2014 BMW M4 Convertible spy shots
Coupe-like lines are the first, most obvious detail of the hard-top convertible's shape, with only a slight kink at the rear of the roof taking notable liberties with the Concept M4's lines. At the nose, the M4 Convertible appears to show slightly tamer styling, perhaps indicating the production look of the M4 Coupe as well, scaling back some of the aggressiveness of the Concept M4's air inlets.
At the rear, the M4 Convertible spied in testing compares almost exactly to the concept, at least as far as can be determined through the camouflage.

As for what's under the hood of the M4 line, we expect output of 400-450 horsepower from a turbocharged 3.0-liter in-line six-cylinder known as the S55. Two turbos are almost a certainty; a triple-turbo setup is unlikely. Rear-wheel drive and a dual-clutch transmission are also expected. The possibility of a manual transmission option in the M4 is in doubt. There has also been talk of weight savings for the M4, which would be a welcome change of direction from the 3,700-pound E92 M3 Coupe and nearly 4,000-pound E93 M3 Convertible.
In the meantime, enjoy the sights and sounds of the M4 coupe in action in our spy video.
