1931 Plymouth Model PA Sedan

Chrysler’s introduction of the affordable Plymouth line in July 1928, aimed at challenging Ford and Chevrolet, helped the company navigate the early 1930s Depression. Despite not being a revolutionary design, the four-cylinder Plymouth featured hydraulic braking, full-pressure lubrication, and aluminum pistons—innovations unmatched by rivals for a decade. The car’s instant success led Plymouth to become the third top-selling brand in the US auto industry by 1933, trailing only behind Ford.

In 1931, the 3.2-liter four-cylinder PA model was launched on May 1st and proved equally successful. Highlighted by its ‘Floating Power’ engine mountings, promising a smooth drive with minimal vibration, the PA shared a resemblance to DeSoto and Chrysler’s higher-end six-cylinder models.

This design appealed to budget-conscious customers unable to afford more expensive models. To cater to those with tighter budgets, Plymouth offered two ‘Thrift’ models, and there was also a smaller-bore export version. Chrysler’s overseas factories in the UK, Denmark, and Sweden assembled these vehicles from semi or completely knocked-down chassis.
