The two-passenger Super Gnat is proof that small, fuel-efficient cars don't have to look like boxes. Despite its compact 148-inch length and overall height of 48 inches, it has plenty of room inside for six-footers.
In response to the OPEC oil embargo in the mid-1970s, there had been a push for automobile manufacturers to produce smaller, more fuel-efficient vehicles. In the short time following, Ford had studied a two-seater commuter car called the "Super Gnat," which was to have a three-cylinder engine with a short wheelbase. Along with this, Ford also produced a Mustang RSX, a smaller, two-seat derivative of the Mustang.
