The anticipation is over as BMW unveiled the new M3 and all-new M4 coupe, powered by an all-new 3.0L straight-6 cylinder that is approximately 10 lbs. lighter than its V8 predecessor.

Despite the loss of two cylinders and a reduction in size, power on the new M sedan and coupe has been upgraded to 425 horsepower from 5,500 to 7,300 rpm, and 406 lb-ft of torque is available from 1,850 to 5,500 rpm for incredible throttle response at any speed.

Being launched alongside the all-new 2 Series at the North American International Auto Show in January, the M3/M4 showcases a new level in performance aerodynamics for an incredibly efficient design. Starting with the front fascia, air curtains in the front apron channel air through the bumper and around the wheels to reduce drag; exposed carbon fibre-reinforced plastics (CFRP) reduce weight and give an added style element, and the rear bumper features integrated sills that are equal parts style and function.

“The way in which we channel the inflowing air through the engine oil cooler creates a Venturi effect, which reduces front axle lift and, in so doing, improves the steering,” says Albert Biermann, Head of Development BMW M GmbH.

The company says the M3 and M4 completed thousands of laps on the daunting Nürburgring Nordschleife to ensure a race-worthy road car. In doing so, the car is 80 kg lighter, features a “track-specification” cooling system and has an impressive zero-to-100 km/h time of 4.1 seconds with the standard 6-speed auto-blipping manual transmission, or 3.7 seconds with the optional 7-speed dual-clutch automatic.

“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. 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.”
