High MPG

[M&D]

<Humor>
I, and countless thousands of others, take umbrage to your omission of the
Wankel rotary engine as an alternative to pushrods. (What we call boingers).

Seriously though, although the wankel wasn't very efficient to start with,
Mazda's latest MSP-RE engine puts out like 225HP with 1.3 Liters, and gets
25 MPG or so. Naturally aspirated. Would that they would go into
production...
Anyway, just wanted to put a slant on things.
