For 2011, the new BMW 6 Series Convertible is a car that offers its drivers a unique blend of distinctive styling, luxury and sporting performance. The BMW 6 Series Convertible features an even more powerfully contoured roof while the sweeping bonnet, set-back passenger compartment with Hofmeister kink, long wheelbase and flat waistline embody more than any other BMW the key design DNA of the marque.
Two exceptional BMW turbocharged petrol engines, a newly developed chassis and a host of class-leading driver assistance technology ensure the new BMW 6 Series Convertible isn't all show and no go, while interior space and comfort has been enhanced.

The new BMW 6 Series Convertible is available from launch with two petrol engines: the BMW 650i and BMW 640i. Both offer unique character from their respective V8 and inline six-cylinder engines through the use of twin and single turbocharger technology to produce even more responsiveness and flexibility, exceptional smoothness and efficiency and, of course, high power levels.
The 4.4-litre eight-cylinder engine in the new BMW 650i Convertible is unique in that the brace of turbochargers are positioned in the V-shaped area between the cylinder banks. This design results in more efficient packaging and greater engine efficiency. A maximum 407hp is developed between 5,500 and 6,400rpm, with peak torque of 600Nm available between 1,750 and 4,500rpm.
The new BMW 650i Convertible sprints from zero to 62mph in 5.0 seconds, with a top speed electronically limited to 155mph. For a model of such blistering performance and refinement, it is also extraordinarily efficient, with average combined fuel consumption of 26.4mpg and CO2 emissions of 249g/km.
The six-cylinder in-line engine in the new BMW 640i Convertible uses single turbocharger technology alongside petrol direct injection with VALVETRONIC fully variable valve control.
This enables the 3.0-litre unit to develop a maximum 320hp at 5,800rpm and maximum torque of 450Nm between 1,300 and 4,500rpm. This engine propels the BMW 640i Convertible from zero to 62mph in 5.7 seconds and on to an electronically limited top speed of 155 mph.
Perhaps even more remarkable are its efficiency figures. The BMW 640i Convertible achieves 35.8mpg on the combined cycle, while CO2 emissions are only 185g/km, proving that at BMW luxurious sporting performance does not come at the expense of economy. Indeed, this model is fitted as standard with an automatic transmission that features Auto Start-Stop technology and an automatic active air flap control behind the car's kidney grille for optimum engine performance.
As with all BMWs, both derivatives of the new BMW 6 Series Convertible come with a raft of BMW EfficientDynamics measures to reduce fuel consumption and emissions. In addition to the features highlighted on the BMW 640i Convertible, both models have technology such as Brake Energy Regeneration, Electric Power Steering (EPS), the need-based operation of ancillary components and intelligent lightweight construction to ensure maximum efficiency as standard.
An eight-speed Sport automatic gearbox is standard fitment on both BMW 6 Series models, and its wide range of ratios offer a perfect balance of muscular, sprinting performance, refined high speed cruising and low speed efficiency.
The BMW 6 Series Convertible goes on sale in the UK on 26th March 2011. Prices will be announced at a later date.Published 18 November 2010
