BMW 6-Series Gran Coupe unveiled

Takes the fight to the Merc CLS and Audi A7...

BMW has officially unveiled the 6-Series Gran Coupe.

The Gran Coupe is destined to battle the existing market leaders in this segment – the Mercedes CLS and Audi A7. The CLS has had the market to itself for many years, with the A7 coming along a year ago to critical acclaim. Although the exterior styling is very similar to the 6-Series coupe, the Gran Coupe is actually 4.4 inches (110mm) longer, entirely in the wheelbase and in the rear cabin.

The Gran Coupe is a very good looking car, helped by the design of the Coupe. A strong front end style with xenon or LED headlights leads to a swooping bonnet and roofline. At the rear, intricate LED rear lights finish off a stylish yet sporty design. Of course, the main point of the Gran Coupe is that it has coupe-like styling with the practical addition of another pair of doors.

Inside, the cabin is luxuriously appointed with Dakota leather, heated front seats and dual-zone automatic climate control. There's also a "4+1" seating arrangement and a boot that holds 460 litres of luggage. The options are extensive and include ceramic accents for the controls, satellite navigation, a head-up display, radar cruise control, night vision and a powerful Bang & Olufsen audio system.

Under the bonnet, three engines are available. The 640i has a turbocharged 3.0-liter inline-six with 315 bhp and 332 lb/ft of torque. It enables the car to accelerate from 0-62 mph in 5.4 seconds and hit a top speed of 155 mph.

The 650i uses a twin-turbo 4.4-liter V8 with 442 bhp and 479 lb-ft of torque. This allows the car to run from 0-62 mph in 4.6 seconds, before topping out at 155 mph.

Lastly, the 640d has a 3.0-liter diesel engine with 309 bhp and 465 lb/ft of torque. Despite having the least powerful engine in the lineup, the car offers respectable performance as the dash to 62 mph takes 5.4 seconds and the top speed is 155 mph. The killer bit of spec though, is that with that incredible performance the 640d Gran Coupe will achieve 50.4 mpg on the combined cycle and CO2 emissions of 148g/km.

Regardless of what engine is selected, it is connected to an eight-speed automatic transmission. Rear-wheel drive is standard, but all-wheel drive is optional on the 650i and will be available later on the 640d.

Later in the model life there will be an M6 Gran Coupe from the legendary BMW M-Division, powered by the twin turbo V8 recently seen in the new M5, putting out 552 bhp.

Prices will be about £2000 higher than the equivalent 6-series coupé, starting at £61,000 for the 640i.
