I miss the long, flowing C pillar of the coupe, but think the convertible looks great in profile, especially with the top up.
Performance figures for both cars are brisk, with the sprint from 0-60mph taking 5.0 seconds in the diesel-powered 840d, dropping to 3.7 seconds in the M850i.
The V8 engine works in tandem with a next-generation 8-speed Steptronic Sport transmission that boasts a wider gear ratio spread; paddle shifters are mounted on the steering wheel.
The M850i xDrive comes standard with a double-wishbone axle up front, a five-link axle in the rear, and BMW's adaptive M suspension. Heck, we already saw convertible mules almost completely uncamo'ed back in September, and the final result is pretty identical to the vehicle in the spy shots.
As most of you know, the original 8 Series (E31) never had a production convertible, despite BMW planning one at one point but chickening out after bean counters realized that the Cabrio was unlikely to recover its development costs. Two oversized connected kidney grilles front a long hood with a short front overhang. With the push of a button located in the center console, drivers can put the top down in 15 seconds while driving up to 30 miles per hour. The Convertible is certain to be dearer than the $300,000-plus Coupe. When the car's computer senses the risk of a rollover, it will automatically deploy two aluminum bars behind the rear seat headrests.
The second feature is a little less serious.
Air vents are integrated into the seats, just below the head rests - like Mercedes-Benz's Airscarf system - allowing warm air to circulate around the back of your neck, which is a godsend on brisk days when you still want to drive with the top down.In addition to the wind in your hair, putting the top down gives you better access to the raucous V8 soundtrack. Roof up, interior noise levels are nearly as low as the Coupe, according to BMW. The passengers are treated to a 10.25-inch media interface with iDrive 7.0, while the driver views a 12.3-inch digital instrument cluster. In comparison, the hardtop will go on sale in December starting at $111,900 before destination. A base price starts at $122,395.
