BMW has revealed its new 8 Series in droptop guise and it's the second member of the new family that replaces the previous 6 Series range, and which will also eventually include a four-door "Gran Turismo" model.
The 4-seat BMW M850i xDrive Convertible is powered by an updated 4.4L 8-cylinder turbo engine set within an advanced chassis; the powertrain delivers 523 hp and 553 lb-ft of torque. The drop-top flagship accelerates from 0 to 100 km/h (62 mph) in just 3.8 seconds.
The convertible's styling is almost identical to the coupe, except for the electrically folding soft top.
The 8-Series Convertible's automatic soft-top roof features multiple layers to keep the noise and weather out of the 2+2 cabin. The model also features standard Icon Adaptive LED Headlights with LaserLight technology that are the slimmest headlights of any BMW model to date. Both versions will not only use xDrive, BMW's intelligent all-wheel drive system, they will be equipped with an eight-speed steptronic sport transmission. After all, the M4 with the Competition Package is just as fast, and people buying this vehicle won't necessarily go drag racing with it.
The M850i xDrive convertible also got an electronically controlled rear differential lock, which is optional on the 840d xDrive version. The multi-layer fabric roof available in two colors opens in 15 seconds at the touch of a button at speeds up to 31 miles per hour (50 km/h). That's because additional reinforcement is required to make bodies of convertibles stiffer than their coupes stablemates.
You will have to pay extra for winter-proofing in the form of BMW's headrest-mounted neck warming system. When the auto detects a rollover, the system can extend two aluminum roll bars from behind the rear headrests in a fraction of a second. 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 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.
