And now for the qualifying statements.
The “car” that topped the premium brand leaderboard in 2014 was the 3-Series and 4-Series. That’s the way BMW USA chose to release their sales figures when the 3-Series nameplate divested itself of key assets in the fall of 2013. In a sense then, this is the way it’s always been, since the 4-Series used to be part of the 3-Series family.
• 3-Series hasn’t been outsold in premium category since 2009
• 3-Series/4-Series generate four out of every ten U.S. BMW sales
• 3-Series/4-Series was America’s 16th-best-selling car in 2014
However, the 4-Series lineup has expanded to include very 3-Series-like cars like the 4-Series Gran Coupe even as the 3-Series lineup expanded to include not just a sedan and a wagon but also a hatchback, the 3-Series Gran Turismo.
