BMW released today the first presentation clip for the new 4 Series Coupe concept, which will go into production sometimes next year. The BMW 4 Series coupe is longer and wider than the current 3 Series, which means it offers more interior room for its passengers, and more luggage space. BMW plans to offer the production version of the 4 Series as a coupe and as a convertible. If we get lucky, we'll also see a BMW M4 in the following years.
