The Chevrolet Silverado remains one of the best-driving
full-size pickups, even with the new competition. The Silverado
feels tight and quiet. There's little road noise or wind
noise. Those are benefits of its stiff frame, which minimizes
noise and vibration from the running gear. The rigid chassis
allows the suspension to soak up and manage bumps and ruts
and tar strips. The cab is stiffened by a magnesium beam
behind the instrument panel and a lateral steel beam between
the magnesium beam and the right side of the dash. This
additional stiffening is designed to eliminate squeaks and
rattles, and we haven't heard any.
The Chevy Silverado rides more smoothly than the
Dodge Ram and
Ford F150. We drove a Silverado 1500 2WD
LS Extended Cab that rode very smoothly. Its long, 143-inch
wheelbase contributed to the ride (and enhanced high-speed
stability). Models with Quadrasteer seem to have a rougher
ride, however. At low speeds, a Silverado 1500 LT with Quadrasteer
we tested tended to bounce annoyingly over a succession
of dips. Could it be that the stouter rear end that comes
with Quadrasteer causes a rougher ride? Silverado 2500 models
ride rougher than 1500 models, but offer a bigger towing
capacity (10,700 pounds).
The Silverado handles well on dry pavement, loose dirt,
deep dirt, and off road. It tracks straight at speed on
dry pavement and it's stable on wet pavement. It holds its
line when the rear wheels spin under acceleration, even
when coming out of a low-speed turn. Steering is responsive
and offers the right amount of feedback. We find the Silverado
more responsive to steering than the Dodge Ram; the Silverado
has better on-center feel (less slop in the center). There
is a dead spot in the center when cruising, however, which
Chevrolet says is designed to minimize steering corrections
on the highway. Rack-and-pinion steering is used on Silverado
1500 4x2s. Four-wheel-drive and heavy-duty models use recirculating-ball
steering.
Quadrasteer is no gimmick. It enhances low-speed maneuverability,
and is a must-have for owners who tow, though it's available
only on selected models (1500 Extended Cab short-box and
2500 Crew Cab models, the last time we checked). The Silverado
is a full-size truck in a compact world and Quadrasteer
helps address that fact. Four-wheel steering helps when
maneuvering through crowded parking-lots and public garages.
With Quadrasteer, you can make a U-
turn
in places that previously required backing up. A Silverado
that requires 47.3 feet to turn around in, needs just 37.4
feet with Quadrasteer. That's 10 feet, a huge difference.
Where turning around on a narrow street takes five steps
in a standard pickup, it's only three steps with Quadrasteer.
Changing direction is quicker, less annoying.
While Quadrasteer helps around town, it is truly
a must-have feature when towing trailers. Quadrasteer can
make you look like trailering pro. First, it greatly improves
control when backing up, eliminating much of that trial
and error that occurs when you're not towing trailers on
a regular basis. Second, Quadrasteer allows you to back
a trailer into spots where you could not physically do so
without it. Quadrasteer also increases towing capacity slightly
due to the heavy-duty componentry that supports it.
The optional Ride Control Suspension, available with
or without Quadrasteer, is designed to enhance control when
pulling a trailer. Press the Ride Control button when the
truck is empty and the system firms up the shock damping,
which reduces bouncing somewhat, although at the expense
of increased harshness. When towing, Ride Control helps
reduce the tendency of the truck to pogo as the trailer
goes over bumps. It can also be used for better suspension
control when driving off road.
Four different engines are available for Chevy's light-duty
pickups, so when choosing one it's helpful to study power
ratings, payload ratings, tow ratings, fuel-
economy
ratings, pricing, and other data. People talk about horsepower,
but torque ratings better reflect how the truck will perform.
The V6 model is best for light-duty work when price and
fuel economy are paramount.
The two most popular engines are the small-block V8s. The
4.8-liter V8 (294 cubic-inch) is popular in base models
and delivers 295 pounds-feet of torque. The 5.3-liter V8
(327 cubic-inch) is rated at 330 lbs.-ft., enough grunt
for all but the most demanding applications. The 4800 offers
plenty of power unless you're towing, hauling heavy loads,
or driving at altitude, but it could definitely use more
juice when trying to accelerate up hills.
