There’s a new BMW model in development, and while it looks a bit like the 3-Series that’s been on sale for the past two years, it’s actually an entirely different vehicle. The new BMW is the 4-Series Gran Coupe, which will be landing in showrooms later in the year as a 2015 model.

The 4-Series Gran Coupe is essentially a smaller version of the 6-Series Gran Coupe and fits into the burgeoning four-door coupe segment instigated by the original Mercedes-Benz CLS-Class. We’ve been spying prototypes for months, and soon the covers will come off as the car is slated for a debut at the 2014 Geneva Motor Show in early March.

The 4-Series Gran Coupe is said to feature the same overall length and wheelbase as the 4-Series coupe, but with a taller roof. As the prototype in this latest spy video reveals, designers have shortened the length of the 4-Series coupe’s doors in order to accommodate the rear doors. You’ll also note that the 4-Series Gran Coupe appears wider and more planted than the 3-Series sedan, especially from the rear, helping to set the two apart.    

As for the engine lineup, expect the same 428i and 435i designations from the 4-Series coupe to filter across to the 4-Series Gran Coupe. This means a 240-horsepower 2.0-liter turbo in the 428i Gran Coupe and a 300-horsepower 3.0-liter turbo in the 435i model. Transmission choices should include a standard six-speed manual and optional eight-speed automatic.

A high-performance M4 Gran Coupe powered by the 425-horsepower 3.0-liter turbo announced for the latest M3 sedan and new M4 coupe is possible, along with a sporty M Performance model.
