The M4 coupe is in the guise of a concept model at Pebble Beach. The CGI M4 convertible from the folks at X-Tomi Design is as close as we'll get to an actual model when and if it goes on sale in markets around the world by 2015.
The 4-Series Convertible will be formally introduced later this fall, and the open top M4 will feature a three piece electric folding metal roof. Power will come from the 3.0 liter turbocharged six delivering the same output as the outgoing M3's naturally aspirated V8. No other information available for the moment.
