Is BMW making their lineup more confusing or more distinctive? Hard to say. As rumored several years ago, BMW is finally doing away with their 3-Series coupe nomenclature and making their 2-doors consistent with even-numbered badging, a la 6-Series. The all new BMW 4-Series Concept reveals what the coupe version of BMW’s segment-leading, bread-and-butter 3-Series will look like when production begins: all signs point to a sweeter execution than its odd-numbered sedan brethren.

The 4-Series’ sheet metal looks to be even more gorgeously sinewy than the 4-door, and its body is longer, wider and shorter, lending to a more aggressive look and elegant stance. Most noticeable are the front fascia and rear vents, which look nothing like any current Bimmer; an all-new front quarter panel vent seems to mimic the front and rear. The engines from the current 3-Series sedan — a 2.0 liter turbo four-cylinder and a 3.0 liter turbo six-cylinder — should carry over into the 4-Series. Interior design is BMW-opulent, with many of the same tech toys as the bigger and pricier 6-Series. Whether they number it odd or even, Munich has carved out a nice new toy for both driving enthusiasts and well-off individuals who like to be seen in something tasty. Look for its debut at the North American International Auto Show in Detroit in January of 2013.
