A pair of prototype models of the next BMW 6-Series Convertible have been spied on film. The folks over at Bimmerpost that posted the video support that, like the new Z4, the 2011 6-Series Convertible will most likely be equipped with an electric folding hardtop and that for now, the Bavarians are concealing the roof with a faux canvas top.

Unless someone goes and fiddles around with the top, there's no way of being 100 per cent certain, but looking at the creases on the roof, we'd say that these test cars appear to feature a classic fabric top.

In any case, the new 6-Series Convertible will continue to be a four-seater while we suspect that the styling will follow the cautious evolution of the firm's latest models like the Z4, 5-Series and 7-Series, with BMW's designers toning down the flame surfacing and eliminating the so-called Bungle butt.

Under the hood, the new 6er's engines will be sourced from the 2011 5-Series that was revealed last week [...]

The oddly shaped coupe covered in layers of metal and camouflage tape that you see in this spy video undergoing tests at the Nurburgring race track is none other than a test mule for the upcoming Toyota / Subaru co-developed rear-wheel drive sport coupes. Understandably, there's no way of knowing if it's a prototype for the Toyota-badged model that will be previewed at this week's Tokyo Motor Show with the FT-86 Concept or for Subaru's derivative that has yet to be revealed or even named.

Not that it matters as both compact sport coupes will share the same mechanical underpinnings including a modified version of Subaru's 2.0-liter four-cylinder boxer engine said (but not officially confirmed) to produce up to 200HP.

Both the Subaru and Toyota variants of the rear-wheel drive 2+2 coupe are to be produced in Japan at Subaru's Gunma factory with the first examples due to arrive in the market in late 2011.

With the recent introduction of the 2010 Mercedes-Benz SLS AMG Gullwing at the Frankfurt Motor Show, Stuttgart's focus is now on the roadster version that's due in late 2011. Filmed here by the spies at Auto Motor und Sport during hot-weather testing in Death Valley, California, the SLS AMG Roadster appears to be fitted with a traditional canvas top [...]

This 12-second long video hypothetically shows a prototype version of the next-generation BMW M5 sedan that's expected about a year after the introduction of the new 5-Series Sedan and Touring models in 2010. There's no way of being 100 percent sure if it's an M5 or not, but it certainly sounds the part [...]

During a skiing trip to Austria, Carscoop reader Philipp Schmid and his female companion stumbled upon a BMW Group test-car convoy comprised of various future models including Rolls Royce's forthcoming 'baby' limo. Codenamed PR4, the four-door luxury sedan is based on the new BMW 7-Series platform and mechanics and according to sources, it will be positioned between the Bavarian automaker's flagship saloon and the larger Rolls Royce Phantom.

2010 Rolls Royce PR4 Despite the fact that the PR4 is heavily related to the 7-Series, the British firm has said that its entry-level sedan will powered by a new engine, unique to Rolls-Royce - most likely a V12.

Our reader's spy video and photos reveal that the PR4 will carry on many design cues from the larger Phantom, including the rear suicide doors from the Phantom and the high, squared-off shaped roof that helps provide enough headroom for the car's wealthy rear passengers.

"The RR4 has a more informal presence than the Phantom models with a greater emphasis on driving," claims Rolls Royce Chief designer, Ian Cameron [...]

BMW seems to believe that Arctic Circle is not only an ideal test ground but also a perfect playground for its forthcoming X1 SUV / Crossover which is seen here in prototype form fooling around in the snow. If you could magically strip away the X1's psychedelic camouflage, with the exception of a few minor details, what you would get is the production version of last year's X1 Concept that was shown at the Paris Salon [...]
