Images of the 2015 BMW M3 and M4 models were released online a day prior to the official BMW unveiling. To our delight, technical specs were also divulged.
Both the M3 and M4 will have turbocharged 3.0-litre inline six-cylinder engines and make 425 horsepower (up from the previous generation’s 414 horsepower) and 406 lb-ft of torque. 0-100km/h time will be 3.9 seconds for the DCT transmission and 4.1 seconds for the purists who prefer manual.

Fuel consumption has also improved by 25% compared to the previous model. We can likely credit that to the more efficient turbocharged engine (vs the old V8) and the approximately 175 lb (80kg) weight savings.
Other interesting features include a “smokey burnout function”, M logos in the seatbacks that illuminate and 50% unique parts compared to the non-M models.
Production is set to begin in early summer 2014. The M3 will be produced in the Regensburg plant (built alongside 3 Series Sedan) and the M4 will be produced in Munich plant (built alongside 4 Series Coupe).
Here is the press release:
The new BMW M3 Sedan and new BMW M4 Coupe:
Innovative engine technology and a focus on lightweight design.
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 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 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).
In the interests of maximising 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 igorous 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.
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.
