The 2014 BMW M4 makes its world debut today. The first BMW M4 Coupe will launch in Summer of 2014.
The high-revving six-cylinder in-line engine with M TwinPower Turbo technology newly developed for the new BMW M3 Sedan and new BMW M4 Coupe produces a maximum output of 431 hp. Its peak torque of 550 Newton metres (406 lb-ft) is available across a wide rev band and outstrips the figure recorded by the outgoing BMW M3 by roughly 40 per cent. And yet the engine also achieves a reduction in fuel consumption and emissions of around 25 per cent. Both the BMW M3 Sedan and BMW M4 Coupe cover the sprint from 0 to 100 km/h / 62 mph in 4.1 seconds (with the optional seven-speed M Double Clutch Transmission).
The BMW M4 Coupe, for example, has a DIN kerb weight of 1,497 kilograms, thanks to the rigorous application of intelligent lightweight design measures. These include the increased use of lightweight materials such as carbon-fibre-reinforced plastic (CFRP) and aluminium for a number of chassis and body components. Indeed, both models feature a carbon roof.
The third generation of the M DCT sees the M engineers once again setting the benchmark in terms of power and race track capability without having to compromise on everyday usability. The optional seven-speed M Double Clutch Transmission with Drivelogic prompts the new high-revving turbocharged engine into emotionally impressive feats.
Among the other components that add fresh polish to the dynamic repertoire of the BMW M3 Sedan and BMW M4 Coupe are the hollow lightweight output shafts of the rear differential and the Active M Differential, which uses an electronically controlled multi-plate limited-slip differential to optimise traction and directional stability.
On the BMW M4 Coupe, the contoured roofline with central channel continues into the boot lid, emphasising the even sportier personality of the new model. The newly developed boot lid not only provides extremely effective tail end styling, its geometry is at the same time precisely tailored for optimised aerodynamics, while the use of carbon fibre and plastics makes for additional weight savings.
The BMW M4 Coupe features an integrated rear spoiler and is made from particularly lightweight carbon-fibre-reinforced plastic. As well as performing a functional aerodynamic role, the tailgate also contributes significantly to the BMW M4’s standalone design. Indeed, the pair of lines which begin life flanking the power dome in the bonnet – and score a clearly defined path over the CFRP roof – complete their journey in the boot lid.
