BMW Vision EfficientDynamics Teaser

As soon as spy images of a mysterious BMW concept emerged earlier this month, BMW said the car pictured was nothing but an old aerodynamics test mule, certainly not a new concept due for debut at the 2009 Frankfurt Motor Show. But whatever that car was, BMW is definitely working on something all-new for Frankfurt, and today the company has released a second teaser image of the upcoming car.

Dubbed the Vision EfficientDynamics concept, it's expected to be a three-cylinder, hybrid-powertrain four-door coupe. Yesterday, the company released a teaser video further developing the car's green image and giving a hint at what looks like a rear quarter panel. The image revealed today, via the IAABlog, shows the opposite view of the other rear quarter panel, which does little to give us an idea of the car's overall shape, but does continue to build curiosity.

Though new video also doesn't show much of the car - beyond the second image above - in any of its green-themed scenes, it does show car-perspective footage, implies high-speed and performance driving and also teases with terms like 'Vision EfficientDynamics', perhaps offering a reminder of the GINA Light Visionary Concept from last June.

The car captured earlier this month offers a similar appearance, though does away with the cloth body work for what appears to be real metal, shaped into a long-coupe profile and apparently small form factor. That shape threw many commentators for a loop in trying to identify the car when it was spotted by spies, but when taken as a possible new model, or at least a concept previewing next-generation BMW powertrain technology, it begins to make more sense.

According to Auto Express, the new car will also show off features of BMW's upcoming design direction, much like the CS Concept did in 2007. That concept drew as much fire as it did praise, and though elements of its design have seen production application - heavily toned down, of course - expect to see another controversial set of features in this new concept.

We'll all have to wait until the Frankfurt show next month to find out exactly what is and isn't rumor, but stay tuned to Motor Authority for the latest developments, whatever they may be.

Late last year a high ranking insider revealed that BMW was working on a “green” super-sports car based along the lines of the M1 Homage concept. BMW development board member Dr Klaus Draeger also recently revealed that the company was planning to unveil a sustainable sports car concept at the upcoming Frankfurt event.

The concept is expected pack the latest in BMW EfficientDynamics technology, but in addition to showcasing powertrain advancements it will also feature sustainable design and material elements.

According to previous reports, BMW is studying the viability of the project, with an eye to eventually building a two-seater sports car that showcases all of firm’s most sophisticated environmental technology. A limited production run would be timed for release at the end of 2012, giving cars like the top-selling Audi R8 and upcoming Mercedes Benz SLS AMG Gullwing some healthy competition.
