Cadillac Eldorado Models & History 1971
The bigger V-8 of 1970 hinted that a bigger Eldo was on the way. But though the mostly new 1971 edition was 6.3 inches longer between wheel centers, it was just 0.6-inch longer overall and only some 75 pounds heavier. Even so, the more rounded styling made it look far bulkier than its crisply chiseled forebears, and most of the extra wheelbase went ahead of the firewall, not into the cockpit. All of which later moved Automobile Quarterly to lament that “there is absolutely no logical reason for owning [this] Eldorado…. In terms of efficiency it ranks somewhere near zero…. In terms of handling it is a barge compared with the very nice car it was six years ago. It also has the thirstiest engine in production.”
Year-to-year changes were too numerous to list here, but the 500 V-8 persisted through ’76 (with fuel injection optional from early 1975), after which a more responsible new 425 took over. Styling was freshened for ’75 with skinless rear wheels, a pronounced beltline dip, and rectangular quad headlights; four-wheel disc brakes were standardized for ’76. There were always plenty of interesting options, such as the coupe’s Custom Cabriolet roof (from 1972), fancy Custom Biarritz and two-tone Biarritz Classic packages (from late ’76), “Track Master” rear anti-lock brakes (1972), even a driver’s airbag (a few for ’74). Horsepower withered with progressively tightening emissions limits — drastically with the switch from SAE gross to more realistic net ratings beginning in 1973 — but usable performance wasn’t much affected. Prices went the other way, breaking the $10,000 barrier in ’75.
