We've known for a while that BMW was planning to turn its new 4 Series Coupe into a sedan. But wait, isn't that car the 3 Series? Yes, but now BMW is taking this platform one step further with the new 4 Series Gran Coupe. Call it a four-door coupe that'll be slightly more expensive than the 3 Series. While the interior and overall mechanicals are identical to that of the 3 sedan, the 4 Series Gran Coupe is longer and wider by nearly a half an inch, yet it's still an inch and a half shorter in height.

That translates into being lower, sleeker, and wider, exactly what a four-door coupe is supposed to be. BMW hasn't yet announced official interior volume numbers, but they shouldn't be all that different than the 3 sedan. But nobody who wants a four-door coupe will care about that. The 4 Series GC also benefits from more sculpted front and rear ends you'll find on the 4 coupe. BMW also claims the car's appearance is derived conceptually from the uber sexy 6 Series Gran Coupe. Under the hood and you'll find the exact same engines from the 3 and 4 Series: a standard 2.0-liter turbo four and an optional turbo 3.0-liter inline-six. An eight-speed automatic gearbox is the sole transmission offering.

BMW's xDrive all-wheel-drive system is optional. The 428i model will run $3k more than the 328i and the 435i is an extra $2,400 over the 335i. An official live debut will happen this March in Geneva and sales will begin this summer.
