The Ford Crown Victoria Police Interceptor is a four-door sedan that was widely used by law enforcement agencies in the United States, Canada, and other countries. Over 200,000 units were sold to police departments across the country, making it the most widely used law enforcement vehicle in the world. The Police Interceptor was based on the popular Ford Crown Victoria and was equipped with a range of police-specific features such as heavy-duty suspension and brakes, a revised cooling system, and armor-plated door panels. The Police Interceptor was replaced by Ford's Police Interceptor Utility in 2012.
