GMC Sprint

The GMC Sprint is a coupe utility/pickup that was produced by GMC for the 1971–1977 model years

. The Sprint was renamed Caballerofor the 1978 model year and was produced through 1987. The rear-wheel-drive car based pickups were sold by GMC Truck dealers mainly in the United States and Canada. The Sprint/Caballero is GMC's version of the Chevrolet El Camino. Trim designations, emblems, and wheel trim differentiate the GMC from the Chevrolet. The GM A platform was downsized for 1978. In 1982, the vehicle became the G platform as the A platform switched to front-wheel drive. In 1971 GMC began producing the GMC Sprint, their version of the Chevrolet El Camino. This light-duty pickup truck was identical to the El Camino except for nameplates, and the chassis for both cars was based on the Chevrolet Chevelle station wagon/4-door sedan wheelbase. Sprint's first year was also the first year for mandated lower-octane unleaded fuel which necessitated a reduction in engine compression, and GM's A.I.R. system, a "smog pump", was added to control tailpipe emissions.
