The 2014 BMW M3 and 2014 BMW M4 go to Nurburgring to test their abilities.

With the new generation 3 Series and 4 Series BMW decided to separate the M3 sedan and Coupe. The M3 badge will apply to the four-door model, while the M4 badge will be plastered on the former M3 Coupe designation.

The F80 and F82 M3 and M4 drop the V8 naturally-aspirated engine in favor of a new inline-six engine that sources say will develop around 440 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 M3 and M4 use 80 percent different parts than the 3 and 4 Series models are based on, including a bespoke version of BMW’s new modular engine, a seven-speed twin-clutch gearbox and completely overhauled suspension.

Not confirmed at this point, but our sources say that the new engine will produce around 440 horsepower.
