I'm not sure where you're getting the fuel economy drop from that link - it deals with E10 vs E85, where there's about a 30% drop (significant, but far less than the change in gasoline volume).
- sliverstorm 14y agoI'm curious to see how things change when you use an engine designed specifically for E85. I'm told ethanol behaves a lot like high-octane gasoline, which means an engine built for ethanol could have greatly increase compression, which can improve economy. Alternatively, you can run much higher boost, which I believe can directly improve efficiency, or can simply be combined with a very small engine.
