BMW officially presented the first generation M4 concept on August 16, 2013.[1] However, the concept car did not reveal any interior or technical details. On September 25, BMW released technical specifications of new BMW M4 which will be powered by M tuned S55B30 engine, a derived form of the N55 engine, displacing 3 litre and redlining beyond 7500 rpm. The engine will use two Mitsubishi mono-scroll turbochargers with boost peaking at 18.1 PSI. Power is rated at 430 hp while torque will be over 500 Nm, weight of new M4 will be no more than 1500 kg. Both 6-speed manual and 7-speed M-DCT transmissions will be available.
Carbon fibre reinforced plastic will be used extensively throughout the car, including drive shaft, roof, roof bow, trunk, and front strut brace. For the first time in a M performance vehicle, an electric power steering unit will be used. The steering system will be specifically tuned for the M3 and M4. 18-inch and 19-inch wheel options will be available with lightweight forged alloys being standard. The M compound brakes will be standard (in blue), while carbon ceramic brakes (in gold) will be available as an option.
Although controversial, the M4 will feature Active Sound. A live amplification of the engine's natural sound will be inducted into the passenger cabin via the speakers. There will not be any artificial sound or any pre-recorded track. Overall, 50 percent of the components on the M4 will be standalone compared to the F32 4 Series.[2]
