Inside, a combination of typical BMW design features and innovative accents gives the new BMW 1-Series a fresh, youthful and modern feel, with a focus on spaciousness and driving pleasure. Lines and surfaces are dynamic and forward-leaning, with high-quality, precision-finished materials reflecting the model's premium specifications. BMW's characteristic driver-friendliness is apparent in the angled displays and controls in the middle of the instrument panel, and the ergonomic contours of the centre console, designed for maximum visibility. The interior surfaces are layered, another innovation which gives the new BMW 1-Series an organic look and feel.

In conjunction with an optional navigation system and the BMW Professional radio, the new BMW 1-Series uses the BMW iDrive system. This comprises a controller on the centre console, favourites buttons and a freestanding flatscreen monitor. The 6.5 or 8.8-inch high-resolution control display, which is integrated into the instrument panel, is used for all information, entertainment, telecommunications and navigation functions.

The new BMW 1-Series also offers much more storage space, with large door pockets, two cupholders on the centre console, a roomy glove compartment, and a compartment under the armrest. Bottles of up to 1 litre can be fitted into the lower door panel sections.

The optional storage package includes large compartments in the rear doors and nets on the front seatbacks. The 360-litre luggage compartment expands to a maximum of 1,200 litres by lowering the 60/40 split-folding rear seats, giving a flat surface extending all the way to the front seats. The optional through-loading system has 40/20/40 split-folding rear seats.
