Chevrolet’s all-new Tahoe can now be
ordered either as a Police Pursuit Vehicle (PPV) or a Special Service Vehicle
(SSV) thanks to its two new law enforcement packages. The PPV variant is
designed for high speeds with the added comfort needed by an everyday patrol
car, while the SSV is more focused on off-road and towing. Both are powered by
the same 5.3-liter V8 engine, mated to a 10-speed automatic gearbox.
The PPV model’s engine uses the
high-performance rocker covers from the Camaro ZL1 LT4 engine, which improve
crankcase ventilation. Meanwhile, engine oil and transmission fluids are cooled
by a heavy-duty cooling system, specific for law enforcement applications.
In order to handle the dynamic loads of
police pursuits, Chevrolet worked with Bridgestone to develop a pursuit-rated
all-season tire, which is how the Firestone Firehawk Pursuit rubber came to be.
Mounted on 20-inch steel wheels, these tires were tested at multiple race
tracks, while also promoting the PPV’s improved stopping distance – reduced by 3.35 meters from 62 to 0 mph on dry surfaces (compared to the 2020
model).
Other features include the tuned
suspension with unique monotube dampers, coil springs and stabilizer bars (for
less body roll), a lower ride height for improved stability, a heavy duty
braking system with six-piston Brembo calipers at the front, a heavy duty
limited slip rear differential and a 140 mph (225 km/h) certified speedometer.
Law enforcement agencies can get the Tahoe
PPV in either two-wheel drive or four-wheel drive configuration. However, the
SSV is available exclusively with 4WD. These models also come with a Terrain
Mode, providing performance similar to 4WD Low without the need for a two-speed
transfer case. Also available is a Max Trailering Package with a max-tow rating
of 4.1 tons. This package includes an active, two-speed electronic
Autotrac transfer case.
All law enforcement-focused Tahoes feature
available 4G LTE Wi-Fi Hotspot, a standard HD Rear Vision Camera with Rear Park
Assist, and an available Rear Camera Mirror for a wide, less obstructed view
behind the vehicle. New to 2021 models is the standard keyless entry and
push-to-start ignition, which means that police officers can leave their keys
on their belts for simpler and quicker use. As for active safety, the Tahoe PPV
and SSV get Forward Collision Alert, Lane Keep Assist with Lane Departure
Warning, Automatic Emergency Braking, Front Pedestrian Braking and Following
Distance Indicator.
