The GMC Sierra 2500HD is a heavy-duty truck, so it's built for heavy-duty jobs. Its engine has more power than the Chevy Silverado’s and Ford F-250 Super Duty. That extra power allows you to tow more weight and haul heavier loads. The suspension is also more potent than the competition’s, which gives you better control when hauling heavy loads or driving over rough terrain.
Go ahead if you want to drive a truck for the money and not for the environment. But hybrid technology is an excellent choice if you want to feel good about how your vehicle will help save the planet. This system uses both electric and gas motors in conjunction with each other to maximize efficiency while minimizing emissions.
Get the power and performance of a heavy-duty truck with a 6.6L V8 engine. The engine’s 420 horsepower gives you plenty of strength to get through your toughest jobs, while its 460 pound-feet of torque provides excellent low-end torque for pulling power and responsiveness.
