Chevrolet introduced its new El Camino model in 1959. Originally based on the Impala, the half car, half truck El Camino survived for only two years, but reappeared in 1964 based on the Chevelle.

 

This new El Camino shared most of its traits and powertrains (including high performance engines) with the Chevelle. SS versions would debut in 1968 and establish the El Camino as a muscle car/truck.
