The move to eight cylinders in the fourth generation BMW M3 provides a powerplant offering the seemingly disparate characteristics of more power, increased efficiency and reduced weight when compared with the previous six-cylinder M3 engine. Displacing 3,999 cubic centimeters (4.0 liters), the new light-alloy engine produces 414 hp at 8,300 rpm and 295 pounds-feet of torque at 3,900 rpm with 85 percent of the maximum torque available consistently through 6,500 rpm. This power output represents a 24 percent increase over the six-cylinder from the last generation M3 and it comes with a seven percent weight saving. Compression ratio is dialed in to 12.0:1 and redline is set at 8,400 rpm.

Also in addition to the traditional 6-speed manual transmission, the new M3 convertible premieres a new 7-speed double clutch transmission specially designed for a high-rpm engine. The M double-clutch transmission with Drivelogic (M DCT Drivelogic) shifts gears without the slightest interruption in the flow of power. As a result, M DCT Drivelogic is able to extract the most performance possible from the car while also providing a smooth comfortable shift from one gear to the next.
