2019 BMW 8 Series Gran Coupe spied

The BMW 8 Series Gran Coupe has been spied during development testing, giving us another glimpse at the company's upcoming rival to the likes to the Mercedes-Benz CLS and Porsche Panamera. Essentially replacing the current 6 Series Gran Coupe, the 8 Series 'GC' should launch sometime next year and will offer a style-focused four-door coupe alternative to the more traditional 7 Series limousine.
