2015 Sierra 2500HD Overview

The GMC Sierra HD rolls into the 2015 model year looking like a new truck: The 2015 GMC Sierra HD gets new sheetmetal, a new cab, and interior and infotainment systems that debuted on the light-duty 2014 Sierra 1500.A Sierra Double Cab with four conventional doors replaces last year's extended cab, and all are roomier.What's underneath isn't necessarily new, but evolutionary updating or proven components.

GMC Sierra HD heavy-duty pickups are well suited to real-world use and abuse.They can haul tons of brick and cement and tow the concrete pump, then turn around to be used for a night on the town or grocery shopping while the fifth-wheel's left in camp or the horses are in the corral.If your hauling is lighter and happens once or twice a year or you tow a bass boat or ski boat, then the 1500-series may be better suited.If your load is heavy, however, or you do a lot of towing, the Sierra HD is the ticket, especially with the diesel engine.We found it towed a 5000-pound trailer load like it wasn't there and a 15,000-pound trailer with ease.

The luxurious Denali model is available in both 2500 and 3500 models.The 2015 GMC Sierra HD Denali comes standard with heated and cooled front seats, leather-wrapped heated steering wheel and a reconfigurable instrument panel, among other things.Denali is GM's response to Ford's King Ranch or Platinum and Ram's Lariat Longhorn.And Denali gives the GM HD owner a unique choice Chevrolet doesn't offer.

The 2015 GMC Sierra HD is built on the same chassis as the 2015 Chevrolet Silverado HD and shares all sheetmetal with it.Different hood trim, lights, grille, wheels, ruby red badges and red cabin illumination highlights (rather than aqua) distinguish the GMC from the Chevrolet.

For 2015, Sierra HD adds more standard equipment, like a locking tailgate, cruise control integrated diesel exhaust braking, electronic stability control and trailer sway control across the line.Updated infotainment systems will be available fall 2014 to turn your truck into a Wi-Fi hotspot.Additionally, Sierra HD carries GMC's Pro Grade Protection that covers scheduled maintenance (including diesel exhaust fluid, oil changes and tire rotations) for 2 years or 24,000 miles.

As with all heavy-duty pickup lines, the 2015 Sierra HD offers plenty of configurations with three cab styles, two bed sizes, single or dual-rear wheels and 2WD or 4WD.A 6.0-liter gasoline V8 is standard, rated at 360 horsepower for all pickup bodies.Power ratings aren't as high as the competition's gasoline engines.It's also offered to run on CNG, dropping power ratings to 301 hp and 333 lb-ft.

The 6.6-liter turbodiesel with 765 pound-feet of torque (more than twice the gas engine's) is competitive with Ford's Super Duty at 400 hp and 800 lb-ft and Ram's 350-385 hp and 660-850 lb-ft.GM and Ford use 6-speed automatics in their trucks; Ram offers a choice of 6-speed automatic or 6-speed manual.

For the entry price you get a functional pickup with load-carrying ability, but for big towing expect to pay much more.Options can add up quickly, with the diesel engine …
