A 2005 EPA study led by Matthew Brusstar revealed higher engine AND fuel efficiency with E30 than with gasoline:




This is the study's link: www.methanol.org/pdfFrame.cfm?pdf=ISAF-XV-EPA.pdf

A 1.9L 4 cylinder, 4 stroke VW engine with a compression of 19.5 to 1, direct injection, turbocharging was used.

I do not know what current "normal" hybrid engine efficiency would look like on E30.

 

I got an error on your web site link. Do you have a document title we could use for a Google search?

I am always interested in reading original sources since they often include qualifiers and testing methodologies.

Thanks,

There is a thread on this at a different site:

I hope this helps.

 

No problem. The original posting appeared to showa PowerPoint page from some presentation. The paper had more (not enough for me) details and covered the subject. There were a few 'future' reports that were going to cover the aspects that were deferred.

I like the conclusions but some of what they were doing, especially partial power, was a little too vague for my taste.
