Page 1 of 1 Thanks to its new side fin roof, the 6 Series Convertible, like the 6 Series Coupé, stands out through its sheer presence and elegant lines - the fins offer the same visual effect as wide C-pillars, with a coupé-like look. And with the roof down, the Convertible clearly reveals its unique character, skillfully combining the athletic attributes of the sporting Coupé with styling elements of a luxurious 2+2-seater Convertible. At very first sight, therefore, the new Convertible offers a glimpse of the exceptional driving agility so typical of the BMW 6 Series.
The Convertible enters the market in the guise of the top-of-the-range 4.4-litre 8-cylinder BMW 645Ci. Maximum output is 333 bhp, maximum torque 450 Newton-metres. Infinite adjustment of virtually all relevant parameters such as valve timing (bi-VANOS), valve lift (VALVETRONIC) and the length of the intake manifolds enables the engine to adjust perfectly to all demands and requirements.
Ideally combined with one of three six-speed transmissions available on the new model - among them BMW's well-known SMG Sequential Manual Gearbox carried over from Formula 1 and controlled by buttons on the steering wheel - the 645Ci Convertible offers a standard of driving performance only very few sports cars are able to match.
The newly developed roof clearly underlines the practical qualities of BMW's new Convertible: The noise- and heat-insulating layer made of PUR plastic between the rubberised outer layer and the inner lining dampens exterior noise just as effectively as it braves the wind and weather. The result is a very low noise level within the 6 Series Convertible, allowing relaxed conversation within the car even at high speeds.
The vertical rear window between the fins on the roof is made of glass and is electrically heated. As a further feature, the rear window can be retracted completely into the luggage compartment bulkhead by means of an electric motor with the roof both open and closed. This creates a draught-free ventilation effect similar to that offered by a sliding roof in a saloon. Page 1 of 1
