BMW has created a sporty new variant of their M4 Coupe. The limited-edition M4 CS. With an increase of 10 horsepower over the standard M4, the CS inline turbocharged 6-cylinder snaps from 0-60 in 3.9 seconds with a top speed of 174 MPH. It features Adaptive M suspension, Alcantara seats & door panels, and to shave pounds, a lightweight roof made of carbon-fiber reinforced plastic.
