A slang term for a small, boxy, fuel-efficient automobile with few luxuries.
Possibly the first econobox was
the Austin Mini, first built in England in 1959.
Other well known economy cars like the Volkswagen Beetle,
Fiat 500 and the
Citroën 2CV are sometimes referred to as econoboxes, but do not have the requisite square shape of a true econobox.
Did you see that
clunky, old
Yugo? If that isn't an econobox,
I don't know what is.
