Chevrolet announces new police Tahoes for 2021
The 2021 Chevrolet Tahoe is available 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 V-8 engine paired with a 10-speed automatic transmission. The PPV engine borrows rocker covers from the Chevrolet Camaro ZL1 LT4 engine. These rocker covers improve crankcase ventilation, allowing the 2021 Tahoe to handle high lateral conditions better than its predecessor, according to the company. Engine oil and transmission fluid are cooled by dedicated, heavy-duty cooling systems specific for law enforcement applications.
To handle the load of police pursuits, Chevrolet notes it worked with Bridgestone to develop a pursuit-rated all-season tire. The Firestone Firehawk Pursuit tires, mounted to 20-inch steel wheels, were tested by Chevrolet 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.
Additional performance enhancements of the PPV include:
- Specific suspension tuning with monotube dampers, coil springs and stabilizer bars for less body roll and more driver confidence when executing police-type maneuvers.
- Lower ride height compared to civilian Tahoes for better high-speed aerodynamics and improved vehicle stability.
- Heavy-duty braking system with large front Brembo six-piston aluminum monoblock calipers on 16-inch rotors.
- Heavy-duty, clutch-type limited slip rear differential.
- Speedometer certified at 140 mph.
Tahoes have been serving law enforcement since 1997 when the first Pursuit-Rated Package was introduced.
The company says the 2021 Tahoe Police Pursuit Vehicle and the Special Service Vehicle will be assembled at General Motors’ Arlington Assembly in Texas with globally-sourced parts in late 2020 with availability beginning early 2021.
