It has not been confirmed by Porsche yet, but the word on the street is that the German sports car maker will unveil a new and unusual version of the 911 at the upcoming Frankfurt Motor Show in September. It is called the Blu Edition, and it is said to be the most environmentally friendly 911 ever.

Distinguished by a rather ridiculous paint job of blue body and red accents on the bumpers, mirrors, and the roof, this convertible 911 features removable hardtop made form lightweight materials instead of a folding one. The roof weighs only 22 kg, and is the main weight saving measure Porsche has taken to make this 911 more fuel efficient.

Another measures include a set of lightweight 18-inch wheels with hollow spoke, an active grille shutter system, a stop/start function and an alternator that disengages form the engine when it’s not needed. The 3.4 liter flat-six engine is also detuned by 50 horsepower. All that results in an average fuel economy of 6.4 liter/100 km, equating to 152 g/km CO2. The 911 Blu Edition can accelerate from 0 to 100 km/h in 5.4 seconds.

The specs of the 911 Blu suggest that it should be a concept car to showcase how efficient a 911 can be. But sources suggest that it is indeed a production model, and will cost 75,000 Euros when it launches.
