It's finally here: BMW's four-door-coupe version of a coupe derived from a sedan. If that is a bit confusing, you're thinking too hard. Just go with it.

BMW's answer to a question no one knew to ask, the 2014 4-Series Gran Coupe puts a sleeker, trimmer look on the four-door F30--or adds a couple doors to the two-door F32, looked at from another angle. Whatever angle you approach the new 4-Series Gran Coupe from, however, you're likely to find something worth looking at.

That's right--to our surprise, we completely understand why BMW built this car. It's not that the 3-Series isn't comely enough, it's that the 4-Series coupe's lines translate so well to the four-door format. The result is a strikingly good-looking car that commands attention just as it defies categorization.

Inside you'll find the familiar design and equipment shared with the 3-Series sedan and 4-Series coupe.

The only real difference is in the back seat, where slightly snugger, more bucket-like seats and handy 40:20:40 split-folding seatbacks combine utility and style--with perhaps a bit less headroom than you'd find in a true sedan.

Like its two-door 4-Series coupe counterparts, the 2014 BMW 4-Series Gran Coupe will be available in both 428i and 435i specifications. The 428i gets BMW's 2.0-liter, 240-horsepower turbocharged four-cylinder engine, while the 435i uses the 300-horsepower, 3.0-liter turbocharged in-line six. At launch, the 428i Gran Coupe will also be available with xDrive all-wheel drive. An eight-speed automatic transmission is the sole option on all U.S.-market models, with standard manual-mode paddle shifters and several shift modes selectable via the Driving Dynamics Control in the center console.

BMW says the 428i Gran Coupe will hit 60 mph in 5.7 seconds and achieve gas mileage ratings of 23 mpg city, 35 mpg highway, and 27 mpg combined. The more powerful 435i Gran Coupe runs to 60 mph in 4.9 seconds, and is expected to rate 22 mpg city, 32 mpg highway, and 25 mpg combined.

Though you'd think BMW would have to lengthen the 4-Series coupe to add the extra doors, the 4-Series Gran Coupe shares its overall length, wheelbase, and track width with the coupe.

The only exterior dimensional changes are a roof that's 4.4-inches longer, and 0.5-inches higher for greater rear-seat headroom.

Features, options, and trim lines closely mirror the 4-Series coupe range, with Sport Line, Luxury Line, and M Sport packages available to customize the look and feel of the car.

The 2014 BMW 4-Series Gran Coupe made its global debut at the 2014 Geneva Motor Show. This will be followed by a U.S. debut at the 2014 New York Auto Show. Pricing starts at $41,225 (all prices include destination) for the 428i Gran Coupe; the 428i xDrive Gran Coupe starts from $43,225; and the 435i Gran Coupe will run at least $46,725. Retail sales will start in early summer 2014.
