The first U.S.-produced postwar compact car was the 1950
Nash Rambler. It was built on a wheelbase, which was nonetheless still a large car by contemporary European standards.
The term "compact" was coined by a Nash executive as a euphemism for small cars with a wheelbase of or less. It established a new market segment and the U.S. automobile industry soon adopted the "compact" term.
Several competitors to the Nash Rambler arose from the ranks of America's other independent automakers, although none enjoyed the long-term success of the Rambler. Other early compact cars included the
Kaiser-Frazer Henry J (also re-badged as the
Allstate), the
Willys Aero and the
Hudson Jet.
In 1954, 64,500 cars sold in the U.S. were imports or small American cars, out of a total market of five million cars. Market research indicated that five percent of those surveyed said they would consider a small car, suggesting a potential market size of 275,000 cars.

Recession of 1958, the only exception to the sales decline was American Motors with its compact, economy-oriented Ramblers that saw high demand among cautious consumers.
By 1959, sales of small imported cars also increased to 14% of the U.S. passenger car market, as consumers turned to compact cars. By this time, smaller cars appealed to people with a college education and a higher income whose families were buying more than one car. Customers expected compact cars to provide improved fuel economy compared to full-sized cars while maintaining headroom, legroom, and plenty of trunk space.

1960s
During the 1960s, compacts were the smallest class of North American cars, but they had evolved into only slightly smaller versions of the 6-cylinder or V8-powered six-passenger sedan. They were much larger than compacts (and sometimes even mid-sizers) by European manufacturers, which were typically five-passenger four-cylinder engine cars.

, which was built on the Falcon chassis. At that time, there was a distinct difference in size between compact and full-size models. Early definitions of vehicle size class were based on wheelbase, with models under 111 inches as compact, 111 to 118 inches intermediate, and over 118 inches as full size, at least until EPA classes based on interior volume of the passenger and cargo compartments were introduced in the late 1970s.

s that included the AMC Gremlin, Chevrolet Vega, and Ford Pinto.
In 1973, the Energy Crisis started, which made small fuel-efficient cars more desirable, and the North American driver began exchanging their large cars for the smaller, imported compacts that cost less to fill up and were inexpensive to maintain.
The 1977 model year marked the beginning of a downsizing of all vehicles so that cars such as the AMC Concord and the Ford Fairmont that replaced the compacts were re-classified as mid-size, while cars inheriting the size of the Ford Pinto and Chevrolet Vega (such as the Ford Escort and Chevrolet Cavalier) became classified as compact cars. Even after the reclassification, mid-size American cars were still far larger than mid-size cars from other countries and were more similar in size to cars classified as "large cars" in Europe. It would not be until the 1980s that American cars were being downsized to truly international dimensions.

In the 1985 model year, compact cars classified by the EPA included Ford's Escort and Tempo as well as the Chevrolet Cavalier. For the 2019 model year, the best sellers were the Toyota Corolla and Honda Civic.

One of the first compact cars that met those requirements was the Toyota Publica with an air-cooled two-cylinder opposed engine, the Datsun 110 series, and the Mitsubishi 500. The Publica and the Mitsubishi 500 were essentially "kei cars" with engines larger than regulations permitted at the time, while the Datsun was an all-new vehicle.
