The AMC Spirit was a short-lived subcompact 2-door hatchback and squareback that shared the same platform as the Eagle. In fact, virtually all American Motors Spirit parts are the same as the Eagle with the exception of the drivetrain. The Eagle SX/4 and Kammback were all four-wheel drive, and the Spirit was rear-wheel drive. This car was known to be extremely light and very nimble, especially when paired with one of the high-output engines that AMC offered in their Spirit AMX. If fuel economy was your thing, then one could note that the 4-cylinder engine could achieve over 35mpg. With the Spirit's standard 21 gallon fuel tank, that meant approximately 700 miles between fill-ups. A few of these classic vehicles still exist, though they are very rare. Fun fact: a very special Spirit AMX Turbo PPG Indy pace car was built for the 1981 season, equipped with a fuel-injected, turbocharged version of their 4.2L straight 6-cylinder engine that makes 450hp.
