The BMW M4 is a high-performance version of the BMW 4 Series automobile developed by BMW's motorsport division, the BMW M GmbH. Part of the renumbering that splits the 3 Series coupe and convertible models to the 4 Series (to further differentiate it from the 3 Series), the M4 replaced the M3 Coupe and Convertible models. 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.
2-door coupe (F82)
On September 25, 2013, BMW released technical specifications of the M4 powered by a M-tuned S55B30 engine, although it is a 3.0 L inline engine. BMW states that it is completely different to the N55 engine seen in other BMW 35i models, this engine has been built specifically for the New M4/M3, displacing 3.0 L (180 cu in) and redlining at 7,500 rpm. The rev limiter coming in at 7,600rpm. The engine uses two mono-scroll turbochargers with boost peaking at 18.1 PSI. The power is rated at 425 hp (317 kW; 431 PS) while torque will be 550 N·m (410 lb·ft). The weight of the 6 speed manual M4 is 1,572 kg (3,466 lb), with the M-DCT some 40 kg (88 lb) heavier, losing some 80 kg (176 lb) from the E92 BMW M3. 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 (62 mph) in 4.1 seconds). The 6-speed manual transmission does 0 to 100 km/h (62 mph) in 4.3 seconds).
Carbon fiber reinforced plastic is used extensively throughout the car, including drive shaft, roof, roof bow, trunk, and front strut brace. For the first time in the M vehicle, an electric power steering unit is being used. The steering system is specifically tuned for the M3 and M4. The 18 inches (460 mm) and 19 inches (480 mm) wheel options are available with lightweight forged alloys being standard. The M compound brakes come standard (in blue), while carbon ceramic brakes (in gold) are available as an option.
