A glimpse of the article: Pursuit-rated enhancements Both the PPV and SSV models are powered by the Tahoe’s 5.3L V-8 engine paired with a 10-speed automatic transmission. To meet the most demanding needs of law enforcement, the PPV engine borrows high-performance 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. Engine oil and transmission fluid are cooled by dedicated, heavy-duty cooling systems specific for law enforcement applications. To handle the dynamic load of police pursuits, Chevrolet 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 unique 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.
