The first El Camino was produced for the 1959 model year (two years after the Ford Ranchero) and, like the Ranchero, was based on an existing and easily modified platform, namely the new-for-1959 Brookwood two-door station wagon and corresponding sedan delivery variant; unlike those more pedestrian versions, the El Camino was available with any trim level and drivetrain option corresponding to the car line, including that of the Chevrolet Impala. This was also the first year of the flamboyant "batwing" full-sized Chevrolet which sold in fewer numbers than more conservatively styled Fords. So too did the El Camino suffer in comparison to the Ranchero with 22,246 built the first year. The similar but less flamboyant 1960 model sold even worse at 14,163 units total at which point General Motors decided to discontinue the model. In total, 36,409 first generation El Caminos were produced.
Four years later, with the Ranchero still selling well, Chevrolet reincarnated the El Camino, based on the then-new Chevrolet Chevelle. That 1964 model was basically identical to the Chevelle forward of the B-pillars, but Chevrolet considered the vehicle a practical, utility model and the Chevelle's most powerful engines were not available.
1965 saw the availability of performance versions of the 327 engine with some . 1966 brought added a V8 engine to the lineup rated from 325 to . The 1965 327 would run low 15s in the 1/4 mile (at some 90 mph), while 1966 to 1969 models were easily into the mid- to upper-14s. The El Camino followed the Chevelle's styling update for 1967, with a new grille, front bumper, and trim. Air shocks were introduced, allowing the driver to compensate for a load.
The year 1967 also brought options of disc brakes, Turbo 400 3 speed tranmission and the collapsable steering column for the first time. It was the pinnacle year for the 2nd generation El Camino. 2,565 El Camino Customs came with the 396 big block. That option came with the Powerglide, Turbo-Hydro 400 automatic, manual 3 speed or two choices of 4 speed manual Muncie transmissions. The 396 four speed equipped El Caminos were the most rare with less than 500 units sold.
1968 introduced a longer El Camino, based on the station wagon/4-door sedan wheelbase. A new, high performance Super Sport SS396 version was launched, alongside the Chevelle version. 1969 models were very similar, but 1970 saw the availability of a new SS396 which actually displaced (although all emblems read 396). Chevrolet's largest and most-powerful engine of the time was also put into a select few El Caminos. The LS6 454 in³ engine, rated at and of torque, gave the El Camino 1/4 mile times in the upper 13 second range at almost . 1969 also marked the first time that the legendary Chevrolet 350 V-8 was used in an El Camino.
The 1971 model saw reduced power and performance, along with the rest of Chevrolet's line, as lower-octane unleaded fuel was mandated, and emissions controls began to be felt. Single headlights replaced double for 1971, and the grille came now to a point. Little changed but still lower power outputs for 1972.
A rebadged El Camino called the GMC Sprint debuted in 1971.
For 1973, the El Camino was restyled again, matching changes to the Chevelle. It was the largest generation of El Camino, but thanks to lighter construction, it weighed less than the previous generation. A front-end restyle with quad stacked headlights was done in 1976, but otherwise it was the same truck until 1978.
A new, smaller El Camino was unveiled in 1978, with more sharp-edged styling. With a single headlight design, until a later revision in 1982 that had a four headlight design on the same body style as previous years from 1978 to 1981. The El Camino instead shared components with the Chevrolet Malibu (The Chevelle name had been dropped) and Chevrolet Monte Carlo. V6 engines (based on the Buick or Chevrolet 90-degree V6) were available for the first time, and from 1982 through 1984, Oldsmobile-sourced diesel engines.
After 1984, GM shifted El Camino production to Mexico for three more years. Production ceased after the 1987 model year, as sales of the Chevrolet S-10 true pickup truck were outselling its passenger car counterpart.
1985 to 1987 El Caminos (and its twin, the GMC Caballero) were produced in Ramos Arizpe, Mexico. Around 425 unsold 1987 El Caminos were sold as 1988 models.
On a production note, it has been constantly rumored for years now that GM may bring back the El Camino. During the 1995 model year, GM had a concept El Camino based on the full-size Caprice station wagon using the grille of a 1994-96 Impala SS; this concept was destined for production but terminated due to GM's profitable SUV sales. GM already has a vehicle ready in Australia in the form of the Holden Ute, save for some minor changes necessary to make it available in the U.S. This may have been backtracked within the past couple of years, however, as the Subaru Baja, the only "pickup car" recently available in the US, didn't sell well at all and was dropped after the 2006 model year. In addition, the Pontiac GTO (which Holden built and exported for Pontiac and was loosely related to the Holden Ute) didn't sell well either and was only programmed for three years ending in 2006 due to Holden upgrading the platform it was based on. A Chevrolet badged version, known as the Lumina Ute, is sold in South Africa. It has been recently rumored that the Holden Ute will be brought to the States first as a GMC concept and then as the Pontiac G8ST Now it has been officially confirmed that Pontiac-badged Ute will be brought to USA with first cars coming to showrooms in late 2009 according to Motor Trend.
