Did you know that Ethanol optimized engines get better fuel economy than not only gasoline engines, but also better than diesels. They do it cleanly without criminally screwing with the cars computer either.
The US government says even todays inefficient gasoline optimized flex fuel fleet has a higher gasoline equivalent ratio than gasoline by 3%. That ratio takes into account power.

Here are high efficiency ethanol 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.
FROM CUMMINS:
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.

The BTU argument is API propaganda as you can see many engine manufacturers know better.
A diesel engine should never be more than 13.6% better in fuel mileage over gasoline if the claim about fuel Btu is true. Yet we know that diesel engines do get more than 13.6 % improvements in fuel economy over gasoline.
BTU measures heat, not work. that is called the joule. Power is the speed at which a joule takes place. One joule per second is called a watt.
The heating value of 1.25 pounds of wood, a cup of gasoline, and 4 pounds of dynamite are all about the same(7000 Btu)
To show how irrelevant Btu is to getting work done we see that the 1.25 pounds of wood generates 30 kilowatts(.000003 gigawatts), the cup of gasoline generates 3.2 gigawatts, and 4 pounds of dynamite generates 2000 gigawatts. | |
