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.

The BMW revealed the M3 CS Touring, a more powerful and exclusive version of the sports wagon that will not be sold in the United States.

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.

Where that 3.0-liter turbocharged six-cylinder produces 523hp in the not-at-all-regular Competition, it now makes 542hp and 650Nm of torque, allied to an eight-speed dual-clutch transmission and all-wheel drive for rapid acceleration and speed.

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.
