Impressively, the Gran Coupe really does look like a stretched version of the coupe. The entire front fascia looks almost identical with its sleek lights and wide grille. In fact, the bumper design is practically identical down to the shapes of the creases. Even along the sides, the fender vent and the lines coming off of it are clearly taken from the coupe. And the back has nearly the same taillights and bumper design. Of course the Gran Coupe is a lot longer and has two more doors. This has also led to a bit of departure with the side window design. There's a more distinct uptick in the window sill line, and it ends in a more vertical line that leaves a thicker C-pillar.
We'll see the rest of the exterior and the interior when the 8 Series Gran Coupe is officially revealed next month. Considering how close the exterior is to the coupe, the dashboard design will probably be lifted straight from the two-door, too. Engines will probably be the same as well with the M850i getting a twin-turbo 4.4-liter V8 making 523 horsepower and 553 pound-feet of torque. That engine will be coupled to an eight-speed automatic and all-wheel drive. An M8 version of this and the coupe are likely coming later.
