The BMW M4 is a high-performance version of the BMW 4 Series automobile developed by BMW's motorsport division, the BMW M GmbH. Upgrades over the standard BMW 4-Series include: a very powerful and responsive, twin turbocharged engine; improved handling, suspension, and braking systems; aerodynamic body enhancements; interior/exterior accents with the tri-colour "M" (Motorsport) badging; the significantly reduced weight compared to the standard 4 series and its predecessor with an all-new stiffer chassis and extensive use of carbon fiber, especially the roof of the car.

The engine uses two mono-scroll turbochargers with boost peaking at 18.1 PSI. The power is rated at 425 hp while torque will be 550 N·m. The weight of the 6 speed manual M4 is 1,572 kg. Both 6-speed manual and 7-speed M-DCT transmissions are available. The 7-speed M-DCT transmission accelerates the car from 0 to 100 km/h in 4.1 seconds. The 6-speed manual transmission does 0 to 100 km/h in 4.3 seconds.
