BMW has revealed their challenger to the second generation Mercedes CLS, which has since been joined by a host of other premium car maker namely in shape of Audi A7. The extension to the current 6-Series range originally started its life as the BMW Concept CS in 2007, and subsequently appeared in almost finished form in Beijing Motorshow as BMW Gran Coupe Concept in April 2010.
The new Gran Coupe is described as an addition to the 6 Series Coupe, already a stunningly proportioned car with 4 door and added passenger capacity of up to 4+1 seater. To accommodate the afore-mentioned added capacity, the Gran Coupe is 112mm longer than the 6 Series Coupe at 5,007mm. Width remained at 1,894mm while the height of the car increased by 27mm to 1,392mm. The wheelbase extension is almost similar as the length extension at 113mm, bringing it to 2,968mm, similar to current BMW 5-Series F10. It is no surprise that all these cars, including the current 7-Series do actually share a huge commonality in their platform. The increase in length over the Coupe/Cabriolet sibling also brings an accommodating 460l of boot space.
BMW 6 Series Gran Coupe is powered by the series of familiar contemporary BMW engines. All powertrain are hooked to the 8 speed automatic transmission. The base model 640i is powered by the updated N55 3.0l straight-six, Twin-Power turbocharged engine, dubbed N55HP. In this application, the powertrain delivers 315bhp@5800-6000rpm and 447Nm@1300-4500rpm of power and torque respectively. Paired to 8 speed automatic transmission, 640i is capable of 5.4 seconds century sprint and a restricted 250 km/h of top speed. Fuel efficiency is quoted as 7.8l /100km.
