Long gone are the days when a heavy-duty work truck meant a vinyl bench seat, two-speaker radio and manual everything. The Sierra 2500HD Denali is the Cadillac of pickup trucks, with a feature laden, leather-lined interior and upgraded exterior trim differentiating it from its more humble Sierra 2500HD stablemate.
The 2500HD Denali comes standard with a gas-powered V8, while a turbodiesel eight-cylinder is optional. The gas-burning 6.0 V8 puts out 360 horsepower and 380 lb-ft of torque, while the mighty diesel displaces 6.6 liters and makes a staggering 397 horsepower and 765 lb-ft of twist at a usefully low 1,600 rpm. Both engines put their power to the ground via 6-speed automatic transmissions, though the diesel uses a heavy-duty Allison unit.
Maximum payload and towing capacity are 3193 and 16,800 pounds, respectively.
The 2500HD Denali is available with a 78.8-in. standard bed or a 97.7-in. long bed, but comes only as a four door extended cab. Rear- or four-wheel drive is available.
Outside, the 2500HD Denali distinguishes itself with a four bar chrome grille with round air inlets, body-color bumpers, chrome door handles, chrome accents and standard 17-inch (or optional 18- and 20-inch) polished forged aluminum wheels.
Leather seats with 12-way power adjustment, brushed aluminum trim and power adjustable pedals make the interior a comfortable place to relax on the way home from the construction site, although on average the grade of interior plastics is disappointing for the price. For the latest model year, heated and cooled seats and a leather wrapped, heated steering wheel are standard, as is a rear-view camera that makes parking the big rig a bit easier.
Significant options include a touch-screen navigation system bundled with a 7 speaker Bose audio system and an off road package with skid plates and beefy shock absorbers.
Safety features include dual front and side airbags, while head curtain side-impact airbags are available as an option.
Key Competitors
In this class, only the Ford F-250 King Ranch can compete with the level of luxury offered by the Sierra 2500HD Denali. While the leviathan Ford ultimately has higher towing and payload capacities, the GMC’s slightly smaller size and curb weight can make it a more user-friendly truck in all but the most intense work situations.
The slightly less luxurious Ram 2500 with the Laramie Longhorn trim level could also be considered a rival.
