For the Detroit Auto Show in January, Mercedes plans to give the world a preview of three fuel-saving systems for its new entry-premium model range, which should replace the B-class by 2010. Known as Concept Blue Zero, the technology will be shown in forms ranging from a purely electric car, a plug-in hybrid, and as a fuel cell model. The electric model “E-Cell” will have a 100-kilowatt motor with a lithium-ion battery pack and a range of around 60 miles. The plug-in hybrid on the other hand will feature a three-cylinder gasoline engine with an electric generator to extend the car’s range in electric mode (similar to what General Motors plans for the Chevrolet Volt).

The third model called the F-Cell, will use a fuel cell and hydrogen tanks to produce the necessary electricity. Mercedes’ plan is to replace the B-class and A-class with four cars, which include a coupe to compete with the BMW 1-series, and also an SUV to rival BMW’s upcoming X1. These replacements are slated to be built in Restart, Germany, as well as in Kecskemet, Hungary where M-B will open up shop by 2010.

Have a look at the full press release for Concept Blue Zero below and take a look at a few images of the car in our attached gallery. Stuttgart – Mercedes-Benz is showing the way ahead in environmentally responsible electro mobility by presenting its near-series Concept Blue ZERO at the North American International Auto Show in Detroit. Based on a single vehicle architecture, this intelligent, modular concept allows three models with different drive configurations, all of which are able to meet customer requirements in terms of sustainable mobility.
