Mercedes Plug-In S-class due for sale in 2012 for those willing to pay extra

Due for sale in 2012, the new S-Class sedan will be offered with plug-in hybrid technology, and eventually this option will be offered across the automaker’s fleet.

The information comes from Mercedes-Benz research and development chief Thomas Weber, who explained to Autocar during a recent interview that it “makes a lot of sense to bundle the high-price tech option to the sort of customers willing to pay for this sort of thing.”
The technology has already been previewed by last year’s Vision S500 Plug-In Hybrid Concept, which combined a 3.5-liter V-6 gasoline engine with an electric motor running on lithium-ion batteries.
