The interior of the new 6-series convertible is distinguished by smooth flowing lines, powerful and stressed surfaces and a very attractive combination of convex and concave design elements. The controls of the air conditioner, audio system and navigation system are within optimal visibility and within the reach of the front passenger. Some controls and switches, including door handles and gearshift lever, are finished with exquisite pearl-gray metal, which provides excellent tactile sensations and an elegant appearance.

The side panels show a smooth and fast-paced design that extends from the dashboard to the backs of the two rear seats. The center console also extends to the rear, serving as a storage box between the rear seats. The interior lighting installed on the doors and rear side panels creates the effect of warm and indirect light.
