BMW announced that the third generation of its GT model, the 6-Series Coupe that was launched last April at the Shanghai Motor Show, is now available to order in the UK with sales starting on October 15.

The 2+2 luxury coupe will be offered with three engine, including two gasoline units and a turbo diesel, all fitted with BMW’s fuel-saving EfficientDynamics technology.

The 640d, which is expected to account for nearly 90% of all 6-Series UK sales, is powered by an in-line six-cylinder twin turbocharged diesel engine delivering 313HP and 630 Nm (464.6lb-ft) of torque that are transferred to the rear wheels via an eight-speed auto gearbox.

It accelerates from 0-62 mph (0-100 km/h) in 5.5 seconds and reaches an electronically-limited top speed of 155 mph (250 km/h). Despite the performance, average consumption is just 51.4 mpg UK (5.5 lt/100 km, 42.8 mpg US) and CO2 emissions don’t exceed 145 g/km.

Buyers who prefer their 6-Series to be powered by gasoline have two options: the 640i and the 650i, both of which are offered solely with an eight-speed automatic transmission.

The 640i Coupe is powered by a 3.0-liter turbocharged in-line six-cylinder producing 320HP and 450 Nm (332 lb-ft). It accelerates from 0-62 mph (0-100 km/h) one tenth of a second faster than the 640d at 5.4 seconds while the electronic watchdog makes sure that the top speed 155mph. Naturally, it’s less fuel-efficient than the diesel, with an average consumption of 36.2 mpg UK (7.8 lt/100 km, 30.1 mpg US) and it emits 181g of CO2 per km.

The top-of-the-line 650i has a 4.4-liter eight-cylinder under its bonnet. Thanks to the two turbochargers, it develops 407HP and 600 Nm (442.5 lb-ft), allowing the coupe to accelerate from a standstill to 62 mph in 4.9 seconds and reach an electronically limited top speed of 155 mph (250 km/h). Fuel consumption is 26.5 mpg UK (10.6 lt/100 km, 22.0 mpg US) and CO2 emissions stand at 246g/km.

All versions of the 6-Series sold in the UK come as standard with Dakota leather upholstery, electric seat adjustment with memory, BMW Professional Navigation, Xenon headlights and LED front fog lights, front and rear parking radar and 18-inch alloy wheels (19-inch for the 650i).

The optional M Sport specification adds M-Division’s aerodynamic package, high-gloss “Shadowline” exterior trim, black brake calipers, 19-inch M alloy wheels and dark chrome exhaust pipes on the exterior, while the interior features sports seats, M Sport steering wheel, anthracite headling and aluminum trim.

Of course, there will be a long list of optional equipment including night vision with pedestrian recognition, lane change departure warning system and a Head-Up Display.
