Expert Reviews

Expert reviews: 

It may be difficult to put a label on the 2018 BMW 6 Series Gran Coupe, but there's no question about the level of performance and luxury it brings to the table.The 640i is powered by a turbocharged 3.0-liter inline-six (315 horsepower and 330 pound-feet of torque) matched to an eight-speed automatic transmission with steering wheel-mounted shift paddles.

PROS
Modern interior is trimmed with excellent materials
Distinctive styling for a sedan of this size
Smooth, effortless power from either engine
Lots of standard features

CONS
Backseat is more cramped than in similar coupe-styled sedans
Not as quick as some rivals, regardless of engine
More expensive than most competitors
