BMW teases 8 Series Gran Coupe

"Stay tuned. More to come in Geneva next week."

BMW appears to have released an official teaser sketch for the rumored 8 Series Gran Coupe.

The image shows a large four-door model with an even sleeker profile than the 6 Series Gran Coupe, though it may not be a precise representation of the production car's final form.

BMW's choice to tease a sketch rather than a photo suggests a concept or design study will be revealed next week in Geneva.The two-door 8 Series coupe is expected to arrive on the market before the end of the year.
