BMW has released a new promo featuring the M4 Coupe and M3 Saloon which focuses on their competency on a circuit.
Under the hood lies the new twin-turbocharged 3.0-litre S55B30 in-line six-cylinder fed by two low internia turbocharger units. Mated to a 6-speed manual or optional 7-speed M-DCT transmission, 316 kW (430 hp) and 550 Nm of torque is sent to the rear wheels via a lightweight carbon fibre reinforced prop shaft and revised M differential utilizing an electric actuator to constantly vary the locking effect – anywhere between 0 per cent and 100 per cent.
Both vehicles can crack 100 km/h in 4.1 seconds, while maximum speed is electronically restricted to 250 km/h (155 mph); if the optional Driver’s Package is specified, this limit is raised to 280 km/h (174 mph).
