Who needs 660 pound-feet of torque? Someone who needs to drag 13,000 pounds around, that's who. And the only 3/4-ton truck that can tackle that job is Chevy's Silverado 2500 HD, armed with the optional 6.6-liter Duramax diesel V-8
Chevrolet's heavy-duty truck, introduced as a 2007 model, changes little for the 2008 model year. It shares some essential pieces with GMC's Sierra heavy-duty trucks, along with some mechanicals from the big GM SUVs (Tahoe, Suburban,Yukon, and Escalade).
The Silverado heavy-duty trucks are offered in 3/4-ton and one-ton versions, the 2500HD and 3500HD. Three cab styles, three cargo box styles and five wheelbase lengths are offered, so the Silverado can be ordered to fit specific jobs - like towing up to 16,700 pounds, which GM says is best in the heavy-duty class.
This year's changes include standard XM satellite radio, available power driver seat on regular-cab Silverado HDs, and revamped gauges. Two new red paints are offered, and Duallie models get 17-inch wheels, up from 16-inchers offered last year.
