It’s a 2007 Police Tahoe, which is apparently the first SUV that was designed to be a law-enforcement machine. Many of the features that make it a good police truck are part of what make the new GMT900 SUVs good vehicles anyway, but it still features its share of specific elements for the boys in blue.
They include a lowered, stiffened suspension, an upfit-ready electrical system, high-capacity radiator, oil cooler, heavy duty brakes with ABS, a skid plate package, tire pressure monitoring system, long-life spark plugs, and an upgraded battery (or two). Power comes from the E85-capable 5.3L Vortec V8 with 320 horsepower.
