The 28 mpg 2010 Mercedes-Benz S 400 BlueHYBRID will come to the U.S. in Sept. 2009 - but that isn’t the only hybrid the German automaker has in the pipeline for the U.S.

Following the S-Class hybrid, Mercedes-Benz will introduce an E-Class hybrid when the next-generation model arrives in 2010. That will be followed by a C-Class hybrid when the model refreshed in early 2011. In 2012, Daimler will start building between 12,000 and 15,000 electric Smart ForTwos annually. Zetsche said some of those will make it over to the U.S.

“We have decided on hybridization on all of our cars in the future and so far we have had a lot of questions and excitement, but I don’t know how that will translate into a take rate,” Daimler CEO Dieter Zetsche at the 2008 Paris Motor Show.