We prefer the Vortec 5300. It only rates 10 horsepower
more than the 4800, but offers a lot more torque. The 5300's
fat torque curve is useful for light towing and hauling,
but also makes the Silverado more fun to drive when commuting
or out
and about. Fuel economy is the same. These small-block V8s
are based on GM's SB-2 architecture introduced on the
Corvette and extended to the
Camaro and
Firebird in 1999. Since 2003, they have featured Electronic Throttle
Control for more precise, consistent throttle operation;
new oxygen sensors offer improved reliability and reduced
emissions during warm-up. All of Chevy's Vortec engines
come with 100,000-mile platinum-tip spark plugs, sequential
fuel injection, and 150,000-mile anti-freeze. (Larger engines
are available for heavy-duty Silverados. The big Vortec
6000 6.0-liter V8, standard on 2500 and 3500 models, delivers
360 lbs.-ft. for pulling big, heavy trailers. An even beefier
8.1-liter V8 is available, as well as a 6.6-liter Duramax
diesel.)

A five-speed manual gearbox is standard in the base
truck, but most buyers opt for the excellent four-speed
automatic. The automatic features a Tow/Haul mode that reduces
the tendency of the transmission to hunt between third and
fourth gears in hilly terrain; when it does shift, it shifts
quicker and harder in Tow/Haul mode. This strategy reduces
heat buildup for improved reliability. We recommend opting
for the automatic unless you run a snow-plowing operation
or have a specific need for a manual. With all the advances
that have been made in automatics, most of the advantages
of a manual are now more imagined than real, even when driving
off road.
Silverado's frame is the stiffest, lightest, and strongest
truck frame General Motors has ever built. Introduced on
the 1999 models, its front frame rails are hydroformed,
a process that uses high-pressure hydraulics to shape large
and complex components that used to be fabricated from smaller
stampings. One big hydroformed part is far more rigid than
a bunch of pieces welded together. Tubular crossmembers
and roll-formed mid-rails increase rigidity even more. This
stiff structure enhances handling and ride quality immensely,
while improving
crashworthiness. The front suspension comprises aluminum
upper and lower control arms, with coil springs on two-wheel-drive
1500s. Torsion bars are used on all 4x4 models and 2500
models.
Silverado comes with good brakes, always useful but
even more important when trailering or hauling a heavy load.
This is welcome by anyone familiar with the brakes in older
Chevy pickups and full-size SUVs. The current models offer
vastly improved brake-pedal response and stopping performance.
Braking force on the current models begins only an inch
into the pedal travel. The four-wheel disc brakes are huge
and powerful and come standard with ABS. Dynamic Rear Proportioning
improves stability under heavy braking, whether the truck
is loaded or empty. Chevrolet promises excellent fade resistance,
with long pad life and good heat dissipation. We've worked
the brakes hard on the Silverado and have experienced no
fade.
For best ride quality and lowest load height, we prefer
2WD models. Four-wheel drive can be quite useful at times,
and occasionally it's absolutely necessary. Silverado's
AutoTrac 4WD system lets the driver press a button to shift
between 2WD (for best fuel economy) and 4WD. Select 4WD
High, and it functions as a
traditional
part-time system that delivers excellent traction off-road.
Press the button for 4WD Low for particularly rugged terrain.
Spinning wheels in the rain? Pressing the Auto4WD button
cures that problem. Auto4WD works very well. Step on the
gas in the wet and there's half a moment of wheelspin as
power is transferred to the front wheels and the Silverado
takes off. Auto4WD is the mode to be in when road conditions
are loose and fluctuating: icy roads, spotty snow, gravel
roads, even slick pavement. Auto4WD eliminates the binding
of the front and rear wheels that can occur with traditional
part-time 4WD in tight parking lot maneuvers, nice in the
winter. When the mud or snow get deep, when the going gets
rugged, switch to 4WD High. When it gets steep or truly
nasty, switch to 4WD Low.
