BMW M4 F82 CS: blue color
The 2014 BMW M4 (F82) is a high-performance specification of the first generation BMW 4 Series, which is a successor to the 3 Series Coupé. It replaces the E92 M3 Coupé.
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.
The convertible variant of the M4 was announced along with its coupe sibling, also internally known as F82 or F83 M4. It shares almost everything with the coupé version, but weighs more due to its folding metal roof. The convertible weighs 1,750 kg (3,858 lb) (manual), 1,691 kg (3,728 lb) (M-DCT). The three-piece retractable hardtop folds in 20 seconds. The only significant difference between the two is the weight due to its retractable hardtop. Like its hardtop counterpart, the F83 M4 uses carbon fibre reinforced plastic to lighten and stiffen the car.
