The Complete History
The American Police Car
It begins with a battery-powered wagon in Ohio and ends, more or less, with a sport utility outrunning every sedan on a Michigan proving ground in 2019. In between, the American police car became the most specialised passenger vehicle in the country, and then stopped being a car at all.
This page is the whole arc in one place. Each section links to a longer treatment.
The wagon, and thirty years of losing
1899–1932
America’s first police vehicle was electric. The Akron, Ohio police department took delivery in 1899 of a battery-powered patrol wagon designed by city engineer Frank Loomis, built by a buggy company for $2,400. Two four-horsepower motors, 18 mph, about 30 miles between charges, and roughly 5,000 pounds. Its first job was collecting a drunk from the corner of Main and Exchange.
What follows is not a march toward modernisation. It is three decades in which American police were almost always driving slower cars than the people they chased. Cost was the brake: at $2,400 an electric wagon was beyond nearly every city budget, and it took the Ford Model T falling to around $440 before motorisation became general.
Then Prohibition made it worse. Liquor money bought speed, and a bootlegger in a modified Hudson or Cadillac could simply drive away from a patrol Buick. When Ford released the V8 in 1932, it finally gave police a fast car — and gave criminals exactly the same one, on the same terms, at the same price.

The package, and what it fixed
1950–1956
Before 1950 there was no such thing as a police car from a factory. Departments bought civilian sedans and modified them locally, and no two forces did it the same way. Ford changed that by putting the modifications on the assembly line with standard parts at a price on the order form.
The package was not about speed. It was about a specific engineering problem: a patrol car idles for hours powering a radio and lights, then runs flat out, then does it again tomorrow. So it specified the largest radiator available, heavy-duty fans, oil coolers, a heavy-duty charging system, stiffer springs, bigger brakes, and a calibrated speedometer that was a legal instrument rather than a convenience.
Chevrolet followed in 1955, Chrysler in 1956. The category existed.

The horsepower years
1955–1978
The 1955 Chrysler C-300 was the first American production car to make 300 horsepower, and it was sold to anybody with the money. That industrialised the speed problem: where moonshiners had built fast cars by hand, Detroit now sold them by the thousand.
What followed was the golden age of the American police car, and Chrysler dominated it. The peak is a 1969 Dodge Polara Pursuit with the 440 Magnum, which recorded 147 mph at Chrysler’s Chelsea Proving Grounds. No police sedan was recorded going faster for another thirty-seven years, until a Hemi Charger reached 150 mph at the Michigan test in 2006.
Two-door pursuit cars are a separate case, and a faster one. Michigan recorded the Chevrolet Camaro B4C at 155 mph in 1995, 159 in 1996, and 160 in 2000 — figures that sat in the same test books, in a category most people arguing about police car top speeds have never looked at.
The last stand came in 1978. A Plymouth Fury with the 440 recorded 132.7 mph at the Michigan State Police test, according to the surviving published figures, beating every other car in the field on top speed, acceleration and the road course — and submitting the lowest adjusted bid as well. Two of the six cars tested that year were disqualified outright for failing minimum acceleration standards.
After 1978 the big block was gone.

The collapse, and the strange rescue
1979–1993
Emissions rules, two fuel crises and downsizing took the American police car apart. The low point is documented precisely: the 1980 California-specification Dodge St. Regis topped out at 85 mph on flat ground and around 65 uphill. Officers called them dog cars. California sold eighty-six of them at cost, some without ever going on patrol.
It is worth being exact about that, because the collapse was narrower than it looks. In the same model year, the federal-specification St. Regis with the 360 engine recorded 122.7 mph at the Michigan test, and the Plymouth Gran Fury 360 recorded 124.6, the fastest full-size police car in America that year. Both General Motors entries were eliminated for failing minimum standards. The disaster was California’s, not Chrysler’s.
The rescue came from an unexpected direction. Unable to buy a fast sedan at any price, the California Highway Patrol abandoned the format entirely and in 1982 bought 406 Mustangs. Ford’s own advertisement claimed the car chased Porsches for a living. It was a specialist tool — tiny back seat, no room for equipment — but for a decade it was the fastest thing wearing a badge.

