If you know of any efficient vehicle stock that is not listed here, but which should be, please let us know in the comments. Also for stocks in the list that you think should be removed.

Nidec (electric traction motors) Blue Bird (electric school buses), WKHS
Thanks for the suggestions. I used BlueBird and Workhorse, although I added Blue Bird to the list of Alternative Transportation stocks rather than this one. Nidec does not seem to be a publicly traded company.
