According to USA TODAY, the economic crisis and high gas prices have caused a growing number of law enforcement agencies across the country to exchange their gas guzzlers for more fuel-efficient cars.

The New York City Police Department has about 100 hybrid vehicles in its 5,800-vehicle fleet that includes Toyota Priuses as well as hybrid Honda Accords, GMC Yukons and Ford Escapes.

Seattle police now have 38 hybrids, including Toyota Highlanders, Ford Escapes and Toyota Priuses. Other agencies are following in their footsteps, including the St. Landry Parish Sheriff's Department in Louisiana and the Berks-Lehigh Regional Police Department in Pennsylvania.

The Ford Crown Victoria Police Interceptor still holds 80 percent of the law enforcement market. In an effort to keep this market, Ford plans to develop a car that offers better fuel economy. USA TODAY reports that Ford also has plans to update the Crown Victorias.
