Jaguar built an electric XJ last year, Rolls-Royce showed off an electric Phantom this year, now Autocar reports that Mercedes is open to considering an electric offering. To be precise, Autocar said such an S-Class "is not being ruled out" and that Mercedes' technical head Thomas Weber said, "We are looking at customer demand." All that really means is that it's on the table, probably alongside a whole lot of other things that might or might not ever happen.
However, Mercedes is part-way there with its S400 Hybrid, and the next S-Class due in 2013 will add a plug-in hybrid option. Until then it'll be up to Fisker to – eventually – bring ionized motoring to the luxury sedan masses.
