hydrocarbon/gallon than any unleaded gasoline engine. the reason
they have a bad reputation is because of poor implementation of
polution prevention devices, especially on trucks, so they smell
awful and make a lot of noise.  I bet you'd drive my Passat and
not even notice it's deisel because its responsive, quiet, and
the pipes run clean.  Then you have to consider that deisel
engines are built like tanks and statistically last hundreds of
thousands miles longer than unleaded engines, making the cost
savings in the end quiet substantial.
