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.

GregLocock Car companies can only really sell cars that people who are new car buyers will pay a profitable price for. As it turns out fewer and fewer new car buyers want sedans. Large sedans can be nice to drive, certainly, but the number of new car buyers (the only ones that matter in this discussion) are prepared to sacrifice steering and handling for more obvious things like passenger and cargo space, or even some attempt at off roading. We know US new car buyers don't really care about handling because they fell for FWD in large cars.
Slavuta Why is everybody sweating? Like sedans? - go buy one. Better - 2. Let CRV/RAV rust on the dealer lot. I have 3 sedans on the driveway. My neighbor - 2. Neighbors on each of our other side - 8 SUVs.
Theflyersfan With sedans, especially, I wonder how many of those sales are to rental fleets. With the exception of the Civic and Accord, there are still rows of sedans mixed in with the RAV4s at every airport rental lot. I doubt the breakdown in sales is publicly published, so who knows... GM isn't out of the sedan business - Cadillac exists and I can't believe I'm typing this but they are actually decent - and I think they are making a huge mistake, especially if there's an extended oil price hike (cough...Iran...cough) and people want smaller and hybrids. But if one is only tied to the quarterly shareholder reports and not trends and the big picture, bad decisions like this get made.
Wjtinfwb Not proud of what Stellantis is rolling out?
Wjtinfwb Absolutely. But not incredibly high-tech, AWD, mega performance sedans with amazing styling and outrageous price tags. GM needs a new Impala and LeSabre. 6 passenger, comfortable, conservative, dead nuts reliable and inexpensive enough for a family guy making 70k a year or less to be able to afford. Ford should bring back the Fusion, modernized, maybe a bit bigger and give us that Hybrid option again. An updated Taurus, harkening back to the Gen 1 and updated version that easily hold 6, offer a huge trunk, elevated handling and ride and modest power that offers great fuel economy. Like the GM have a version that a working mom can afford. The last decade car makers have focused on building cars that American's want, but eliminated what they need. When a Ford Escape of Chevy Blazer can be optioned up to 50k, you've lost the plot.
