Better act fast as only 300 cars will be made.

BMW has unveiled the 2018 BMW M3 CS, a limited run variant with more power, a sportier suspension setup, a louder exhaust note, and plenty of carbon fiber-reinforced plastic to make it lighter. The M3 CS follows the M4 CS, which was revealed earlier this year. Production is limited to 1,200 units worldwide with only 550 units coming to the U.S.
