Oh, OK then. Maybe it's just because Honda doesn't think diesels will sell.  
Most non-fleet passenger car diesel sales the world over are driven by
government tax policy that's used as covert social engineering. Canada and
the US do not make such a distinction, so there's little difference between
diesel and gasoline here.

My wife (and most other women I know) absolutely hates diesels on account
of the stink of the fuel. She'll never buy one. And she doesn't even do her
own fillups.

Chrysler brought out the diesel Jeep as a PR measure to make the enviros
happy. If the engine makes any money for them, it will be European sales
that do it, not American ones. European sales are driven by government tax
policy that taxes diesel far lower than gasoline.

Mercedes has been strongly associated with diesels since at least the
1950s, so it's a staple for them. Mercedes diesels are your basic everyday
taxi to most of the rest of the world, and they've sold millions upon
millions to fleet markets for decades.

As for VW, they've managed to turn their diesels into status symbols, Lord
knows how. Clatter clatter, stink stink. Not for me, thanks.
