2015 GMC Sierra 3500 Overview
What’s New for the 2015 GMC Sierra 3500
The 2015 GMC Sierra 3500 gets an improved interior, a new double cab body style, and improved payload and towing capacities.
2015 GMC Sierra 3500 Exterior
The heavy-duty full size Sierra 3500 is a bold and capable truck featuring a new squared front-end design that takes in more cool air from outside the engine compartment than previous designs. The new double-cab model with conventional front-hinged doors replaces the former extended cab version. The pick-up offers 6.5 and eight-foot bed lengths, though regular bed models are only available with the long bed.
GMC’s attention to detail means features like projector headlamps, LED signature front lighting, chrome grille surround, wheel arch moldings, and an innovative cargo box do not go unnoticed.
2015 GMC Sierra 3500 Performance
The Sierra 3500 carries over last year’s engine selection, offering a standard 6.0-liter V8 that puts out 360 hp and 380 lb-ft of torque or the optional more powerful turbocharged 6.6-liter diesel V8 that makes 397 hp and 765 lb-ft of torque.
If you’ll be putting this beauty to work, you’re in luck. Offering a payload capacity of almost 7,400 pounds, a towing capacity of 19,600 pounds with the factory hitch (up to 23,200 pounds with a fifth-wheel setup), and available single- or dual-rear wheel configurations, the Sierra 3500 is built to get the job done.
2015 GMC Sierra 3500 Efficiency
Trucks in this segment are not rated for fuel efficiency by the EPA, and actual mileage will vary based on truck configuration, type of driving, and load (if any) being hauled.
2015 GMC Sierra 3500 Interior
The Sierra 3500 raises the bar for truck interiors. Featuring high-quality, soft touch materials, impressive craftsmanship, and all the latest technology, the Sierra 3500 offers comfort, convenience, and refinement.
The truck’s new inlaid door design, triple door seals, and hydraulic powertrain and body mounts mean a quieter interior, while larger touchscreens, hands-free phone functions, and a new six-gauge instrument cluster are practical and keep the driver connected and in control.
2015 GMC Sierra 3500 Safety
The 2015 GMC Sierra 3500 features an array of new safety technology including the available forward collision alert, a driver seat with vibrating alert, lane departure warning, and front and rear parking assist.
The Sierra 3500 also features OnStar, making this a safe pick-up truck both while you’re on the job and with the family.
