E85, according to all relaiable sources of data, gets about 17% - 21% less miles per gallon than gasoline NOT 40% - that is
COMPLETE BULLSHIT.
(of course since Ethanol85 is 19% cheaper than gas kinda makes it all academic anyway, huh?) BUT THATS NOT THE WHOLE STORY - ETHANOL HAS A HIGHER OCTANE RATING THAN GASOLINE (105- 110 for ethanol vs 92 to 93 for PRemium grade gas. With the higher octane, if you are burning ehanol 85 (85% ethanol)
you can use turbo-charging or super-charging to effectively raise the compression in the compression chambers (where the fuel is burned) and get more horsepower and torque than you can with gasoline (!).
That's what Saab did with the
9-5 BioPower FFV. They have computer controlled variable valve timing and turbo-charging,
boosting horsepower 20% and torque 16% over what the engine produces running on strait gasoline.
The result is you get as good or better mileage when running on E85 as you do when using gasoline. Now Saab is owned by GM, so they could make this engine configuration available in U.S. FFVs, but they do not. ( Maybe people should go to the GM web-site and submit feed-back telling them to make this turbo-charged FFV configuration available here in the U.S.)
But what if you have an American FFV without the turbo -charging? Well, at E85 at $2.19 versus $2.69 (or higher) for galsoline that's about 19% CHEAPER for the ethanol! OF course, most of us know what's going to happen to the price of gasoline wehn summer driving season reallly gets goiing. Yes, we'll be seeing $3.00/gal gas. MOre ethanol plants are being built at a feverish pace to try to keep up with the demand. There has been a spike in ethanol prices because Oil companies recently startedd buying eathanol (the fuel they said was too hard to incorporate into their supply system) to replace MTBE. But By the end of this year considerably more production capaciaty will be in place and that should counteract any short term spike in ethanol prices (should they occur - somebody recently posted that he found E85 for 2.19 / gallon so that doesn't show a price spike in his area.).
OF course a FFV doesn't cost the buyer any more than a regular gasoline-only car but if you prefer, you buy a hybrid vehicle and spend $5,000 MORE and wait several years to get your money back.
The moral is, dont' be fooled by horseshit. Look for reputable information sources on the web.
By boosting compression with turbo-charging or super charging you can get better performance and just as good as mileage with ethanol 85 as you can with gasoline, plus you are releasing far less GHG than you would with gasoline. And it's a domestic source of fuel - much better for our economic and strategic security.
