Over on biodiesel.infopop.cc there is a link to
www.centaurus.de regarding a newly introduced German motorcycle with a two cylinder diesel motor. It is a full size cycle, not a heavy moped like some of those British army Enfield cycles (still in production in India), but seems geared for acceleration rather than top end (c. 125 kph) and gets 94 MPG!
Of course, as a classics professor, I should now bore you with a lecture on the differences between the good Centaur of Greek myth (Chiron, the Greek equivalent of Yoda, aka the original Child Care Centaur) versus the bad centaurs, but I won't. You can just refer to the recent book, _The Centaur's Smile_, on the various mythic monsters of the eastern Mediterranean.
