The leaf emblem the original poster is irked to see on some non-hybrid Fords denotes FFV -- a
Flex Fuel Vehicle (eg. one that can run one normal gasoline and, say, ethanol.) It's just the leaf and road logo--it does not say HYBRID.
I find it comical that someone would actually put the emblem on a non-hybrid or non-FFV, so much so that I think our single-post-to-his-name diesel F350 driver is pulling everyone's leg. For one thing, the badging is so small I'd wager 99.9% of people don't see them anyway... only other hybrid drivers really notice them, because they're typically looking for "kin" on the roadways. I mean really, do you notice every Mustang GT vs. non-GT Mustang, or every Dodge HEMI vs. non-HEMI pickup?
