I have been talking to a guy on another forum who owns a FlexFuel Avalanche and his fuel economy on E85 is somehow the same as it is on gasoline. Don't ask me, I don't understand either. (I can think of a few ways to squeeze out the extra MPGs but I don't know what if any GM is using.)

I think we'll have to give the industry(s) more time before we see it. If we really are headed to an ethanol infrastructure we won't get the variety of vehicles until more people have access to the fuel, which won't happen until people have vehicles, which...ack. Let's just say there's a reason it hasn't happened yet. The good news is that the vehicles are in development, and exist in places such as Brazil. Saab, for example, has developed a 4-cylinder turbocharged powerplant that runs on gas but runs better on ethanol. More power and equivalent FE despite the slightly lower energy density of the fuel. Wanna run lean? How about increase your compression ratio to 12:1? You can do those things since the octane rating is so high.

If it's going to happen it will be worth the wait, I think.
