BMW M4 white colour
The BMW M4 is a high-performance version of the BMW 4 Series coupes and convertibles developed by BMW’s motorsport division, BMW M, and marketed since 2014.
As part of the renumbering that splits the 3 Series coupé and convertible models into the 4 Series, the M4 replaced the BMW M3 coupé and convertible models. Upgrades over the standard BMW 4 Series include an upgraded engine, suspension, exhaust system, brakes and weight reduction measures including increased use of carbon fibre, such as on the roof of the car.
First generation (F82/F83; 2014)
On 25 September 2013, BMW released the technical specifications of the M4. It is powered by the S55B30 engine, which is developed and engineered by BMW M GmbH.
This 3.0-litre inline-6 engine has been built specifically for the new M4/M3, having a redline of 7,600 rpm with the rev limiter actuated at 7,300 rpm. The engine uses two mono-scroll turbochargers with a peak boost pressure of 18.1 psi (1.2 bar).
The power is rated at 317 kW (431 PS; 425 hp), however this is achieved not at a specific engine speed, but is instead rated throughout the range of 5,500–7,300 rpm.
The engine’s torque is rated at 550 N⋅m (406 lbf⋅ft) throughout the range of 1,850–5,500. Two transmission choices are available, the 6-speed manual and the 7-speed M-DCT transmissions.
The 7-speed M-DCT transmission accelerates the car from 0 to 100 km/h (62 mph) in 4.1 seconds) and the 6-speed manual transmission from 0 to 100 km/h (62 mph) in 4.3 seconds.
The weight of the European specification M4 equipped with a manual transmission is 1,572 kg (3,466 lb) and with the M-DCT dual-clutch transmission, the car is some 40 kg (88 lb) heavier, losing some 80 kg (176 lb) as compared to the E92 M3.
