Ford says the new car will be more fuel efficient and offer lower ownership costs to municipalities than the existing Crown Victoria law enforcement vehicles.

Though the Crown Victoria is popular among police departments, the large sedan is relatively inefficient, getting an EPA-estimated average of 19 mpg. Ford says it will unveil the details of the new car in the first quarter next year.

Ford says it sells about 45,000 police vehicles a year, about 75% of all police vehicles sold in the U.S.
