Police vehicles in the United States and Canada are made by several maufacturers and are available in three broad vehicle types:
The first police car was a wagon run by electricity fielded on the streets of Akron, Ohio in 1899. Since the 1920s, the New York City Police Department has employed a fleet of Radio Motor Patrol vehicles to aid in its fight against crime within the city.
Ford's introduction of the flathead V-8 in its Model 18 in 1932––the first low-priced, mass-marketed car with a V8 engine––proved quite popular amongst police departments and led to strong brand loyalty. In turn, this gave the company a market-capturing edge that lasted until 1968. In the 1940s and 1950s, the "Big Three" (Ford, General Motors, and Chrysler) began to offer specialized police packages with severe duty parts. Foremost amongst these was the Ford package of 1950, which utilized the larger and more powerful Mercury engine in the smaller, lighter Ford. This ended the practice of some state police buying larger and more powerful, but higher-priced models including Buicks, Hudsons, and Chryslers. In 1969, Plymouth took first place in the police market, with Chrysler's 440 cu. in. V8s, Torqueflite transmissions, and torsion bar suspensions giving them a compelling advantage. Chrysler held this lead until the 1970s energy crisis drove buyers to smaller cars, and Chrysler subsequently discontinued their rear-drive platform after the 1989 model year.
