The Cadillac El Caminois a concept that was built in 1954. It was a driveable, two-seat show car first shown at the 1954 GM Motorama. It had a fiberglass body and a brushed stainless steel top, which was a preview of Cadillac styling later that decade. The passenger compartment used a curved glass, aircraft-type bubble canopy.
It was powered by a Cadillac 230 horsepower overhead valve V8 engine. The El Camino had an overall length of 200-inches and an overall height of 51.6-inches and was painted a pearlescent silver color. The interior was covered in gunmetal gray leather and the steering column, horn button and ring were chrome plated. High backed bucket seats were built into the headrests that flowed back to the rear window.
Several styling cues, such as the shape of the rear fins, the stainless roof, fluted side panels, gull-wing front bumper and quad headlights would show up in future production models.
There was a convertible concept very close to the El Camino called La Espada. The El Camino name, translated in Spanish means "The Royal Highway", was later used on Chevrolet/s car based production pickup introduced in model year 1959.
