Chevrolet is offering the 2021 Tahoe in two law enforcement packages: the Tahoe Police Pursuit Vehicle “is designed for high speeds and dynamic capability with the added comfort needed from an everyday patrol vehicle; the Special Service Vehicle is more focused on off-road and towing needs where high-speed operations are not required”.
Both the PPV and SSV models are powered by the Tahoe’s 5.3L V8 gasoline engine paired with a 10-speed automatic transmission. However, the PPV engine borrows high-performance rocker covers from the Camaro ZL1 LT4 engine, which are claimed to improve crankcase ventilation, allowing the 2021 Tahoe to handle high lateral conditions better than its predecessor. In addition, the engine oil and transmission fluid are cooled by dedicated, heavy-duty cooling systems specific for law enforcement applications.
As for tires, Chevrolet has worked with Bridgestone to develop pursuit-rated all-season tires. The Firestone Firehawk Pursuit tires are shod with 20-inch steel wheels. Chevrolet said that the tires have been tested at multiple race tracks and play a large role in the PPV’s improved stopping distance, which has been reduced by 11 feet from 62 to 0 mph on dry surfaces compared to the 2020 model.
Other enhancements of the PPV include specific suspension tuning with unique monotube dampers, coil springs and stabilizer bars for less body roll and more driver confidence; lower ride height compared to civilian Tahoes for better high-speed aerodynamics and improved vehicle stability; heavy-duty braking system with large front Brembo 6-piston aluminum monoblock calipers on 16-inch rotors; clutch-type limited-slip rear differential; and speedometer certified at 140 mph (225 km/h).
While the Tahoe PPV is offered in two-wheel drive and four-wheel drive configurations, the SSV is exclusively 4WD. The 4WD models offer a Terrain Mode, which provides performance similar to 4WD Low without the need of a two-speed transfer case, Chevrolet said.
Special Service Vehicles also offer an available Max Trailering Package with a max-tow rating of 8,200 lbs (3,720 kg). This package includes an active, two-speed electronic Autotrac transfer case with push-button controls and an integrated trailer brake controller.
