if it does really go mainstream, well then its a good thing a lot of the older Ford vehicals are already FFV cars. (Fuel Flexible Vehical) I think they have been doing that to the Ford Tauras since 2000, so at least there are 6 years worth of older vehicals to that can be used on E85.

Only thing that sucks is the fuel economy on E85 is horrible in comparison to regular 87 octane. Taurus milage goes from 19 city down to 14 city
