This is BMW’s all-new M4 CS, a model designed to sit above the standard M4 and M4 Competition, and below the 2022 limited-edition CSL. The Bavarian carmaker wants to underscore the connection between the M4 CS and an intense, ’emotional’ driving experience, describing the CS as possessing a distinctive character. However, setting character aside, the CS sounds very familiar in many areas. Like the CSL, it features the same 543 hp powerplant found in the M3 CS. It also incorporates all-wheel drive—unlike the rear-wheel drive CSL—and prioritizes weight reduction. Its appearance even mirrors that of the CSL.
Just as they did with the CSL, BMW talks a
lot about weight savings and track focus with the M4 CS — but if the CSL became
anorexic, the CS has chosen to go on something a little more sustainable, like
cutting out those pesky carbs. The 2025 BMW M4 CS features a carbon roof, hood,
front splitter, front air intakes, exterior mirror caps, rear diffuser, and
spoiler. It also has light-alloy forged M alloy wheels, which can be equipped
with track tires or “ultra-track” tires, both as a no-cost option. However,
compared to the CSL, you miss out on the non-adjustable-backrest carbon bucket
seats and carbon fiber trunk lid. With the CS, you also get to keep the rear
seats and sound insulation. You do get the M Carbon bucket seats that could be
spec’d by CSL owners not interested in inflating the bottom line of their
chiropractor. The result is that the BMW M4 CS shaves 20 kg compared
to the M4 Competition Coupe with xDrive, whereas the M4 CSL’s crash diet lost
it a whopping 108 kg. The BMW M4 CS also gets a modest power bump,
with it sharing the same engine output of the M3 CS. And yes, that’s the same
as the M4 CSL if anyone is keeping score.
Under the hood is the S58 3.0-liter
straight-six turbocharged engine with 543 hp and 649 Nm. That’s an increase of 20 hp over the 2025 BMW M4
Competition Coupe. Granted, that bump in power isn’t as impressive as it would
have been a year ago, given the recent 2025 M4’s facelift, which brought with
it another 20 hp (20 PS / 15 kW). Essentially, the engine is the same as that
found in the standard M4. However, the CS’s motor gets more boost and the
associated tuning, resulting in increased power. On the road, that translates
to a 0–100 km/h time of 3.4 seconds and an electronically limited
top speed of 302 km/h. You get an active exhaust, too, with the note
changing according to which drive mode you select. Want to wake the dead, and
you can select either Sport or Sport+ modes to open up the flaps, letting the
dual-branch exhaust system and titanium rear silencer really sing. While this
is an xDrive — BMW-speak for all-wheel drive — the Bavarian company, famed for
its rear-drive chassis, goes to great lengths to emphasize how this is still a
rear-biased setup. As with other xDrive M cars, you can choose to decouple the
front drive wheels altogether for some drifty antics, although you’ll probably
get the fastest times out of M4 CS by taking advantage of the electronic
all-wheel drive control that sends power to the wheels that need it most.
No manual options here. You get a button
on the gear selector that lets you choose from one of three different shift
characteristics — presumably ranging from comfort to bucking bronco. Speaking
of stiff shifts, there are also “unique engine mounts” that have been stiffened
to provide a “rigid connection between the engine and the vehicle’s structure”
— that sounds like a way of introducing more NVH into the cabin, but we guess
it will have the effect of increasing the connection to the machine too. It
probably feels better with the M4 CS’s exclusive chassis tuning. On the
electronic wizardry side of things, the Adaptive M suspension has a setup
specific to the M4 CS, as do the electromechanical M Servotronic steering with
variable ratio and the integrated braking system. Those good-old physical
parameters have been tweaked, too, with CS-specific wheel camber settings,
dampers, auxiliary springs, and anti-roll bars.
It’s hard to stop drawing similarities
between the new M4 CS and the limited-to-1000 BMW CSL, but they keep presenting
themselves, particularly when you look at one of the more divisive elements of
the car’s design: the grille. Yep, while we already knew the nostril-like
design was here to stay, BMW seems to have carried over the most distinctive
part of the CSL to the CS — the weight-saving grille. It’s lighter because it
features fewer elements, of course. There is one change — there’s an M4 CS
badge on the left snout. Still, we’d wager that a few people who plumped to get
the uber-exclusive CSL will be a little miffed that the CS looks this similar —
even an expert would be seen squinting to tell the external differences between
the two at this point. The M4 CS will be available in four colors. From the
standard palette, you get either Brooklyn Grey metallic or Black Sapphire
metallic, and from the BMW Individual selection, you can opt for Riviera Blue
or Frozen Isle of Man Green metallic.
Meanwhile, within the hood, you get
channels showcasing some exposed carbon goodness. Also left unpainted are many
of the CFRP bits, including the roof. Combined with black side skirts, gills,
and exhaust tips, you effectively get a contrasting two-tone-ish exterior.
Wheels can also be had in matte black or, if you want to change things up,
matte Gold Bronze. Meanwhile, the headlight elements, formerly known as the
company’s iconic halos (and are now some kind of upside-down-L-shaped boomerang
things), light up in yellow as a tribute to the GT race cars. At the rear, the
same trippy LED laser diode lights make their return.
The interior sticks with BMW’s curved
display setup, with a 12.3-inch digital instrument cluster and a 14.9-inch
infotainment screen positioned in the center of the dashboard. Like the rest of
the range that was updated for 2025 MY, the M4 CS runs BMW iDrive 8.5, but with
M-specific graphics. Also of note is that iDrive 8.5 cuts down on the number of
physical buttons in the cockpit, integrating more functionality into the
touchscreens. There are also the gimmicky but fun additions of a drift analyzer
and lap timer. At the same time, the M buttons on the steering wheel can store
individual setups, including gearbox settings, DSC, and — perhaps the most
useful in a day-to-day capacity — whether you want automatic start/stop to be
active. Elsewhere in the interior, you’ll find plenty of “CS” lettering, as
well as seat belts with M-tricolor stitching, interior trim strips in Carbon
Fiber, and an Anthracite-colored headliner. Those aforementioned M Carbon
bucket seats are finished in Merino leather in a Black/Red color scheme with
distinctive contrast stitching. They get full power adjustability, seat
heating, and illuminated M4 CS logos in the headrests.
The 2025 M4 CS will go into production at
BMW’s Dingolfing plant in July 2024, while it will make its world debut on
Friday the 10th of May at both the IMSA WeatherTech SportsCar Championship race
at Laguna Seca, US, and in Europe at the 6 Hours of Spa-Francorchamps World
Endurance Car race.
Order books will open at the end of May. The base MSRP is US$ 123,500 plus US$ 1,175 for destination and handling. To put that into perspective, the 2025MY of the BMW M4 starts at US$ 79,100 for the base coupe, not including a US$ 995 destination fee. A more apt comparison, however, would be with the similarly equipped all-wheel drive 2025 BMW M4 Competition xDrive Coupe, which costs US$ 88,300 (plus a US$ 995 destination fee). Altogether, that represents a significant premium for the CS, positioning it not far from the 2022 M4 CSL’s price tag of US$ 139,900.
