Coming soon is a redesigned 2003 Silverado with much bolder styling.

Silverado LT drives like a luxury car and is supremely smooth and quiet. That smooth, quiet, unified feel is largely due to the stiff frame, which isolates the running gear for reduced noise and vibration. A cast magnesium beam behind the instrument panel and a lateral steel beam between the magnesium beam and the right side of the dash further reinforce the stiff body. Squeaks and rattles simply don't happen. This is one strong truck, and its chassis rigidity allows the suspension to soak up and manage bumps and ruts and tar strips so well that its overall ride behavior is near the luxury class. A long, 143-inch wheelbase improves the ride further and enhances high-speed stability.

The 1500HD crew cab model does not ride quite as smoothly. When the bed is empty there is some road vibration, but drivers used to driving pickups should find it well within acceptable bounds and throwing some weight in the bed or adding a canopy should smooth it out some.

A big four-spoke steering wheel connects to a rack-and-pinion steering gear on 1500 4x2s; other models have recirculating-ball steering. Even the rack-and-pinion system has a fairly wide dead spot in the center when cruising, which Chevrolet says is designed to minimize steering corrections on the highway. The steering feels a bit too light, but Silverado still tracks beautifully and handles well on pavement, loose dirt, deep dirt, and off road.

Although the 4.8-liter small-block V8 is more popular in base models, the up-market LT Extended Cab comes standard with the optional 5.3-liter (327 cubic-inch) engine, rated 285 horsepower and 325 foot-pounds of torque. That's enough grunt to smoke the rear tires at will. The fat torque curve is useful for light towing and hauling, but it's also a lot of fun for commuting and touring. We recommend the 5.3 over the smaller 4.8. The big 6.0-liter V8 that comes on the 1500HD delivers a ton of torque for pulling big, heavy trailers.

Braking hasn't been a traditional strong point for U.S.-built pickups, but here again the Silverado breaks from tradition. Its four-wheel disc brakes are huge and powerful and come standard with ABS. Braking force begins only an inch into the pedal travel. A new feature called 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 worked the brakes hard on our truck and experienced no fade. Anyone used to the brakes in the previous-generation Chevy pickups and full-size SUVs should be very pleased with the brake-pedal response and stopping performance. Chevy's heavy-duty Silverados offer excellent ride quality and lots of power with the capability of carrying big loads and pulling heavy trailers.

Whether 2WD or 4WD, the ride quality is nice. These trucks ride much smoother than GM's pre-2001 heavy-duty trucks and better than Ford's Super Duty trucks. Handling is surprisingly good for such a big truck. They can cover ground quickly, even on winding rural roads. A hydroformed front frame let GM's engineers to tune the suspension more precisely for a better ride and handling. Front suspensions use torsion bars for durability. The front axles are designed to take up to 4800 pounds, while the rear axles can handle up to 8600 pounds.

Four-wheel disc brakes have reduced stopping distances and give the driver a solid pedal feel, a huge improvement over GM's previous-generation trucks. Bigger front rotors, larger brake pads, improved linings offer better stopping power and longer pad life. Dynamic rear proportioning shortens stopping distances by transferring front and rear brake bias to the tires with the best grip.

The base engine is the Vortec 6000, a 6.0-liter V8 (366 cubic inches) that generates 300 horsepower and 360 foot-pounds of torque at 4000 rpm. Introduced for 1999, it's designed for a 200,000-mile operating life with 10,000-mile oil change intervals. Its aluminum cylinder head is similar to that of the L56 Corvette. It comes with a choice of a heavy-duty five-speed manual and GM's optional 4L80-E four-speed electronically controlled automatic, which features the Tow/Haul mode.

Want more power? The big Vortec 8100 V8 delivers 455 pounds-feet of peak torque at 3200 rpm. Torque is that force that propels the truck off the line and this 8.1-liter, 496 cubic-inch V8 has gobs of it. It generates 400 lbs.-ft. at just 1600 rpm. Don't expect neck-snapping acceleration, however. Quicker acceleration performance when towing is the objective. And it does this very well. Introduced last year, this 8.1-liter V8 replaces GM's 7.4-liter V8. It has advanced features such as an engine oil life monitor and a limp-home mode.

The new Duramax 6600 diesel is smooth, quiet, and powerful. It punches out an amazing 520 lbs.-ft. of torque at just 1800 rpm. GM's Duramax diesel engine is built in Moraine, Ohio, but was developed with Isuzu, one of the world's largest manufacturers of diesel engines. The new 6.6-liter Duramax offers improved fuel economy over the old 6.5-liter GM diesel it replaced. The Duramax was designed for a 200,000-mile operating life, according to GM engineers, and for easy serviceability. Half of heavy-duty truck pickups are sold with diesel engines.

The Duramax and Vortec 8100 offer a choice of a ZF six-speed manual or optional Allison 1000 five-speed automatic. Both have close-ratio gearing, which provides exceptional launch, hill climbing, and towing capability and economy. Their heavy-duty components are stronger than those typically found in one-ton truck transmissions, providing exceptional durability.

