[1] The EPA definition of a subcompact is a passenger car with a combined interior and cargo volume of 85–99 cubic feet (2,410–2,800 L).
[9][10] The Volkswagen Beetle was marketed with advertising pointing out the car's unconventional features as strengths and to get buyers to "think small.
"[11] Prompted by the British government for exports, Ford was one of the first companies to try and sell inexpensive small cars in volume.
"[13] Due to the increasing popularity of small cars imported from Europe and Japan during the late 1960s, the American manufacturers began releasing competing locally-built models in the early 1970s.
The Monza with its GM variants Pontiac Sunbird, Buick Skyhawk, Oldsmobile Starfire, and the Mustang II continued until the end of the decade.
In 1977, the U.S. Environmental Protection Agency (EPA) began to use a new vehicle classification system, based on interior volume instead of exterior size.
Because of consumer demand for fuel-efficient cars during the mid- to late-2000s, sales of subcompact cars made them the fastest growing market category in the U.S.[27] In 2006, three major subcompact models were introduced to the market, the Toyota Yaris, Honda Fit, and Nissan Versa.
[30][31] However, low fuel prices and the added room in SUVs impacted subcompact sales negatively in the late 2010s.
During this period, industry executives and analysts said that the subcompact car market was returning to historical norms after an unusual period when manufacturers had expanded small car lineups in anticipation of rising demand fueled by rising fuel prices, which has since eased.
[35][34] Models that were no longer sold in the United States by the end of the decade include the Mazda 2 (discontinued after 2014), Scion xD (2016), Toyota Prius C (2017), Ford Fiesta (2019), Smart Fortwo (2019), Fiat 500 (2019), Toyota Yaris (2020), Honda Fit (2020), and Chevrolet Sonic (2020).
