| Here is the EPA of my Chevy pickup 5.3 L
18 mpg combined @355 Hp
13mpg combined @380 Hp --------a 27.78% drop in mpg but a 7% increase in Hp
The EPA said flex fuel fleet average in the US when power was taken into consideration was 3% better in efficiency, see the bottom of page 7 here:

e85prices.com. These are national prices, states with ethanol plants in them are better along with California.
National E0 price = $2.06
National E10 price = $1.69
National E85 price = $1.48
E0 = $.1144/mile
E85 =$.1138/mile
E10 at E0 mpg(18) = $.0938/mile but the mileage is often said to be less.
Let us use August 2015 prices as an example
National E0 price = $3.02
National E10 price = $2.72
National E85 price = $2.08
E0 = $.1678/mile
E10 = $.1511/mile
E85 = $.16/mile ---------during this time in many states E85 was cheaper to drive.
We need E85 only engines like Brazil and Sweden have which are better than straight gasoline in mpg. Have to have infrastructure first:
FROM CUMMINS ETHOS ENGINE:
According to Cummins, it delivers the power (up to 250 hp) and peak torque (up to 450 lb. ft.) of gasoline and diesel engines nearly twice its displacement...
...Using corn derived E-85, the high thermal efficiency and power-to-weight ratio of this engine results in 50 to 58 percent lower well-to-wheels CO2 emissions compared with the gasoline engine baseline. Using second-generation, lingo-cellulosic derived E-85, the power train’s efficiency features deliver 75 to 80 percent lower well-to-wheels CO2 emissions, depending on the drive cycle.

THE INDY 500:
In 2005, the IRL used 100 percent methanol in their tanks. The fuel worked well and was more efficient than straight gasoline, but IRL officials believed there was room for improvement. In 2006, they moved to a 10 percent blend of ethanol and methanol, which was then changed to 100 percent ethanol for the 2007 season...
...The switch to ethanol also allowed the racers to carry less fuel and make fewer pit stops, thereby increasing efficiency even more. "When the cars ran on methanol tanks had to hold 30 gallons to accommodate the fuel requirements of the cars," Vervynckt says. "After getting the engines to perform at their full potential, there was a significant gain in mileage. Indy cars now have 22-gallon tanks. When a driver pulls in to change out his tires, he can fill up. Teams were able to match their tire and fuel stops exactly, instead of stopping for tires only, or fuel only."
FROM THE EPA:
An important step toward increasing alcohol fuel demand, then, may lie in providing economical engine technology options that utilize such fuels more efficiently, to compensate for the lower fuel energy density. The FFVs produced today, however, use fairly typical gasoline engines, which, because they must retain dual-fuel capability, are not able to take full advantage of the favorable combustion characteristics of alcohols. Engines optimized for alcohol fuel use, on the other hand, may yield efficiencies that exceed that of state-of-the-art diesel engines—or, about one third higher than that of FFV engines. In earlier engine research at EPA with neat methanol and ethanol [1], for example, over 40% brake thermal efficiency was achieved over a relatively broad range of loads and speeds, with peak levels reaching over 42%.
FROM EPA AGAIN:
...These data show that on ethanol, the US FFV fleet averages about a 3% increase in the gasoline equivalent fuel economy on both driving cycles.
FYI, the gasoline equivalent ratio also takes into account the power with the fuel economy.
FROM EPA & FORD ON FORD'S ETHANOL OPTIMIZED ECOBOOST SYSTEM:
Compared to production gasoline engines:
Fuel efficiency is ~15 – 20% improved for various drive cycles.
Full load performance is significantly improved, and comparable to production diesel engines.
FROM RICARDO:
The new federal CAFE standards are calling for a doubling of fuel mileage performance, which, Vint says, is going to send OEM’s looking for high octane numbers to improve efficiency and ethanol is the best source. Ricardo, an engineering firm with over 100 years in the business of engine design, has developed an extreme boosted direct injection engine (EBDI) to optimize ethanol blends. The 3.2 V6 gasoline engine rivals the power and torque of a much larger GMC Sierra 6.7 diesel, he said, and it delivers 3.5 percent better fuel economy than the diesel.
FROM SCANIA:
Scania has a number of products available for running on bioethanol – e.g. buses, trucks and waste collectors. Scania is the only vehicle manufacturer to date that has successfully produced bioethanol applications for heavy transport. Our engines adapted for bioethanol fuel have the same energy efficiency as a standard diesel engine and fulfill the Euro 5/ EEV emission level.

WOW!! E-85
