"Substantial improvements in brake thermal efficiency have been demonstrated with neat alcohol fuels in a cost-effective port-fuel injected, spark-ignited engine configuration. Recently, this work has been extended to include alcohol-gasoline blends, showing significant benefit with fuels containing as little as 30% alcohol. From the results presented above, it is concluded that:
1. Over 40% brake thermal efficiency can be obtained in a high compression ratio, PFI SI engine using neat methanol and ethanol fuels, resulting from the favorable combustion properties of alcohols.
2. Decreasing the fuel alcohol content generally gives lower brake thermal efficiency and somewhat decreased load range.
3. High efficiency was demonstrated with fuel blends down to 30% alcohol content. Such fuels may present a more economical and efficient means of utilizing alcohol fuels, and provide a path toward their more widespread, long-term use."

At last, a reference from this millenium. Nice bit of work too.

Now if only the automakers would build a vehicle with this kind of engine.

Interesting for sure.
