2011 BMW 6-Series Convertible Latest Winter Testing Spy Photos

BMW's upcoming 2011 6-Series convertible has once again been spotted undergoing winter testing in northern Scandinavia.

Although the car is heavily disguised, we can clearly see that the new 6-Series will borrow several styling cues from recent BMW models such as the 7-Series sedan, the new Z4 roadster, and the highly praised CS concept. Up front, the new 6-series adopts a more traditional BMW appearance with a wider grille, reshaped headlights, and a more aggressive front bumper. At the rear, the stylized taillights appear to remain intact while the highly controversial "Bangle Butt" seems to have been minimized if not removed completely. As the pictures show, the "fabric" roof fits rather poorly which seems to suggest that the new convertible will ditch the current twin flying buttress soft-top in favor of a new folding metal roof.

Power options will most likely carry over from the current 6-Series, but the 360 hp 4.8-liter V8 engine will be replaced by the new 400 hp twin-turbo 4.4-liter V8 from the recently introduced BMW 750i. So far it's unclear whether or not the M6 will continue to be powered by the current model's V10 engine, with 500 hp and 383 ft-lbs of torque, or if will it have to make do with a slightly retuned version of the 4.4-liter twin-turbocharged V8.
