It’s got a Cop Motor, Cop Tires, Cop suspension, Cop Shocks. Is This the New Tahoe PPV or What? by Evan Williams May 12, 2020 Share Comments Chevrolet is getting the all-new 2021 Tahoe ready for duty and that means more than just moving lots of people to the mall and soccer practice. It also means they’ve developed two new police models, the Police Pursuit Vehicle and the Special Service Vehicle. “Tahoe is the most aspirational vehicle in the law enforcement industry,” said Ed Peper, U.S. vice president, GM Fleet. And while it’s strange to have aspirations when it comes to what cruiser you’re driving on patrol, we can’t deny that having the largest vehicle with one of the last V8s has a lot of appeal when you’re spending all day inside. However, we also know that Italian cops get Lamborghinis for special missions and Alfo Giulia QVs for regular patrol. Let’s call it the most aspirational in the States. The PPV and SSV versions both get the Tahoe’s 5.3L V8 and 10-speed automatic, but the PPV gets some changes to make it more pursuit-ready. Like taking valve covers from the Camaro ZL1’s LT4 to improve crankcase ventilation and let it handle hard turns better than the old one. There are also heavy-duty fluid coolers for the engine oil and transmission fluid. New on the PPV are 20-inch wheels with special Firestone Firehawk Pursuit tires, Chevrolet track-tested them and worked with tire company engineers. The tires help cut 62 to 0 mph braking distances by 11 feet. The PPV gets unique suspension tuning and dampers as well as stabilizer bars and coil springs that reduce roll. And give “more driver confidence when executing police-type maneuvers.” Which we assume means grabbing donuts. Or hopping curbs. It has a lower ride height and bigger brakes with 16-inch rotors and Brembo six-piston calipers. A clutch-type limited-slip rear offers more traction under acceleration and the speedo is certified to 140 mph. Like the more civilian Tahoe, the PPV and SSV are bigger. 70.3 cubic feet of space behind the second row of seats is 18.3 more than the next-largest pursuit-rated SUV and the rear doors holes are 3.5-inches wider to make it easier to stuff perps in the back. It’s also plenty wide for officers with loads of kit on their belts, as well as laptops and other necessary gear. On the outside, this one uses the Z71 as a design starting point, meaning a more rugged front grille, a front skidplate, and better approach angles. The usual suite of safety gadgets is optional here, as is the rear-camera mirror that makes it easier to see around back-seat passengers, gear, and dog kennels. Push-button start and keyless entry are now standard. PPV models can be had in two or four-wheel drive, and the SSV is 4×4 only. SSV models are designed for off-road and towing rather than high-speed pursuit. Chevy doesn’t mention them getting the big brakes and tires, but SSVs can be had with a package to let them tow up to 8,200 lbs. Both have plenty of upfitter-ready wiring, like 112 wiring harness circuits that can be used for lights, sirens, and other electrical gear. They can even task steering-wheel buttons to engage the lights, sirens, or talk on the radio. Availability of the cop Tahoes should start early next year. So get ready to memorize a new set of headlights in your rear-view mirror.
