Over the two-door M6 models, the four-door adds ‘four plus one’ seating, electric rear and rear-side blinds and quad-zone climate control air conditioning. Other equipment includes 20-inch alloy wheels, an part-Alcantara headlining with a leather insert and a rear diffusor made of carbonfibre.
The M6 Gran Coupe shares its 4.4-litre twin-turbocharged V8 engine and seven-speed dual clutch transmission with other M6 models and the M5. Producing 412kW of power and 680Nm of torque, BMW claims it will run 0-100km/h in 4.2 seconds.
By comparison, the Mercedes-Benz CLS63 AMG produces 386kW/700Nm, is two tenths slower to 100km/h, only seats four, but is cheaper at $263,000. The Porsche Panamera GTS is a tenth slower again and costs $318,300.
BMW Australia says since the launch of the 6 Series Gran Coupe in July 2012, the four-door has overwhelmingly been the best selling bodystyle, capturing almost half the total 6 Series sales. It expects the M6 Gran Coupe to follow that lead, with 15 orders already taken for the four-door flagship.
