On September 25, 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 coming in at 7,300 rpm. The engine uses two mono-scroll turbochargers with a peak boost pressure of 18.1 psi (1.25 bar). The power is rated at 317 kW (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 rpm. The weight of the M4 equipped with a manual transmission is 1,572 kg (3,466 lb) and with the M-DCT, the car is some 40 kg (88 lb) heavier, losing some 80 kg (176 lb) from the E92 M3. Two transmission choices are available, those being the 6-speed manual and 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). With the 6-speed manual transmission, the car accelerates from 0 to 100 km/h (62 mph) in 4.3 seconds.
As per its E92 predecessor, the roof of the coupe model is constructed from carbon fibre (except if the optional sunroof is fitted). Carbon fibre is also used for the bootlid and engine brace. For the first time in a M3/M4 model, an electric power steering unit is used. The steering system is specifically tuned for both the M3 and M4, however it has been criticised for lacking in feel. The 18 inches (460 mm) and 19 inches (480 mm) wheel options are available with lightweight forged alloy wheels being standard. The M compound brakes come standard (with blue brake calipers), while carbon ceramic brakes (with gold brake calipers) are available as an option. maserati wallpapers, bmw wallpaper, ford wallpapers, BMW M4 wallpapers, mercedes wallpapers
(Nissan GT-R)Black Edition
The Black Edition comes with exclusive 20-inch RAYS wheels and a carbon fibre rear spoiler. Recaro racing seats were commissioned specifically by Nissan for the Black Edition. The interior is finished in red and black leather, but a beige colour known as ‘Pale Ivory’ is also available. No mechanical changes are made from the standard GT-R.
