DeKalb County Police brass have ditched their Ford Crown Victorias for a more economical car.

The command staff is now driving Chevy Impalas.

“We moved our Crown Vics to patrol,” Major James Conroy said. “The Impalas are better on gas mileage and cheaper.”

This is the last year Ford is producing Crown Vics for police. In addition to Impalas, police are adding more For Taurus cars to the fleet.
