Spy Photo – 2015 BMW M4 at Nurburgring

MotorAuthority captured a spy photograph of the 2015 BMW M4 prototype for the first time at Nurburgring. Rumor has it that the F82 M4 Coupe is based on the new 4 Series Coupe and it will differentiate itself from the 3 Series family through a sleeker front apron and slightly redesigned headlights. The coupe roofline gives the car a sleek look which will further differentiate the coupe from the M3 sedan. Based on this photo, the front-end design is said to take its cues from the recently launched M6 and the front bumper is also similar to the M6  but with 1M-like air curtains. It also has large air vents with angled for a more dominating appearance. The rumor says that this vehicle will be powered by an inline-six turbocharged engine with a power output up to 450 hp but this hasn’t been confirmed yet. The BMW M4 is expected to go on sale in 2015, a year later after the sedan version.
