BMW has gotten plenty of mileage from its inline-six engines, but it’s not done yet. The 2025 M4 CS will debut on May 10, sporting a 543-horsepower turbocharged engine, plenty of carbon fiber-reinforced plastics, and chassis reinforcements to give it razor-sharp handling.

The $124,675 coupe uses BMW’s S58 inline-six-cylinder engine, which also powers the M4 GT3 race car that won the DTM title in 2022. It uses a 3D-printed cylinder head core that improves cooling, and the oil system has been revised to maintain lubrication during high revs and aggressive cornering. The engine has 20 more horsepower than the M4 Competition Coupe, which BMW said is due to it cranking the turbos up to 30.5 psi. It also makes 479 pound-feet of torque and sports a 7,200 rpm redline. That power hits all four wheels through an eight-speed automatic transmission, an active M differential, and BMW’s xDrive AWD system.

An M4 CS-specific adaptive M suspension system provides adjustable damping settings, and forged alloy wheels reduce unsprung weight. Track tires or ultra-track tires are available as no-cost options.

BMW employed carbon fiber-reinforced plastic and full carbon fiber to cut the car’s weight. It features a carbon roof, while the hood, front air intakes, mirror caps, rear diffuser, and rear spoiler are made from the carbon-plastic composite. Even the exhaust is lighter, cutting eight pounds from the car with a titanium muffler, and BMW said the M4 CS is 77 pounds lighter overall than the M4 Comp.

Interior features include an Alcantara-wrapped steering wheel and the automaker’s annoyingly ass-crunching M Carbon Bucket Seats. The fact that they’re upholstered in Merino leather is nice, but most of us are too wide to fit into them without significant discomfort. BMW’s iDrive 8.5 infotainment software runs on a 12.3-inch digital gauge cluster and 14.9-inch touchscreen, and the car gets unique widgets to monitor and manage its performance.

keep the color. lose the stupid front design. make it reliable, at least as reliable as a base 911. Then and only then is it somewhat worthy of that price.

I’m not an engineer but 30psi seems really high for factory turbo.

Mustangbear I was a young engineer at Ford in 1991, feeling very privileged to work on a team located inside the proving grounds. I remember seeing a group of people clustered against the windows at the side of the building abutting the high-speed track. As I joined them, I saw they were watching two very sleek coupes take a couple laps. Minutes later, the cars were in our parking lot, and everyone rushed outside to take our first look at the undisguised 1993 Mark VIII.
El scotto Posky owes you lunch, you got more comments.
El scotto My new beret would be the cheapest thing involved with restoring this. Well, maybe a pack of French cigarettes.
El scotto No, no, and once again NO! Here in the metro D.C. Kia dealers are advertising Tellurides with cash on the hood. Here's what makes people laugh out loud: "1.9% financing for well-qualified buyers"! So maybe, and I'm being very, very, very generous here; maybe .01 of 1% of Kia buyers can at least fill out the paperwork to be considered well-qualified. They are all low curdogs, Kia North America, their dealers, and those willing to pay extra for something that depreciates.
Bd2 So sad, "Anal" is in here posting as himself and then calling himself out after the fact while pretending to be me. The Telluride has it's share of minor issues but is the best SUV from a "non-premium" brand even with higher MSRPs, the sales keep on rising even in the 6th year of production. The next generation will bring greater size, turbo engines, 2 hybrid variants, further improvements to the premium feel, and a definitive infotainment and safety suite.
