Cadillac's 75th anniversary year arrived with a shock to traditionalists, as full-size models endured an
eye-opening downsizing. "You must drive it," the ads declared, "to see why we call it the next generation of the
luxury car." The new C-bodied DeVille, Brougham and limousine were 8 to 12 in. shorter, 3-1/2 in. narrower,
and an average of 950 pounds lighter than their massive predecessors. Still, many models managed to keep the
same leg room in front and rear (or even more). Only Eldorado carried on in its mammoth form a while longer,
and Seville had entered life in 1975 with contemporary dimensions. Even the commercial chassis shrunk, from
157.5 down to 144.5 inches in wheelbase, requiring funeral car and ambulance suppliers to create some new
All models except Seville carried a new lighter, smaller 425 cu. in. (7.0-liter) V-8 engine. That powerplant
emerged as the result of testing 110 experimental engines. The huge 500 V-8 was gone. Electronic fuel injection
was optional in DeVille, Brougham, and Eldorado. Standard Turbo Hydra-matic fed power to low-ratio drive
axles. Four-wheel disc brakes were standard on Seville, Eldorado and Brougham. Astroroofs and sunroofs were
again available. Carryover special editions included Coupe and Sedan DeVille d'Elegance and Brougham
One new special edition joined the lineup: the Eldorado Custom Biarritz. All sedans now had piliars and framed
door glass. (The 'true' four-door hardtop was gone for good.) With Calais departed, DeVille took over as the
cheapest Caddy (base price under $10,000). Dash gauges could be pulled out from the front for servicing. All
models had a new two-spoke steering wheel -- but those were wide spokes. A new door design offered better
hold-open qualities. Anti-corrosion treatment on all models included zinc-rich primers, hot melt sealers, wax
coating, Plastisol-R-, and deadeners. Cadillac also expanded the use of Zincrometal-R- and bi-metal (stainless
steel on aluminum), corrosion-resistant inner front fender panels, and elimination of areas that trapped dirt and
water. Wheels and tires were now match-mounted for smoothest ride.
For 1977, there were five models:
- DeVille (two-door coupe and four-door sedan),
- Fleetwood Brougham (four-door sedan),
- Fleetwood Limousine (four-door sedan, four-door formal limousine, and commercial chassis used in hearses
and ambulances, etc.),
- Eldorado (two-door hardtop coupe),
- Seville (four-door sedan)
- All Cadillacs again had a 13-symbol Vehicle Identification Number (VIN) on
the forward lower edge of the windshield frame, visible through the windshield.
- The first digit ("6") identifies the Cadillac Division.
- The second symbol denotes car line/series:
- "S" Seville
- "D" DeVille
- "B" Fleetwood Brougham
- "F" Fleetwood limousine
- "L" Eldorado
- "Z" commercial chassis.
- Digits three and four indicate body type:
- "23" 4-door limousine with auxiliary seat
- "33" 4-door formal limousine with partition window
- "47" 2-door coupe
- "69" 4-door piliared sedan
- "90" commercial chassis (number identifies name of body builder)
- Next comes the engine code:
- "R" V8-350 EFI
- "S" V8-425 4 Bbl.
- "T" V8-425 EFI
- Symbol six indicates model year ("7" 1977).
- Seventh is an assembly plant code:
- "Q" Detroit
- "E" Linden, NJ
- At the end is a six-digit sequence number:
- running from 100001 to 400000 for C-bodies and Eldos built in Detroit
- running from 450001 to 550000 for Sevilles from Detroit
- running from 600001 to 690000 for C-bodies built in Linden
- A nine-digit derivative of the VIN appears on the engine.
- A Body Number Plate has codes for model year, model number, trim combination, body number (assembly
plant and sequence built), paint color(s), and a number-letter code that shows the date built.
- That plate is mounted on the upper left cowl between hood rear seal and windshield except Eldorado, on left
side of cowl next to hood rear bumper; and Seville,riveted to cowl above evaporator case.
- Introduced: September 23, 1976.
- Model year production (U.S.): 358,487 for a 3.9 percent share of the industry total.
- Calendar year production (U.S.): 369,254.
- Calendar year sales by U.S. dealers: 335,785 for a 3.7 percent market share.
- Model year sales by U.S. dealers: 328,129.
- Cadillac executives didn't appreciate Ford's advertising claim that an LTD was now as good as a Cadillac.
- But the new smaller Caddies were selling well, at least at the beginning.
- Sales of 328,129 units scored 9.5 percent over the 1976 record.
- Model year production also beat the 1976 score, by 16 percent.
- Rumors early in the year suggested that Cadillacs might be "upsized" within a couple of years; but that didn't
seem likely in view of the need to meet stricter Corporate Average Fuel Economy (CAFE) requirements.
- Now that the Fleetwood Seventy-Five was gone, conversion companies stepped up production of "stretch"
- Moloney Coachbuilders (in Illinois) offered a 40-inch stretch of Brougham for under $15,000 (plus the cost
of the car, of course).
- Phaeton Coach Corp. of Dallas, and the California-based American Custom Coach-works did similar work.
- The latter also created custom convertibles based on the Coupe DeVille chassis, while an Ohio firm
(Convertibles, Inc.) turned out ragtop Eldorado conversions.
