Badge-engineered from the Chevrolet El Camino, 1971-1987

I have walked among thousands of vintage vehicles at dozens of car shows, but I learned something new today while researching a 1960 GMC pickup. Trolling the GM media archives I came upon an image for a 1971 GMC Sprint.
How had I never heard of this badge-engineered version of the Chevrolet El Camino. Maybe I had just overlooked it in the years of enjoying car shows, but in my defense, surely its production numbers were a sliver of the very popular El Camino.
According to its page in Wikipedia, the GMC Sprint (a coupe utility-pickup) was produced for the 1971-1977 model years. It was renamed Caballero for the 1978 model year and produced through 1987.
“It was identical to the El Camino except for the name. The chassis for both variants was based on the Chevrolet Chevelle station wagon and four-door sedan.
“The vehicles were built on the GM A platform through 1981; for 1982, it was re-designated the G platform as the A platform switched to front-wheel drive.
Difficult Time To Debut
The Sprint’s debut in the early 1970s was not a happy time for performance cars in the United States. It was the first year for mandated lower-octane unleaded fuel, which necessitated a reduction in engine compression. GM’s A.I.R. system, a “smog pump,” was added to control tailpipe emissions.
The GMC Sprint was sold with several engine choices for 1971-72. The base engine was a 145-hp, 250-cubic-inch OHV inline-six. Optional engines included small-block V-8s of 307 and 350 cubic inches and big-block V-8s of 402- and 454-cubic-inch displacements.
“For 1972, horsepower measurements were switched to the ‘net’ figures as installed in a vehicle with all accessories and emission controllers hooked up,” according to the Wiki report. “This change brought the horsepower ratings for 1972 down to a range from 110 horsepower for the six to 270 for the 454 V8.”
The Sprint, sold in trim levels of Standard or Custom, shared exterior and interior trims with the Chevelle Malibu and El Camino. Both years featured rear-end styling taken from the Chevelle station wagon (and were shared with El Camino). The interiors featured cloth and vinyl or all-vinyl bench seats and deep twist carpeting. All-vinyl Strato bucket seats and center console were optional.

The GMC Sprint Diablo package was added in 1978 as an equivalent to the El Camino’s Black Knight (1978) and then the Royal Knight, post-1978, which was an upgrade from the long-running Super Sport package.
The Royal Knight and the Diablo carried a hood graphic in a symmetrical flame pattern that resembled a demon. Diablo also came with lower-body accent paint, body-color mirrors, black-trimmed window frames. Exterior separators also included a front air dam, color-matched steel “Rally” wheels and a large “Diablo” decal on the tailgate.
Sprint SP
The GMC Sprint SP package, only offered on the Sprint Custom, was GMC’s equivalent of the Chevrolet SS package. It was designated as option package, RPO YE7, rather than a distinct model. Engines were an L48 350 four-barrel, LS3 400 (402) big block and the LS5 454 365-hp big block.
