U.S. Automobile manufacturers halted their assembly lines by February of 1942 and would not resume automobile production until peacetime resumed. The assembly lines did not remain idle for very long, as all factories were converted to manufacture war material, with most making aircraft parts or guns. Cadillac factories produced engines for tanks with the first M5 tank being delivered to the Army in April 1942 and was powered by two Cadillac V-8s with Hydra-Matic transmission, with one driving each tank. During the war, Cadillac built six types of tanks and gun carriers, and roughly 12,000 fighting vehicles were assembled by the time hostilities came to a close in 1945.
After the war, Cadillac resumed the production of passenger cars advertised as 'battle powered' with 'victory' engines. Having produced engines during the war, Cadillac had an advantage when automobile manufacturing was allowed to resume. The first 1946 Cadillac model, completed on October 17th of 1945, was one of the earliest offered by GM since the end of the war. The 1946 Cadillac engines were the same 346 cubic-inch displacement as the pre-war powerplants and rated at the same 150 horsepower. Many internal parts, including the Hydra-Matic transmission, had been re-engineered for great reliability and strength as a result of the wartime experience.
The 1946 models were carry-over models from the pre-war 1942s. The 1947s were introduced that January and were only mildly freshened versions of the 1946s, costing about $200 more than the previous year's models. Additional brightwork, trim changes, and updates to the grille made the 1947 models distinguishable from the previous year. In the front, the 'egg-crate' grille had one fewer horizontal bar, and the parking lights became small, round units unless optional fog lamps were ordered. The 1946 rear fender shields were rubber, while the 1947 models were made of stainless steel. Another noticeable feature included the large, optional 'sombrero' wheel covers. These quickly became popular with hot rodders and Cadillac owners, and they remained on the parts list into the 1950s.
In 1947, Hydra-Lectric window lifts became standard equipment on the Series 75 Fleetwoods and Series 62 Convertible, which was the only soft-top. Cadillac produced 6,755 convertibles in 1947 helping the company's total sales of 61,926 surpass Packard, making them the best-selling American luxury car that year by nearly 11,000 units.
