The 2014 model-year saw the rollout of redesigned Chevrolet Silverado and GMC Sierra light-duty pickups that featured improved power and performance, throwback styling and cushy interiors.

General Motors keeps the pickup parade going for the 2015-MY with all-new Silverado and Sierra 2500/3500 HD models, and their designers followed a similar plan to rebuild the bigger trucks.

The Silverado and Sierra HDs compete in a select division with the Ford F-250 Super Duty and the Ram 2500.

The new GM models are available in WT (for “work truck”), LT and LTZ trims in regular cab (WT and LT only), double cab and crew cab configurations with a choice of a 6-foot, 6-inch or 8-foot bed and rear- or four-wheel drive with single or dual rear tires. All told, fleet buyers will choose from one of more than 150 possible combinations.

The HD’s engines carry over from the prior model. The base 6.0-liter gasoline-powered V-8 delivers 360 horsepower (hp) at 380 pound-feet (lb.-ft.) of torque while the vastly more popular 6.6-liter Duramax turbodiesel boasts 397 hp at 765 lb.-ft.; both are mated to a six-speed automatic transmission.

Combining the diesel dually with four-wheel drive produces a maximum conventional towing capacity of 19,600 lbs.; the OEM says a fifth-wheel configuration can pull up to 23,200 lbs.

The exterior follows the path set by the aforementioned light-duty models. The sheet metal is unapologetically boxy and the double cab, which replaces the outgoing extended cab, features front hinges on all four doors. GM’s “CornerStep” rear-bumper carve-outs and “EZ” lift/lower tailgate carry over from the smaller trucks.

The beds feature several added tie-downs; bed payload capacity is rated at just over 7,300 lbs.

In the work truck segment, utilitarian cabins have gone the way of the dodo. The new Silverado and Sierra HDs hew closely to the trend with an array of creature comforts that would put some SUVs to shame.

An 8-inch infotainment display is among the standard accouterments, along with a six-gauge instrument cluster, high-quality upholstery and surface materials and a noticeably quieter cabin, to name a few.

The 2015 Chevrolet Silverado and GMC Sierra 2500/3500 are available now. Starting MSRPs range from $31,310 for the regular cab to $35,095 for the crew cab; upping the trim level and adding power and four-wheel drive will drive some price tags into the $50,000 range.
