The first ever convertible version of the 8 Series nameplate was part of a three-model lineup that found themselves at the very top of the BMW range. The 8 Series name itself has been resurrected in 2018 for the 6 Series replacement.

The classic soft-top roof could be opened or closed in just 15 seconds at driving speeds of up to 50 kph (31 mph) and could be had in either black or silver. Only two engines were available at first, both being paired with an 8-speed automatic transmission and xDrive all-wheel-drive.

The 840d xDrive Convertible used a 3.0-liter diesel with two sequential turbos and has a 320 hp and 680 Nm (505.5 lb-ft) of torque. The M850i xDrive, on the other hand, featured a 4.4-liter twin-turbo V8 gasoline mill with 530 hp and 750 Nm (553.2 lb-ft) of torque.

The interior of the car was very well thought and BMW concentrated on the quality of materials.

The infotainment system consisted of a 10.3 inch touchscreen which was the best on the market at that time. Voice control was standard and the car was equipped with Apple CarPlay. Android auto was not offered.

The seats were very comfortable and were offered with lots of adjustments. Due to their low position and the high window line, the driver did not have as much visibility, however, the car was equipped with front and rear parking sensors, a rear-view camera and LED headlights as standard.
