Lighter carbon-fiber parts, added muscle everywhere, and a top speed that trips a limiter at 186mph are the highlights of BMW’s upcoming M3 CS Touring xDrive. And it’s something BMW has never done before. Sure, the Bavarian automaker has made a few M3 wagons in its time, but it’s never made a CS range-topping version before.

BMW makes its M3 sport wagon even sharper with the new CS model, which unfortunately won't be sold in America.

BMW is expanding its legendary CS package to the wagon version of the M3, which is not sold in the United States. This high-output wagon uses a 3.0-liter turbocharged I6 to send 543 hp and 479 lb-ft of torque through an eight-speed automatic before hitting the xDrive AWD system.

BMW just keeps pumping out the epic M wagons, and the latest tantalizing model to hit is the M3 CS Touring. Just don’t get your hopes up if you live in America, because like the regular M3 Touring, the CS model won’t be sold in the U.

As per BMW’s other modern CS cars, the 3.0-litre features a new, blowier set of blowers with more charge pressure (2.1 bar), plus a few 0s and 1s inserted into the engine management code to allow for the 20bhp increase. The mountings for this engine are stiffer, too.

The CS treatment for the M3 Touring brings the same 543-hp rating as the hardcore M4 CSL coupe, generated by a tuned version of the twin-turbocharged 3.0-liter inline-6 found in all M3 and M4 models. The performance increase over the 523-hp M3 Competition comes from extra boost pressure and tweaks to the engine’s electronic management.

The limited-production M3 CS Touring has a 3D-printed cylinder head core, higher-boost turbochargers, and a 0-60 time of 3.2 seconds with rollout.

The M3 CS Touring is expected to follow the same formula as the M3 CS sedan that was sold in 2024, which means extra power and less weight.

The ever-confusing BMW M lineup no longer includes an M3 CS in the United States, but the short-lived M3 CS last sold here received an outrageous 543 horsepower from its turbochar
