5 things I learned driving the 2015 GMC Sierra Denali 2500 - RoadandTrack.com
This is what a $65,000 pickup truck looks like. Big-dollar, heavy-duty trucks are the norm now more than ever. GMC says that. one in four of the nearly 500,000 trucks sold in the US last year were HD models, and the company's products enjoy one of the highest transaction prices of. any truck on the road. like the Sierra Denali 2500. The new cab makes all the difference. The 2015 GMC Sierra Denali 2500 uses plenty of carryover bits. The frame, axles, optional 6. 6-liter turbo diesel Duramax engine, and Allison six-speed. That doesn't mean this is an old truck. cab from the all-new Sierra onto the HD bones. The engine, transmission, and axles are still plenty capable. Throw 10,000 lbs on the hitch, and the. truck has no trouble out-accelerating an equivalently laden F-250 up a six percent grade, all gear ratios being equal. Sierra 2500 can hustle 3020 lbs' worth of cargo in this configuration and pull up to 13,000 lbs using a conventional hitch. No one in their right mind should be dragging six and a half tons of weight behind their three-quarter ton. Throw a gooseneck or fifth wheel setup in the bed, and the figure swells to 17,300 lbs with the 3. 73 axle ratio, and 17,500 if you ditch the four-wheel. Source: www.roadandtrack.com
