Like the M4, the M3 is expected to use a twin-turbo 3.0-liter six-cylinder engine that develops approximately 420 bhp (313 kW). It will likely be connected to a six-speed manual or a seven-speed M DCT Drivelogic gearbox.
The 2014 BMW M3 could be introduced alongside the M4 Coupe at the North American International Auto Show but nothing is official as of yet.
