Many 1941 Plymouth P11 sedans were ordered by the military, with the Army requiring olive drab paint and the Navy taking civilian paint. Modifications could include lighting, sirens, and oil filters. The car came with four doors and the standard Plymouth 201 cubic inch 6, with 87 horsepower and a three speed manual with low gear ratios. The rear doors were suicide doors, so named because if opened even slightly, the wind would catch them and blow them open. The P11 was widely used for many tasks, including VIP transport and behind the lines duty, in both Europe and the South Pacific. The Navy used it heavily to move flag officers around at naval bases. It was 16 feet long, 6 feet wide, and 6 feet high, with a full eight inches of ground clearance. Other car brands include Ford, Chevy, Jeep, Hover and many others. without these companies the war could've had a different out come.
President Roosevelt established the War Production Board on January 16, 1942. It superseded the Office of Production Management. The WPB regulated the industrial production and allocation of war materiel and fuel. That included coordinating heavy manufacturing, and the rationing of vital materials, such as metals, rubber, and oil. It also established wage and price controls.
All manufacturers ended their production of automobiles on February 22, 1942. The January 1942 production quota had been a little over 100,000 automobiles and light trucks. The units manufactured at the beginning of February would bring up the total number of vehicles in a newly established car stockpile to 520,000. These would be available during the duration of the war for rationed sales by auto dealers to purchasers deemed
During the war, the automobile and oil companies continued to advertise heavily to insure that the public did not forget their brand names. Companies also were proud to proclaim their patriotic role in war production, and their advertisements displayed the trucks, aircraft, and munitions that they were making to do their part in combat.
America's military needed millions of tires for jeeps, trucks, and other vehicles. Tires required rubber. Rubber was also used to produce tanks and planes. But when Japan invaded Southeast Asia, the United States was cut off from one of its chief sources of this critical raw product. America overcame its rubber shortage in several ways. Speed limits and gas rationing forced people to limit their driving. This reduced wear and tear on tires. A synthetic rubber industry was created. The public also carpooled and contributed rubber scrap for recycling.
