Recently freshened, the HD Sierras are designed for heavy towing and hauling, not ride comfort and handling. The 2500 and 3500 HD models are offered in two- and four-wheel drive as well as with the dual rear-wheel setup. Multiple bed sizes are offered. The standard engine is a 6.0-liter V8. We tested the 2007 2500 with 365-hp, 6.6-liter turbodiesel, which produced 660 foot-pounds of torque.
