What to Weigh Before Buying

Trim selection changes more than the starting price. The 840i emphasizes rear-wheel-drive grand touring, the 840i xDrive adds all-wheel-drive traction, and the M850i xDrive pairs all-wheel drive with the model's highest horsepower and torque figures.

Fuel requirements and efficiency also differ by configuration. Compare the 17 to 21 city MPG and 24 to 29 highway MPG range with each trim's premium-fuel requirement, acceleration, engine layout, and drivetrain before deciding which version best suits daily driving.

Size and practicality deserve attention alongside performance. The 8 Series Gran Coupe provides 15.5 cubic feet of cargo space behind the rear seats, while its 200.3-inch length and 119-inch wheelbase define its road presence and parking considerations.
