Cadillac 62 Models & History 1963


In overall terms, 1963 Cadillacs were essentially the same as the previous models. Exterior changes imparted a bolder and longer look. Hoods and deck lids were redesigned. The front fenders projected 4-5/8 inches farther forward than in 1962, while the tailfins were trimmed down somewhat to provide a lower profile. Body side sculpturing was entirely eliminated. The slightly V-shaped radiator grille was taller and now incorporated outer extensions that swept below the flush-to-fender dual headlamps. Smaller, circular front parking lights were mounted in these extensions. A total of 143 options—including bucket seats; wool, leather or nylon upholstery fabrics and wood veneer facings on dash, doors and seat backs—set an all-time record for interior appointment choices. Standard equipment for cars in the 62 Series (6200 models) included power brakes; power steering; automatic transmission: dual backup lamps; windshield washers; dual speed wipers; wheel discs; remote control outside rear view mirrors; lefthand vanity mirror; oil filter; five tubeless black tires; heater; defroster and cornering lights. Convertibles were equipped with additional features, also used on all 6300 models.


Motor serial numbers took the same form used in 1962, with the first pair of symbols changed to “63” to indicate the new model year.
Applicable codes were stamped in the same locations on the cars.
The alphabetical body identification code “C” was no longer used, since the short-deck Town Sedan was dropped from the 62 Series.
However, the short-deck 6300 model, called the Sedan DeVille Park Avenue, was retained and used the same “D” body identification symbol.
Rooflines on two-door hardtops were restyled, which brought a change in body style coding, but not in the alphabetical suffix.

  • Although neither engine displacement or output changed, the 1963 Cadillac V-8 was completely redesigned.
  • Quieter, smoother and more efficient, the new motor was one-inch lower, four inches narrower and 1-1/4 inches shorter than the 1962 V-8.
  • It was also some 82 pounds lighter, due to the use of aluminum accessory drives.
