Chevrolet Silverado 1500HD reviews

2006 Chevrolet Silverado 1500HD Driving Impressions

The Chevy Silverado remains one of the best-driving full-size pickups, even when measured against its newer competition. It feels tight and quiet, with 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. 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).

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 on wet pavement. Steering is responsive and offers the right amount of feedback; 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.

The optional Ride Control Suspension 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 it's helpful to study power ratings, payload ratings, tow ratings, fuel-economy, pricing, and other data to choose the best engine for your needs. 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; it also meets Ultra Low Emissions Vehicle, or ULEV, standards. But the two most popular engines are small-block V8s. The 4.8-liter V8 (294 cubic inches), which GM calls the Vortec 4800, is popular in base models and delivers 295 pound-feet of torque. It 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. The 5.3-liter Vortec 5300 V8 (327 cubic inches) generates 335 pound-feet of torque, enough grunt for all but the most demanding applications. It's the engine we prefer. It only rates 10 horsepower more than the 4800, but offers a lot more torque, over a broader range of speed. The 5.3-liter'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 about the same.

All of these Vortec small-block V8s are based on the SB2 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 1500HD, 2500HD and 3500 models, delivers 360 pound-feet for pulling big, heavy trailers. An 8.1-liter V8 is available for heavy-duty models, as well as a 6.6-liter Duramax t
