The interior has a 2+2 seating configuration with small rear seats, though BMW says those seats get more legroom than the previous generation. Headroom has also increased in the front and rear. Trunk volume in the coupe is about 30 percent more than the convertible with its top up; with the top down, the convertible loses another 14 percent. An optional pass-through to the cabin, fitted with a ski bag, comes in an optional Cold Weather Package, along with a heated steering wheel and heated front seats.

The front power seats have 10-way adjustment, and ventilation and massage features are optional. Navigation and other features are controlled through the standard iDrive system, which includes a 10.2-inch high-resolution screen on the dashboard.
