It looks like the BMW 3-Series Coupe is going out of production as BMW gets ready to release the 4-Series. The 4 series, which will debut at the 2013 Detroit Auto Show, features upcoming a coupe, convertible, and rumored Gran Coupe with a higher numerical designation to signify that they’re that much more special than mechanically related 3 Series sedans. This is part of the overall trend of BMW moving forward with a new naming system that will feature all coupes having an even number.
The 4-Series Coupe Concept is larger than the outgoing 3-Series coupe but still retains familiar design cues including the updated kidney grille and twin circular LED headlamps. BMW has yet to release details on the powertrains that will be available once the concept goes into full production but expect a range-topping M4 with the marque’s new turbocharged in-line six engine.
