    With the right modifications, an off-the-shelf American police car can be a hyper-efficient surveillance machine.

    The typical American cop car isn’t born – it’s slapped together. Traditionally, this involved taking a production vehicle, bolting on a reinforced bumper and adding some lights and a divider between the front and back seats.

    But as law enforcement agencies update their fl eets, the police car is evolving. The Ford Crown Victorias of the past half-century are losing ground to more powerful models such as the Dodge Charger. (Dodge was in fi nancial limbo at press time, but we’re not giving up on the Charger just yet.) And these cars are being outfi tted with gadgets that add extra eyes and ears to a policeman’s arsenal.

    Not all of this gear is on the road yet, but the trend is toward turning the police car into another node in an omnipresent network of surveillance sensors, capable of tracking even people who have done nothing to arouse suspicion. And this has US civil liberties groups worried.

    “These devices allow for the forensic reconstruction of much of your life,” says Lee Tien, an attorney for the Electronic Frontier Foundation. “The police could go back through GPS data and plate records and know when you visited a strip club or an Alcoholics Anonymous meeting, or which political rallies or gun shows you drove to.”

    But those who have used the new technology say it could help protect civil liberties. “When a licence plate camera looks at a plate, it’s not looking at gender, race or ethnicity,” says Sergeant Daniel Gomez, a member of a Los Angeles Police Department division that tests new technologies. “All it’s looking for are numbers.” Whether the next generation of police cruisers will be a breakthrough for investigators, a step toward a surveillance society or a little of both, the era of the crime-fi ghting cab is screeching to a halt. Here’s what cop cars of the future may look like.

    1 GPS cannon
    A StarChase compressed-air cannon behind the grille could eliminate high-speed pursuits. Officers target a suspect’s vehicle with the cannon’s laser, then fire an adhesive, cellphone-size GPS tracker from up to two car lengths away, enabling dispatchers to remotely monitor the route. The LAPD is conducting field tests.

    2 Earth-shaking sirens
    Distracted drivers and loud music can make it diffi cult for sirens to clear a path through traffi c. The intersection- sweeping twin 21 cm woofers of the Rumbler system deliver a deep, rolling growl that can be heard (and felt) up to 60 m away. The system is already deployed in Washington, DC, and New York City.

    3 V-shape Led lightbar
    The lightbar has evolved from a straight line of fl ashing lights to a wedge of low-power LEDs. The V-shape formation is easier to spot from odd angles, reducing the chance of a collision as the squad car burns through intersections.

    4 License-plate cameras
    The surveillance equivalent of a street cleaner: roof-mounted cameras that suck licence plate data from every car they pass (more than 8 000 per 10-hour shift). “It can take a brand-new offi cer and make him a stolen-vehicles expert,” the LAPD’s Gomez says. An onboard computer compares the plates with a database of outstanding warrants.

    5 Thermal-imaging cameras If a suspect is hiding under cover of night, roof-mounted thermal cameras cut through total darkness, giving offi cers the night-vision edge of a police helicopter pilot. Advanced systems can pan and tilt, covering a full 360 degrees around the vehicle.

    6 Belt-friendly seats
    Car seats aren’t made to accommodate bulky equipment belts. When Atlantabased Carbon Motors’ E7 cop car goes into production in 2012, it will come with specially shaped bucket seats that keep guns and gear from digging into officers’ midsections.
