Oldsmobile 1940s

Oldsmobile 1940s

For the 1940 model, Oldsmobile was the first auto manufacturer to offer a fully automatic transmission, called the Hydramatic, which featured four forward speeds.

The last pre-war Oldsmobile rolled off the assembly line on February 5, 1942. During World War II, Oldsmobile produced numerous kinds of material for the war effort, including large-caliber guns and shells.

Production resumed on October 15, 1945 with a warmed-over 1942 model serving as the offering for 1946.

Oldsmobile once again was a pioneer when, for the 1949 model, they introduced their Rocket engine, which used an overhead valve V8 design rather than the flathead "straight-8" design which prevailed at the time. This engine produced far more power than the engines that were popular during that era, and found favor with hot-rodders and stock car racers. The basic design, with few minor changes, endured until Oldsmobile redesigned their V8 engines in the mid-1960s.
