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.

Shortly after several teasers were released, the BMW M3 CS Touring has officially premiered. The German marque has taken off the covers to the new family hauler in Australia on the eve of the Bathurst 12 Hours endurance race before global deliveries begin. Unfortunately, the new model will not be sold in the United States.

BMW M has released teasers on social media of a hardcore performance station wagon wearing M3 CS badging. It's unlikely to come to the U.S.

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.
