Driving Impressions
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.
