The BMW M4 was spied at the famous Nurburgring race track during typical test trials.
The F80 M3 and F82 M4 will no longer be powered by the V8 naturally-aspirated engine but rather a new inline-six engine that sources say will develop around 450 horsepower. The new M4 is expected to be slightly faster than the current E92 generation thanks to a lower weight achieved by use of lightweight materials, such as aluminum and carbon fiber.
The BMW M4 will sport an aggressive front bumper with styling cues imported from the 1M and M6 models, as well as a carbon fiber rooftop. The side lines have also been enhanced to give the car a more muscular and sporty look. As expected flared fenders and side skirts are present, along with M-specific wheels. The air vents are large in size with angled fins that give the car not only a road-focused look, but also a dominating stance.
The engine is mated to a double-clutch transmission 7-speed transmission. The U.S. enthusiasts will most likely see a manual transmission option as well.
