Third generation (1948–1953)
The first all-new postwar Cadillacs arrived in 1948, sporting tail fins inspired by the Lockheed P-38 fighter plane [6] on a Cadillac. Series 62 Cadillacs had a slightly shortened wheelbase, but the track width was increased by two inches, increasing interior room. However, updated drivetrains would have to wait another year and for the time being, the new Cadillacs were still powered by the same 346 CID flathead V8 used across the board since 1941, which delivered only fair performance (0-60 in 16 seconds with a top speed of 93 mph). Fuel mileage was an estimated 14 mpg highway, 10 mpg city with the Hydramatic transmission, which was rapidly becoming the norm — by 1949, only 10% of Cadillacs were ordered with the 3-speed manual gearbox. Series 62 production totaled 34,213 vehicles for the 1948 model year, accounting for 68% of Cadillac's volume. The 1948 models had been slow to get into production and did not arrive in showrooms until February 1948, consequently Cadillac produced only 50,599 total vehicles for the abbreviated model year.
The new Cadillac OHV V8 was the big news for 1949, with minor trim differences otherwise. This 331 cu in (5.4 L) engine produced 160 hp (119 kW) and weighed 200 pounds less than the old flathead V8 in addition to being shorter and lower. The 331 V8 could also handle higher compression levels to take advantage of improved, higher octane postwar gasoline formulations. The major difference between Series 61 and Series 62 models of similar body style was minor trim variations. The higher-priced series again had grooved, front fender stone shields and bright rocker panel moldings. Chevrons below the taillights were no longer seen. The convertible was an exclusive offering. A heater was optional.[7] Sales reached a record 55,643.
The Cadillac Series 62 Coupe de Ville was introduced late in the 1949 model year.[3][8] Along with the Buick Roadmaster Riviera, and the Oldsmobile 98 Holiday, it was among the first pillarless hardtop coupes ever produced.[3][8] At $3,496 ($0 in dollars ) it was only a dollar less than the Series 62 convertible, and like the convertible, it came with power windows standard. It was luxuriously trimmed, with leather upholstery and chrome 'bows' in the headliner to simulate the ribs of a convertible top.[3][8]
55,643 Series 62 Cadillacs were produced in 1949 out of a total volume of 92,554 vehicles.
For 1950, major styling changes were performed. The cars were lower and sleeker, with longer hoods, and one-piece windshields were fitted. Hydra Matic transmission was now standard. The Series 61 was again a short wheelbase model, having been reduced to 122 in (3099 mm). Sales set yet another record at 59,818.
Full-length chrome rocker panels set off the 1951 model, and the Coupe de Ville was now marked with noticeably-improved trim, including Coupe de Ville script on the rear roof pillar. Sales were 81,844, or a record of over 74% of all Cadillacs sold. Popular Mechanics reported about 12-MPG at 45 mph.[9]
In 1952, to commemorate the 50th anniversary of Cadillac, the V-shaped hood and deck emblems were done as gold castings. The Series 62 sedan was also characterized by a higher rear deck lid contour. This provided additional luggage space. Back up lights were now standard equipment and were incorporated in the taillights. The grille wraparound panels were redesigned once again having broad chrome trim below each headlight with side scoop styling and gold-colored winged emblem mounted in the center. At the rear all Cadillacs adopted a through the bumper dual exhaust system. Deck ornamentation took the form of a Cadillac crest over a broad golden "V". New standard features included self-winding clocks, improved direction signal indicators, glare proof mirrors, stannate treated pistons, and four barrel carburetion. Engine output for the 331 was up to 190 hp (142 kW). Sales fell to 70,255, but with the Series 61 out of the way, Series 62 sales accounted for a record 78% of all Cadillacs.
The 1953 Series 62 saw a redesigned grille with heavier integral bumper and bumper guards, the repositioning of parking lamps directly under the headlights, chrome "eyebrow" type headlamp doors, and one piece rear windows without division bars. Wheel discs were fashioned in an attractive new disced design. Series 62 bodystyles were identified by non louvered rear fenders, the use of thin bright metal underscores on the bottom rear of the cars only and the decoration of both hood and deck lid with Cadillac crests and V-shaped ornaments. The Club Coupe model disappeared. Two door Series 62 were now all hardtops (including the better equipped Coupe de Ville) or convertibles. Another familiar name appeared on 1953's Series 62. The top-of-the-line subseries Eldorado was one of three specialty convertibles produced in 1953 by General Motors, the other two being the Oldsmobile 98 Fiesta and the Buick Roadmaster Skylark. The Eldorado was a limited-edition luxury convertible, and would eventually become its own series. It featured a full assortment of deluxe accessories, including wire wheels, and introduced the wraparound windshield to Cadillac standard production. Sales set a new record at 85,446.
