Cadillac Models & History 1976

From the beginning, Cadillac had been nearly synonymous with luxury. People spoke of countless products as “The Cadillac of (whatever).” Through the tailfinned postwar years, Cadillacs had been poshly (sometimes gaudily) appointed, gargantuan in size, powered by some of the biggest V-8s around. Owning one was viewed as a milepost, a demonstration that one had “arrived.”

As the 1976 model year began, signs were already appearing that change was imminent; that Cadillac’s position might even be in jeopardy one day. For the moment, though, little had changed. Only Lincoln competed in the domestic luxury market, as Chrysler had abandoned its Imperial. Beneath all full-size Cadillac hoods was the biggest V-8 of modern times: a 500 cu. in. behemoth, fully appropriate for the car’s enormous length. On the other hand, during the ’75 model year a much different kind of Caddy had emerged: the compact Seville, powered by a comparatively tiny, fuel-injected 350 V-8. Unlike the soft American ride and slushy handling typified by big Cadillacs, Seville delivered control more appropriate in a European sedan.

Amid massive publicity, the final front-drive Eldorado convertible came off the line in ’76, selling for astounding sums to speculators before levelling off. The bottom-ranked Calais was in its final year, soon to leave only Fleetwood and DeVille to attract full-size coupe/sedan devotees. Luxury-minded customers had plenty to choose from, however, included three special editions:

  • d’Elegance
  • Talisman
  • Cabriolet models.

Yet this was the final season for the mammoth Seventy-Five limousine and nine-passenger sedan. Led by Seville’s popularity, Cadillac set records for both sales and production.

Even though 1976 was a year of refinement rather than major body or engineering change at Cadillac, it signalled the end of several eras. GM’s last convertible was in its final season. This would be the final year for the low-rung Calais (after a dozen years in the lineup), and for the traditional mammoth Cadillac. Full-size Cadillacs retained the same ample dimensions as in 1975, but the new international-size Seville (introduced in mid-year) was 27 in. shorter, 8 in. narrower and a thousand pounds lighter than a Sedan DeVille. New grilles on all models carried on the traditional Cadillac crosshatch theme, though with a tinier pattern than in 1975 (actually crosshatching within crosshatching). Cornering lamps on Calais, DeVille, Brougham, nine-passenger and limo got new horizontal chrome trim, while taillamps gained a new bold look. Standard wheel discs kept the three-dimensional Cadillac crest on the hub (except Eldorado).

Cadillac’s ten models came in four size categories:

  • Family: Calais & DeVille
  • Personal: Eldorado
  • International: Seville
  • Executive: Fleetwood Brougham and Seventy-Five

Full-size Caddies stretched as long in wheelbase as 133 inches and 233.7 in. overall (limos, 151.5 and 252.2 in. respectively). They still carried a monstrous 500 cu. in. V-8. The smaller Seville, however, actually cost more than bigger Cadillacs. It was powered by a more reasonably sized 350 cu. in. V-8 with electronic fuel injection. (Fuel injection was optional in all models except the Fleetwood Seventy-Five.)

Eight different color accent stripes were available, and seven convertible top colors for the Eldorado. Vinyl roofs now were integral padded Elk Grain material except on Seville and Seventy-Five, which had cross-grain padded vinyl. Interiors were essentially the same as in 1975 with rosewood grain trim, plus bright wreath/crest and script plaques. New trims for full-size models include sporty plaids, plush velours, knits, and distinctive genuine leathers. Calais and DeVille coupes had a new vinyl roof, whose top molding served as continuation of the door “belt” molding.

All full-size Caddies except Eldorado included a Controlled (limited-slip) Differential for extra traction. All had lamp monitors atop each front fender to show status of front and rear lights. All could have optional illuminated entry and theft-deterrent systems. The new Freedom battery never needed water. All but Eldorado offered new-look turbine-vaned and wire wheel covers. A new option locked doors when the lever was shifted to “Drive.” Cadillac also offered Track Master, a computerized skid-control system that automatically pumped the back brakes in an emergency situation to shorten stopping distance.

Of special note on the option list was the Air Cushion Restraint System, announced for all models except Eldorado convertible and Fleetwood 75. This was a forerunner of the air bags that received so much publicity a few years later. Another option was the Astroroof, introduced in 1975, with sliding sunshade that permitted use as a electrically-operated sunroof or a transparent closed skylight. Both it and the “ordinary” sunroof panels could give safety along with an open-air feeling, now that the convertible was about to disappear.

Three full-size special editions with new refinements were offered this year: d’Elegance, Talisman and Cabriolet. New options included a pushbutton Weather Band (exclusive to Cadillac) built into the AM/FM stereo signal-seeking radio; loose-pillow style seats for d’Elegance packages; plus power passenger and manual driver seatback recliners for 50/50 front seats.

This year beat the all-time record (set in 1973) for sales and production, with 309,139 Cadillacs built. Seville was the shining star of the sales rise. After a brief 1975 model run, production zoomed upward for full-year 1976. At $13.000, Seville was the most costly standard domestic production car built by the Big Four automakers. It also offered a foretaste of what was coming soon as GM downsized all its models. Most Cadillacs, including all Sevilles and Eldorados, were built in Detroit; but 42,570 vehicles emerged from the Linden, New Jersey plant.

Full-size “standard” Cadillacs continued to sell well, defying the market conditions of the mid-1970s. Exactly 14,000 Eldorado convertibles were built in their final season (compared to just 8,950 in 1975). Cadillac promoted them as the “Last of a magnificent breed,” The actual “last” American convertible was driven off the line at Cadillac’s Clark Avenue plant in Detroit on April 21, 1976, by general manager Edward C. Kennard and manufacturing manager Bud Brawner. Passengers for this major media event included several production workers and Detroit mayor Coleman Young. Just 60 years before, the first Caddy to use the name “convertible” had appeared. For the past five years, Eldorado had been the only luxury American convertible; and for 1976, the sole survivor of the breed.

Reasons cited for the loss of ragtop popularity included

  • widespread use of air conditioners
  • high-speed cruising
  • sunroofs and vinyl roofs
  • improved audio qualities of stereo radio/tape systems, which couldn’t be appreciated fully in an open vehicle.

Actually, Cadillac produced 200 identical “final” convertibles, dubbed “Bicentennial Cadillacs” by Mr. Kennard. The one and only last example was kept for the company’s collection. All 200 were white with white top, white wheel covers, and white leather upholstery with red piping, dash and carpeting. A dash plaque confirmed the fact that it was one of the last–at least until the ragtop mysteriously re-emerged once again in the early ’80s. Speculation sent prices way UP. Their original $11,049 sticker price meant little as some “collectors” quickly began to snap up open Eldos at prices approaching $20.000. But before too long, prices fell almost as swiftly.

Convertibles never really disappeared. Within months various conversion manufacturers were slicing metal roofs off Caddy coupes to create custom convertibles. But the next regular production ragtop would be Chrysler’s LeBaron in 1982. In most recent years, over 2,000 Fleetwood commercial chassis had been produced annually, for conversion to hearses and ambulances. Most of those conversions were done by three companies: Superior, Miller-Meteor, or Hess & Eisenhardt. In addition, stretch limousines were built on Cadillac chassis by Moloney (in Illinois) and Wisco (in Michigan), among other specialty firms.
