BMW M3 Sedan and M4 Coupe

New engine with torque increased by around 40 percent. The high-revving six-cylinder in-line engine with M Twin Power Turbo technology newly developed for the new BMW M3 Sedan and new BMW M4 Coupe produces a maximum output of 317 kW (431 hp) 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 in 4.1 seconds (with the optional seven-speed M Double Clutch Transmission with Drivelogic).

Systematic lightweight technology.

In the interests of maximizing dynamic ability and ensuring excellent efficiency, weight savings of around 80 kilograms have been achieved over a comparably equipped predecessor model. 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 aluminum for a number of chassis and body components. Indeed, both models feature a carbon roof.

Geared for everyday usability as well as the race track.

One of the primary objectives in the development of the BMW M3 Sedan and BMW M4 Coupe was to ensure the new cars offered impressive race track capability. Hence the presence of a track-specification cooling system, which ensures that the optimum temperature balance for the engine, turbochargers and transmission is maintained at all times.

In order to accentuate the racing character of the two models in terms of both their technical composition and the fine-tuning of the cars, the engineers worked closely with BMW Motorsport’s professional racing drivers during the development phase. For example, DTM drivers Bruno Spengler and Timo Glock took part in the extensive testing and set-up work carried out at the Nürburgring-Nordschleife circuit.
