2014 BMW M6 Gran Coupe brings two extra doors via speedy delivery

Let's clear this up: The BMW 6-Series was launched as a coupe version of the 5-Series sedan. BMW expanded it to include the 6-Series Gran Coupe, which has four doors, but is still a 6-Series. And next year, BMW will bring to these shores the M6 Gran Coupe, which has the 560-hp twin-turbo V-8 from the M6 coupe and the M5 sedan, which is a few inches longer and taller than the M6 and will likely cost far less. Glad we could clarify all that.
