The driver-oriented cockpit layout familiar from BMW models down the years and a dynamic forward-surging movement define the design of the interior. The centre section of the instrument panel - including the Control Display, the central air vent and the controls for the audio system and climate control - is angled slightly towards the driver. The gearshift lever is located on a surface that opens out towards the driver and is set lower than the front passenger side of the centre console. This structure is repeated in the central section of the instrument panel, further enhancing the driver-focused feel. The fluent transition between the centre console and instrument panel can be accentuated with optional stitching in contrasting colour for the leather surfaces.

The horizontal structuring of the instrument panel is accentuated by an electroplated strip on the driver's side of the cabin. This is extended into the front-passenger side in the form of a subtle crease in the glove compartment. Meanwhile, powerfully taut waistline surfaces - which are carried forward into the instrument panel - embody the feeling of dynamic forward movement inside the cabin. The decorative surface of the instrument panel extends into the centre console with an elegant, slightly curving sweep to lend the front-passenger side an exclusive allure.

The rear seats also provide their passengers with a very pleasant level of touring comfort thanks to their individual-seat character and greater shoulder and elbowroom compared with the outgoing model. In addition, there is also more headroom for all the passengers, despite the reduced overall height of the car. The rear seat backrests can be specified as an option with a through-loading facility for a ski bag, allowing two pairs of skis to be transported in comfort. The luggage area can accommodate 460 litres (16.24 cu. ft) of luggage, which means that the BMW 6-Series Coupe can carry three 46-inch golf bags or two medium-sized hard-shell cases plus a flight case.
