2019 BMW 8 Series Gran Coupe (officially) revealed

After leaking in detail last week, the BMW 8 Series Gran Coupe has been officially revealed in full. The four-door coupe (or should that be sloping-roofed sedan?) takes the 8 Series and stretches it in every direction. It has a wheelbase 201mm longer than the two-door, and the body is 231mm longer in total. It's also 30mm wider than the regular 8 Series. In other words, she big.
