Say goodbye to the BMW 3-Series Coupe as BMW gets ready to ditch the moniker in favor of the 4-Series. The BMW 4-Series Coupe Concept represent a departure from the 3-Series saloon and estate models and underscores BMW’s new nomenclature system that will see coupes bearing 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.
