What was the most popular car in 1940s?

There's no single definitive answer to what the *most* popular car of the 1940s was, as different metrics (unit sales, registrations, etc.) and different parts of the decade would yield different results. Plus, wartime production significantly impacted car availability and variety.

However, the Ford V8 consistently ranked very highly in sales throughout much of the decade, often topping the charts, and is generally considered a strong contender for the title of most popular car of the 1940s in the United States. Chevrolet also had strong sales figures, often competing closely with Ford.
