Cadillac initially came up with their Series 61 due to the Great Depression which of course put downward pressure on prices. Price point, even to sell Cadillacs, was important. Some of the independent luxury automakers that didn’t have the resources of a company like GM simply went out of business.

The New Post War Cadillac Design

New post war Cadillac design was introduced with the 1948 model. Up until that point designs had their roots in the pre war models. The 1948 Cadillac came in a Sixty-One model and a Sixty-Two Model. Among other differences, the Sixty-One Series had less trim than the Sixty-Twos.

The new post war design was spearheaded by Frank Hershey, working under Harley Earl, who is credited for the first tail fins on a Cadillac, and the 1955 Thunderbird.

These automobiles considered some of the most elegant automobiles of that period with smooth flowing lines. The new design also sported a tail fin that housed the tail lights. These new tail fins were reportedly had their origins based on the P-38 military fighter airplane. Fins would become a trademark of Cadillacs for many years thereafter. The 48 model year will always be remembered as the year Cadillac came out with tail fins which hit it’s most extravagant design in the 1958 to 1960 period.

In 1949 the most significant engineering change involved the introduction of the new overhead valve 331 cubic inch V8 engine.

A major design change occurred in 1950. These changes included a longer rear deck, a lower and heavier look and a broken rear fender line. Also, 1950 saw the new one piece windshield. The 1951 model had a minor facelift from the previous year.

As mentioned above, the 1951 Cadillac Series 61 was the lower priced Cadillac. This model also had a shorter wheelbase than the Series 62. (122 inch vs.126 inch)

Cadillac had mixed results catering to middle class buyers. No doubt a strong effort was made to accomplish this but the Series 61 was discontinued in mid-year. The most popular seller in 1951 was Cadillac’s Series 62 four door sedan. The Cadillac Series 62 was available as a pillared coupe, convertible or Coupe de Ville.
