Chevrolet Silverado 2500HD

These trucks are much stiffer and ride less comfortably than the standard Silverado 1500 (1/2 ton). They are designed for hard work, with a 3/4-ton load capacity. The ride is bouncy but the available engines include a relatively refined, Isuzu-developed 6.6-liter turbodiesel V8 mated to a smooth six-speed automatic. A huge 8.1-liter V8 is also available. These trucks are intended for commercial use or heavy-duty towing.
