As a power plant in a convertible, a V-shaped eight-cylinder naturally aspirated gasoline engine with a volume of 4 liters is used. The engine is high-speed, so its maximum power is 420 hp. reached at 8,300 rpm, and peak torque of 400 Nm at 3,900 rpm.
Due to the use of a comfortable rigid automatic folding roof, the convertible loses a little in acceleration to the platform coupe BMW M3 - 5.3 vs. 4.8 seconds. Top speed is electronically limited to 250 km/h.
The base transmission is a six-speed “mechanics”, but as an option for the convertible, a seven-band M DCT Drivelogic robotic transmission with 11 different shift modes is also available.
Serial production of the BMW M3 Convertible has been launched at the company's plant in Germany.
