Like with North American examples of the coupe, the only available model of the convertible will be the M850i xDrive.
Because the Convertible, at 2,015kg, is 125kg heavier than the Coupe in M850i form, the 0-100kph time of 3.9sec is 0.2sec slower. That's a $9,500 price hike over the M850i Coupe, but for well-heeled buyers who love open-top motoring, it's a small price to pay.
The four-seater cabriolet has a soft-top roof with fully electric operation, opening and closing at the touch of a button and when traveling at up to 50km/h (31mph).
Both combine with a ZF eight-speed automatic transmission and an all-wheel xDrive system.
BMW are expected to make their new 8 Series Convertible at the 2018 LA Auto Show which takes place between the 30th of November and the 9th of December, as soon as we get some more details about the vehicle, we will let you guys know.
The 8 Series Convertible comes with a standard wind deflector that can be placed behind the front seats to cut down on wind curling back to the front row of seats.
Initially two turbo engines will be offered: a 3.0-liter in-line V6 diesel with 320 hp and 502 lbft (681 Nm) of torque (for the 840d xDrive variant) and a 4.4-litre V8 petrol motor with 530 hp and 552 lbft (748 Nm) for M850i xDrive. The electric soft-top roof has an extremely quiet operation that shuts and opens in just 15 seconds up to a speed of 50 kmph. Both cars have a top speed limited to 155mph.
Customers looking for a sportier appearance can order the optional M Carbon Exterior Package. Furthermore, the Bowers & Wilkins Diamond surround sound system adds to the open-air music experience which audiophiles can revel over.
Optional is a night vision system that relays a real-time video image showing people, large animals and other heat-emitting objects. Even when it's tucked away, the roof manages to hew to the overall design of the model: the "double-bubble" contour of the cover behind the two rear seats mimics the design incorporated in the BMW 8 Series Convertible's roofline.
