Available in a variety of configurations, supremely capable and offering improved interior materials and features, the 2015 GMC Sierra 2500HD remains an excellent choice among heavy-duty pickup trucks.
Chiseled and aerodynamic new look; impressive hauling and towing capabilities; carries on predecessor's refined and quiet ride; strong diesel engine; solid build quality.
Expansive seating position might not be to everyone's taste; as with current model, transmission ratios may be spread too widely for optimal towing performance.
Redesigned for 2015, the GMC 2500HD offers an improved interior, a sharp new look and a new double-cab body style.
Riding a wave of praise for the redesigned Sierra light-duty pickup, GMC follows up with the 2015 Sierra 2500HD heavy-duty pickup truck. The same interior upgrades found in the base model migrate to the big workhorses, among them higher-quality upholstery and materials on the dash and door panels, larger touchscreens to control entertainment and hands-free phone functions, a new six-gauge instrument cluster and a quieter cabin.
The Sierra heavy-duty trucks share the same square-jawed exterior poise seen on their new light-duty counterpart, although a new sealed front-end design draws cooler intake air from outside the engine compartment rather than the hotter environment under the hood. A new double-cab model with conventional front-hinged doors replaces the former extended cab and joins regular and crew cab configurations. The new heavy-duty pickup also offers 6.5- and 8-foot bed lengths, although regular cab models are only available with the long bed.
Engine selection carries over from the current model, with a 6.0-liter V8 making 360 horsepower and 380 pound-feet of torque, paired with a six-speed automatic transmission. The optional turbocharged 6.6-liter diesel V8 makes 397 hp and 765 lb-ft of torque, sent through a beefier six-speed automatic with manual shift control.
The 2015 GMC Sierra 2500HD can haul up to 4,306 pounds and tow 14,500 pounds. GMC officials say they've also further refined available Sierra HD features like automatic grade braking, diesel exhaust braking and trailer sway control. Bumper corner steps and the EZ Lift and Lower tailgate make it easier to load and access cargo in the bed, while optional safety features include forward collision alert, lane departure warning, a driver seat with vibrating alert, and front and rear parking assist.