The ZF six-speed manual is easy to shift and is fully synchronized in all gears with dual-cone synchronizers in second and third. A convenient shift pattern allows the shift lever to be moved forward for reverse and straight back for first, making it easier to maneuver quickly in tight spaces. Second gear works well for taking off with a light load; first is a creeper gear.

As good as the six-speed manual is, the optional Allison five-speed automatic is one of the most impressive features of these trucks. We highly recommend it for its responsive performance. Available for the Vortec 8100 and Duramax engines, the Allison is designed to last 200,000 miles; GM engineers said it's ''over-designed,'' meaning it's heavier duty than it needs to be. But it's also sophisticated and keeps in close contact with the driver and the engine with full electronic control. It adjusts shifting according to driving style. The Tow/Haul mode keeps the transmission in gear longer to reduce hunting and heat buildup. This transmission senses when the truck is going downhill, senses when the driver is applying the brakes and downshifts, reducing wear on the brakes. This grade braking feature works great; just touch the brake pedal as the truck is going down a grade. On a practical side, the Allison transmission is set up to make it easier to attach power take-off (PTO) accessories. It downshifts crisply as the truck comes a stop. The Duramax and Allison combination does not come cheap, however.

GM says its heavy-duty pickups offer the highest GVWR for hauling and the highest GCVW for towing in the business. Payloads range from 3321 pounds for a 2500HD Crew Cab 4WD to 5753 pounds for a 3500 Regular Cab 2WD. Two-wheel-drive models and smaller cabs offer higher payloads.

Both the Vortec 8100 gas and Duramax 6600 diesel permit towing trailers up to 12,000 pounds. We pulled a 7000-pound trailer (a two-horse tandem-axle trailer full

Car-like drivability with traditional truck styling. Truckloads of payload and pulling power.

Like its exterior design, Silverado's interior reflects traditional Chevrolet thinking. The doors and door openings are the largest in the industry, and the cab is the roomiest.

The instrument package looks like a cross between a Corvette's and a traditional pickup's. It includes a large speedometer and tachometer flanked by four smaller gauges. All use pleasant, highly legible white-on-black graphics.

The sound-system control panel is located above the climate controls. The climate control system uses a rotary-dial layout that works perfectly. There are three 12-volt outlets at the bottom center of the dashboard for radar detectors, cellular telephones, laptop computers, and other accessories.

An LT Extended Cab we drove awhile back came with six-way power front bucket seats with seat heaters and memory. The doors lock automatically as soon as you pull away, a security feature that can be de-programmed at the dealership. The LT also comes with a lockable floor console large enough to hold a picnic lunch for a family of four; it comes with a reversible, removable cup holder tray and a storage nook in front of the lid. Air conditioning outlets and a set of drop-down cup holders are built in for rear-seat passengers. A compass is incorporated into the LT's overhead console, along with three storage areas for sunglasses, garage door opener, and small items. The door trim is a nice combination of vinyl panels and dotted velour that is soft and warm to the touch.

The back seat in the extended cab offers more room and comfort than we expected. When cargo capacity is more important than hauling passengers, the entire rear seat assembly can be removed with a wrench and lifted out through the door.

A more recent drive in a 1500 HD crew cab revealed a really comfortable truck. The back seats are roomy and comfortable, very similar to those in an uplevel Suburban. The seats were trimmed in handsome leather and they could be flipped down to provide a big, secure cargo area. This is a great truck for someone who wants a roomy rear seat with interior cargo space and big trailer-towing capability.

About the only thing we don't like about the Silverado interior is the design of the interior door handles, which swivel through an up-and-in arc, and felt loose whenever we used them. We'd prefer more resistance and a more positive feel.

OnStar, which is now standard on LT models, is a communications and location system that allows customers to call for 24-hour assistance. The system calls for assistance automatically if the truck's airbags have deployed. Standard seating is much better than basic. In fact, these trucks are downright comfortable. They are quite roomy, among the roomiest available. Four cab styles are available: Regular Cab, Extended Cab, Crew Cab, and Chassis Cab. All offer identical front-seat space. The extended-cab's rear-door openings are the largest in the industry, according to Chevrolet

The Crew Cab offers roomy rear seats, comfortable for two adults, capable of three. In addition to their people-carrying capability, the Crew Cab models come in handy in many sometimes unforeseen ways. We like changing into our driving suits in the back seats at races or putting on a pair of waders when fishing in cold weather. The rear seats fold down, a huge benefit for carrying cargo inside.

OnStar, the telematics system, comes standard on Silverado LT extended cab and Crew Cab models. OnStar when send someone to the rescue if your airbag deploys and you don't respond to their calls. All models come standard with dual front air bags with a passenger-side deactivation switch on regular and extended cab models to protect small occupants.

Chevrolet Silverado is overall the best among full-size pickups. Many buyers will prefer its more conservative design. Chevy's full-size Silverado pickups are among the smoothest, quietest, most civilized, best equipped, and most enjoyable trucks we've driven. Heavy-duty trucks have never been better than the Chevy Silverado. About one-third of all full-size pickup buyers opt for heavy-duty models, and they couldn't go wrong with the Silverado 2500 HD or 3500. These are great trucks.
