I think that GM is making vehicles that can run on ethanol or gas. That does not force the buyer to use ethanol. Further I think that GM gets a break on CAFE (corporate average fuel economy) for every car they sell than can run on E85 (or whatever it is called).

So this seems more like a corporation just taking advantage of a loop hole in the economy laws.

But it probably makes them look "greener" to the average person who does not know better.

So mixing the taking advantage of the laws with a good marketing spin is a win-win situation for them, eh?
