GMC Sierra 2500HD Road Test

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. Our tested 2500 rode very stiffly but could haul a 2,200-pound payload. The diesel is punchy and not too noisy, and the Allison-made six-speed automatic is smooth. ESC is standard on some extended- and crew-cab models.
