The New York Police Department is adding some muscle to its car fleet: the 2006 Dodge  Charger. The department plans to buy 15 police versions of the car for a pilot program that will begin this summer, officials said Thursday.

With so many flashy foreign cars on the road, speed matters, said Leonard Lesko, the  NYPD's director of fleet services.

In a recent analysis by Michigan State Police, Chargers equipped with a V-8 engine had  the quickest acceleration (6.52 seconds to 60 mph) and fastest lap time (150 mph) of any police vehicle tested.   

"The car that does 110 mph doesn't do it anymore," Lesko said.

The police highway unit will test drive 10 Chargers featuring V-8 engines, officials said. The rest will have V-6s and hit city streets in the five boroughs.

If they pass inspection, they could replace hundreds of squad cars in the NYPD's 3,000-vehicle patrol fleet, now dominated by Ford Crown Victorias and Chevrolet Impalas.

The price was being negotiated. A company Web site lists the civilian model's starting price at $22,995.