The last great sedans
1991–2011
Chevrolet dropped a Corvette-family V8 into the Caprice for 1994 and produced the first genuinely fast full-size police sedan in fifteen years. Then General Motors killed it after 1996, because the plant that built it was needed for trucks.
That left Ford alone. The Crown Victoria took roughly eighty percent of the American police sedan market and held it for over a decade — not by being fast, because Michigan recorded it at about 129 mph, well below the Caprice it outlived, but by being repairable, durable and available. It won by being the last one standing.
When Chrysler finally returned in 2006 with a Hemi-powered Charger, it recorded 150 mph at the Michigan test and beat the Polara’s thirty-seven-year-old figure, on the same proving ground where the record had been set.

The year it stopped being a car
2012–present
The sport utility had been in Michigan’s testing since 1995, sitting in the same table as the Camaro and the Crown Victoria and losing. By 1997 five of the eleven vehicles tested were sport utilities, and the following year Ford declined to let its Expedition and both Explorers run the road course at all, stating they were not designed or intended for pursuit. In 2006 the two-wheel-drive Tahoe entered the pursuit category proper, and recorded 124 mph — already faster than a Crown Victoria with the shorter axle ratio.
2012 is where it starts to turn. The Tahoe recorded 139 mph; the brand-new Ford Police Interceptor sedan, purpose-built to replace the Crown Victoria, recorded 130. The sport utility was faster than Ford’s replacement car, and it had more room, a higher seating position and all-wheel drive as well.
It was not yet faster than every car. In the same test a Chevrolet Caprice 9C1 with the 6.0 ran 154 mph, and three cars broke a nineteen-year-old braking record. The sedan still had an argument.
It lost it in 2019. That year the Ford Police Interceptor Utility with the 3.0 EcoBoost ran 150 mph, reached 60 in 5.77 seconds and 100 in 13.59, and lapped Grattan faster than every Charger in the field. Not roomier and nearly as quick — quickest, fastest, and roomier. There was no trade left to make.
The American police car did not die. It stopped being a car.

See the ebookFrequently asked questions
What was the first police car in America?
An electric patrol wagon delivered to the Akron, Ohio police department in 1899, designed by city engineer Frank Loomis and built by the Collins Buggy Company for $2,400. It managed 18 mph and about 30 miles per charge.
What was the first factory-built police car?
The 1950 Ford, with what Ford called its police package. Before it, departments bought civilian sedans and modified them locally. Chevrolet followed in 1955 and Chrysler in 1956.
What is the fastest police car ever built?
It depends what counts as a police car. The fastest sedan is the 1969 Dodge Polara Pursuit with the 440 Magnum, which recorded 147 mph at Chrysler’s Chelsea Proving Grounds and was not beaten until a Hemi-powered Charger reached 150 mph in 2006.
The fastest police vehicle of any kind in the Michigan record is the Chevrolet Camaro B4C, recorded at 160 mph in 2000, with 159 in 1995–96, 1999 and 2002. It was a two-door pursuit car rather than a general patrol vehicle, which is why it rarely appears in the argument — but it is in the same test books.
The Camaro’s figures repeat almost exactly across several years, which is consistent with an electronic limit rather than the car’s true maximum. Michigan never marked them as limited.
Why did American police cars get slower in the 1970s?
Emissions regulations forced compression ratios down and added equipment, two fuel crises made large engines a budget liability, and downsizing shrank the cars. Chrysler’s 440 lost nearly a hundred horsepower in three years, and after 1978 the big block was gone from police work entirely.
When did SUVs replace police sedans?
In two stages. In 2012 the Chevrolet Tahoe PPV recorded 139 mph against 130 for the brand-new Ford Police Interceptor sedan — but a Caprice 9C1 ran 154 mph in the same test, so the sedan was not beaten outright.
That happened in 2019, when the Ford Police Interceptor Utility with the 3.0 EcoBoost was the quickest and fastest vehicle in the entire test at 150 mph. By 2025 Michigan tested no police sedan of any kind, for the first time in the programme’s history.
