The first-ever four-seat BMW M850i xDrive Convertible, powered by a 523 horsepower 4.4L 8-cylinder turbocharged engine mated to an eight-speed Steptronic Sport transmission, has a fully-electric fabric top roof that can be raised or lowered in 15 seconds at speeds up to 30 mph. The 0-60 mph time is 3.8 seconds to a limited top speed of 155 mph. Active steering moves the rear wheels up to 2.5 degrees in the opposite direction to the front wheels at speeds up to 45 mph. The Driving Experience Control switch enables SPORT and SPORT+ modes for maximum handling along with comfort-oriented ECO Pro and COMFORT modes. The BMW Head-Up Display comes as standard in the first-ever BMW 8 Series Convertible and projects relevant driving information onto the windscreen in the form of graphics. The standard Harman Kardon audio system comprises twelve speakers and a digital amplifier, with an optional Bowers & Wilkins Diamond Surround Sound System. There's an optional M Carbon Exterior Package, consisting of air intake bars, exterior mirror caps and a rear diffuser insert, all made from CFRP. The BMW 8 Series Convertible is equipped with standard Collision and Pedestrian Warning with City Braking function, the latest version of which alerts the driver when a cyclist is detected. Depending on the situation, the system can bring the vehicle to a halt to either avoid a collision or minimize its consequences. The BMW M850i xDrive Convertible arrives in March 2019 with an MSRP of $122,395 (including $995 destination charge).
