The Ford line of cars was updated in 1937 with one major change — the introduction of an entry-level 136 cu in (2.23 L) V8 in addition to the popular 221 cu in (3.62 L) flathead V8. The model was a refresh of its predecessor, the Model 48 and was the company's main product. It was redesigned more thoroughly in 1941. At the start of production, it cost US$850. The Ford Line bore several model numbers during this period, each related to their respective HP numbers. In 1937, 85 HP cars were known as Model 78 while 60 HP cars were known as Model 74. This changed to Model 81A and 82A respectively in 1938, and Models 91A and 92A in 1939.

The Ford Model 48 was an update on Ford's V8-powered Model 40A, the company's main product. Introduced in 1935, the Model 48 was given a cosmetic refresh annually, begetting the 1937 Ford before being thoroughly redesigned for 1941. The 1935 Ford's combination of price, practicality, and looks vaulted the company ahead of rival Chevrolet for the sales crown that year, with 820,000 sold.
