The police often get access to potent engine combinations that aren’t offered on civilian versions but in this case, both the PPV and SSV models are powered by a 5.3-liter V8 engine mated to a 10-speed automatic transmission rather than the Tahoe’s available 6.2-liter V8. Performance specifications for police vehicles are rarely made public but in civilian guise, this V8 produces 355 horsepower. The smaller of the two V8s was likely chosen because it offers Dynamic Fuel Management, which can operate in up to 18 cylinder patterns on as few as two cylinders to save fuel.
But don’t think for a moment that the police Tahoe is stock though, as the cops always have a few goodies to help them chase down perps. The PPV model receives unique suspension tuning with monotube dampers, coil springs, and stabilizer bars to reduce body roll. It also gets a lower ride height for improved high-speed aerodynamics, heavy-duty brakes with Brembo six-piston calipers, a limited-slip rear differential, heavy-duty oil coolers, and high-performance rocker covers from the Chevrolet Camaro ZL1 LT4 engine to handle extra lateral forces. The PPV is offered with two-wheel-drive or four-wheel-drive configurations but the SSV is exclusively 4WD.
