BMW today announced the all-new BMW M3 Sedan and BMW M4 Coupe models, which capitalize on the strengths of the latest 3 Series Sedan and fresh 4 Series Coupe models as their respective foundations. As the first-ever BMW M cars to feature the achievement of an engineered-in reduction in curb weight from one generation to the next, the all-new M3 and M4 stand poised to attack corners, hills, and braking zones, and will vigorously defend BMW M’s decades-strong position as segment leader around the world.
Featuring a return to the inline-6 engine format made famous by BMW M, the all-new, 3.0-liter BMW M3 and M4 engine is approximately 10 kilograms lighter than its V-8 predecessor and packs an even stronger punch. With 425 horsepower from 5,500 – 7,300 rpm, 406 lb-ft of torque from 1,850 – 5,500 rpm, and capable of 0-60mph in 3.9 seconds when equipped with the M-DCT transmission (4.1 seconds with standard 6-speed manual), the all-new BMW M3 Sedan and BMW M4 Coupe will debut at the 2014 North American International Auto Show in Detroit, and will begin sales as 2015 models in early Summer, 2014 (Editor’s notes: All specifications preliminary. Complete US-specific specs, pricing, options, and packages will be announced closer to the on-sale date).
The launch of the new BMW M3 Sedan and new BMW M4 Coupe sees BMW M GmbH revealing a new interpretation of the high-performance sports car – and carrying the BMW M philosophy over into the fifth generation of the M3. 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 “M4” badge is a reference to the model series that provides the basis for the new M model – and, for the first time, the Coupe will be introduced at the same time as the four-door variant. Logic dictates the latter will be christened the BMW M3 Sedan.
“Four generations of the BMW M3 have blended motor sport genes and uncompromised everyday usability within an emotionally rich overall concept,” explains Dr Friedrich Nitschke, President BMW M GmbH. “The BMW M3 Sedan and BMW M4 Coupe represent an ongoing commitment to this philosophy. The engine is the heart of every M model, and the new turbocharged six-cylinder unit fitted in the two new cars combines the virtues of a high-revving naturally aspirated unit with the strengths of turbocharger technology. A committed lightweight design concept produces a weight saving of around 80 kilograms over the outgoing M3. The BMW M3 and BMW M4 take motor sport technology from the track to the road, and thousands of laps of the legendary Nürburgring Nordschleife – the world’s most exacting race track – have readied the new models for that transition. Meticulous and passion-fuelled development work has underpinned the creation of two high-performance sports cars that set new standards in terms of overall concept, precision and agility.”
The high-revving, inline-6 engine with M TwinPower Turbo technology freshly developed for the new BMW M3 Sedan and new BMW M4 Coupe produces a maximum output of 425 hp. Its peak torque of406 lb-ft is available across a wide rev band and outstrips the figure recorded by the outgoing BMW M3 by roughly 40 percent. And yet the engine also achieves a reduction in fuel consumption and emissions of nearly 25 percent. Both the BMW M3 Sedan and BMW M4 Coupe cover the sprint from 0 to 60 mph in 4.1 seconds with the standard 6-speed manual transmission and even 3.9 seconds with the optional 7-speed M Double Clutch Transmission.
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 curb 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-fiber-reinforced plastic (CFRP) and aluminum for a number of chassis and body components. Indeed, both models feature a carbon roof.
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.
Low-slung and broad-set, the new BMW M3 Sedan and new BMW M4 Coupe share a finely balanced stance on the road. Indeed, the M-specific design of the two high-performance sports cars underlines their performance capability. Large air intakes and Air Curtains at the front end, exposed carbon-fiber-reinforced plastic (CFRP) and aluminum body components, and the diffuser at the muscular rear end are not merely design flourishes; they also fulfill functional roles in terms of aerodynamics, cooling and weight saving.
