BMW has launched the fifth-generation of the M3 sedan. For the first time, this is a four-door instead of the conventional two. More than 40,000 examples of the fourth-generation BMW M3 Coupe were built, and now the BMW M4 Coupe is poised to continue this success story.
The high-revving six-cylinder in-line engine with M TwinPower Turbo technology newly developed for the new BMW M3 Sedan produces a maximum output of 431 hp. Its peak torque of 550 Newton metres is available across a wide rev band and outstrips the figure recorded by the outgoing BMW M3 by roughly 40 per cent. The improved efficiency, weight savings of around 80 kilograms have been achieved over a comparably equipped predecessor model. 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 engine's power is transferred to the road via a standard six-speed manual gearbox with robust double-plate clutch. This unit is considerably more compact than its predecessor and 12 kilograms lighter. The other option is 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 Smokey Burnout function allows the driver to indulge in a degree of rear wheel spin while the car is moving at low speeds. Stability Clutch Control opens the clutch when the car is understeering to bring it back into line. And M DCT also includes functions like the Drivelogic modes that can be selected by the driver to give the BMW M3 and BMW M4 more comfortable, more economy-focused or even sportier characteristics. The additional seventh gear over the manual gearbox allows longer gear ratios - and delivers the efficiency gains you would expect as a result.
The new BMW M3 Sedan see a return to a six-in-line engine configuration, as used on the second and third generations of this iconic sports car. "When developing a new model we first think about what requirements the vehicle will be expected to meet, then decide which concepts and technologies will best meet these goals," says Albert Biermann. The new engine sees a slight power upgrade over the previous V8 to 431bhp, which is delivered between 5,390 and 7,000 rpm. Peak torque has been increased by roughly 40 per cent to 550 Newton metres, and is maintained over a very wide rev band (1,800-5,390 rpm).
Climbing into the BMW M3, drivers will be greeted by the interior architecture familiar from the BMW 3-Series. The exterior styling also resembles the 3 Series. Of course it has the skirtings and diffusers and other distinguishing factors from the existing 3 Series, not to forget the exhaust noise that makes it audible from far.
