You all may have remembered my "Green vehicles of tomorrow" thread. I may have stopped replying to it, but the concepts are by far no means dead. I'm still holding to my opinion that GM should have three "green" vehicles available at all its dealerships.
Here's the first of those three - the SL (Sedan Long) Series. It's a larger alternative to the Prius/FCX - for those who want more room and features.
Like the other "GM" models, this has three powertrains - a 2-mode hybrid system, plug-in electric system, and fuel-cell system.
