GM's BioDiesel hybrid vehicle: When is the concept stage over?

"This unique concept, showcased in a Saab 9-3 Convertible, is the first vehicle to combine a fossil-free bioethanol fuel (E100) capability with electric-only propulsion by utilizing the advanced two-mode hybrid system which General Motors Corp. is co-developing with DaimlerChrysler and BMW Group. The Saab BioPower Hybrid Concept is capable of zero fossil fuel CO2 emissions while also enhancing performance and reducing energy consumption." (more)

To me, such hybrid cars demonstrate the potential that automobiles have to offer - not tomorrow, but today. Sure these vehicles cost more, but how much does it cost the American government to ensure cheap gasoline? I say, enough already GM, get these cars on the road! While I am a huge GM critic, such a vehicle would instantly convert me to a huge GM advocate.
