New photos of new 2012 BMW 6 Series Convertible emerge from the UK. Shown here are the 640i and 650i high-end cabriolets in Deep Sea Blue and Vermillion Red. The 640i is powered by the N55 TwinScroll turbocharged engine. The engine produces 320 horsepower at 5,800 rpm and 450Nm of torque between 1,300 and 4,500 rpm. The 640i Convertible weighs 1,840 kilograms, but still manages to run from 0 100 km/h in 5.7 seconds.

Fuel consumption is impressive for a car of this size, 7.9 liter per 100km, approximately 29.7 US MPG. Compared to the 650i model, the 640i sports a pair of round tailpipes instead of the oval ones.

The 650i Convertible uses the same engine as in the 550i, 750i or the 550i GT, a 4.4-liter V8 twin-turbo powerplant that produces 400 horsepower between 5,500 and 6,400 rpm and 600NM of torque (450 lb-ft torque) between 1,750 and 4,500 rpm.

The engine is mated to a ZF 8-speed Sport Automatic gearbox, but a manual option is offered as well. The car weighs 1,940 kilograms and sprints to 100 km/h in just 4.9 seconds, a performance similar to the current M6.

The US market initially receives the 650i model, followed a year later by the 640i. The stunning, all-new 2012 BMW 650i Convertible will start at $91,375. To read more about the driving experience aboard the 6 Series Convertible, feel free to click through for our own test drive.
