Since the roof is the most important aspect of the sleek creation, lets start with that. Available in black (standard) or Anthracite Silver (optional), the fully-electric folding fabric roof saves weight and space compared to a metal unit, and is claimed to still offer “superb acoustic insulation”. The roof can be opened and closed in 15 seconds at speeds of up to 50 km/h.
When open, the roof is stowed under a cover trimmed and stitched to match the dashboard and doors.
The interior is identical to the Coupe and like the Coupe, there will be two variants offered from launch; one petrol one diesel, both turbocharged.
Headlining the range is the M850i xDrive, which utilises a 4.4-litre twin-turbo V8 putting out a meaty 523 hp (390 kW) of power and 750 Nm of torque. The drop-top can sprint to 100 km/h in just 3.9 seconds making it 0.2 seconds slower than the coupe.
The entry-level variant at launch will be the 840d xDrive, powered by a 315 hp (235 kW) 680 Nm 3.0-litre inline six turbo-diesel. The diesel is no slouch either, hitting 100 km/h from a standstill in 5.2 seconds.
Both engines send drive to all four wheels via an eight-speed automatic transmission, and both have model-specific sports exhaust systems for theatrical soundtracks when you plant your right foot.
South Africa will once again only be getting the M850i xDrive variant which is scheduled to arrive in the first quarter of 2019.
