ONE-TICKET BOOK REVIEW NEW Silverado Work Truck
The new 355 hp, 5.3L V8 has more horsepower and a much fl atter torque curve than the old 5.3L V8. It has enough performance for the typical police use of a pickup.
Driving Impressions T e Silverado 4x4 Crew Cab with the 355 hp, 5.3L V8 hit 60 mph in 9.0 seconds. In direct comparison, the Ford F-150 SSV 5.0L V8 does it in 7.4 seconds while the RAM 1500 SSV 5.7L V8 does it in 7.0 seconds. T e Silverado reached 98 mph in 21.0 sec- onds—the top speed of all 1WT and SSV pickups is limited to around 100 mph. T e handling from the Silverado 1WT is
All Silverado 1500 models have four-
wheel disc brakes and four-channel ABS. Importantly, the new trucks have larger, vented 13-inch front rotors and 13.6-inch rear rotors. On the 4x4 Silverado, Stabili- Trak (electronic stability control) uses selec- tive brake control and changes to the engine torque to match the speed of each wheel, as well as matching the torque across the front and rear axles. Trailer Sway Control works with Stabili- Trak to help control towed trailers. When
the system senses trailer sway, it brakes the truck and/or reduces engine torque until the trailer sway is minimized. If a trailer with electric brakes is in use, the system also uses those brakes to control trailer sway. Hill Start Assist is a system that automati-
cally engages when the truck is on a grade of 5 percent or greater. Especially helpful when pulling a trailer, the system holds the brakes for 1.5 seconds after the brake pedal is released, or until the accelerator pedal is pressed, to prevent rollback.
very diff erent from the RAM 1500 SSV and the Ford F-150 SSV. Driving down the road, the Silverado 1WT had a defi nite fl oat-and- bobble, a driving impression mentioned by a number of both truck-oriented and non- truck fellow offi cers. T is doesn’t seem to be the spring rate (stiff ness) of the front coils/ rear leafs since the Silverado had plenty of ride stiff ness (up and down bumps). Instead, the subtle body roll (left to right)
seemed to be not enough control from anti- sway stabilizer bars and shocks. T e initial steering turn-in for a corner or turn pro- duced signifi cant body roll, enough to make left-right-left evasive maneuvers and left- right emergency lane changes challenging. Once the suspension was set, the Silverado had excellent steady-state cornering. After spending two weeks in the Silverado

1WT, we have one recommendation for whatever turns out to be the Special Service Vehicle package—get some of the stiff er roll control components from the Max Traile- ring Package. T is package includes an even larger diameter stabilizer bar and revised shock tuning for increased dampening. Hopefully, the Silverado SSV will handle better than the Silverado 1WT and more like the Tahoe PPV. We put over 1,000 miles of country patrol
and calls for service on the Silverado 1WT. T e EPA Estimates for the Silverado 5.3L V8 4x4 are 16 mpg City / 22 mpg Highway. We averaged 16.7 mpg, which is exactly 2
mpg better than the SSV competition under exactly the same driving conditions. T e Active Fuel Management (cylinder deactivation) was indeed active. T e instru-
