Pros: Highly useful; highly practical; great towing and hauling capabilities
Cons: Poor fuel economy; spartan equipment
What's New: The Sierra HD Work Truck is carried over from 2012 with minimal changes.
The 2013 GMC Sierra HD is a full-size pickup with heavy-duty capabilities. That means it can tow larger equipment and haul heavier loads than a typical "light-duty" truck. Two versions are available: a base-level 2500 HD model and an even more capable 3500 HD variant.
The truck splits into four trim levels -- base-level Work Truck, mid-level SLE and SLT, and upscale Denali. This overview covers the Sierra HD Work Truck, aimed mainly at commercial shoppers looking to tow or haul heavy loads.
The Sierra 2500 HD Work Truck starts around $30,500 for a base model, while the 3500 HD, which boasts a larger payload, is just over $32,000. Both come with the same standard engine: a 360-horsepower 6.0-liter V8. For those with greater towing or hauling needs, a 397-hp 6.6-liter turbodiesel V8 is optional.
But while the trucks boast capable engines, they don't feature many gadgets. Sierra HD Work Truck models include only basic items such as crank windows, manual mirrors, air conditioning and cruise control. You have to pay extra for comforts such as a CD player, GM's OnStar system and even cloth upholstery, as the Sierra comes standard with vinyl.
Still, that's good news for drivers who don't need a lot of frills. Such shoppers can choose between three body styles -- regular cab, extended cab and 4-door Crew Cab. They can also add 4-wheel drive, which is optional on all GMC Sierra Work Truck models.
