheels. The suspension also has tuning specific to the CS model with the adaptive dampers embracing a CS-exclusive setup to help tighten up high-speed cornering behavior. The CS also gets upgraded brakes to help provide stable stops when preparing to enter a tight corner or switchback. 

Pricing for the 2025 BMW M4 CS starts at $123,500 with the model slotting above the $88,300 Competition model. Production will begin in July with sales following shortly after.
