BMW has now come good with info on its new M3 Sedan and M4 Coupe. We’re entering the fifth generation of this iconic model, but it’s the first in the “M4†era and also the first time the M3 has featured a turbocharged engine, although returning to a straight six configuration.
For the purposes of ease let’s just refer to the two models collectively as the M3, which is now around 80kg lighter than the outgoing V8 model. The standard 6-speed manual gearbox sheds 12kg and includes automatic throttle blipping for downshifts. While the 7-speed DCT, now 40% lighter, features a “Smokey Burnout” feature. No, that’s not a joke:
The Smokey Burnout function allows the driver to indulge in a degree of rear wheel spin while the car is moving at low speeds.
Sending power to the rear wheels is still a key feature of the M3 and BMW has helped control the car’s 317kW by including an Active M Differential. The system ties in with DSC to ensure wheel spin is reduced. In addition, the M Dynamic Mode allows a degree of hooliganism before DSC intervenes to restore order.
The drive for lower fuel consumption sees electromechanical steering make an appearance on the M3 and it features three settings: Comfort, Sport and Sport+. These settings are also complemented with the optional Adaptive M suspension.
BMW says the tailor-made engine provides “smooth and efficient power delivery, very sharp response and reduced fuel consumption and emissions.” Thanks largely to the design of its mono-scroll turbochargers, direct injection and BMW’s well developed Double-VANOS continuously variable camshaft timing.
Weight reduction has been aided by both the Sedan and Coupe having a carbon fibre reinforced plastic roof. A CFRP strut brace in the engine bay not only increases rigidity but also saves 1.5kg compared with the old M3.
Trivia buffs will take note in the fact that production will be split across two facilities. The M4 Coupe will be built at the company’s headquarters in Munich, while the M3 Sedan will be built 120kms to the north at Plant Regensburg.
