GMC calls the 2017 Sierra 2500 Denali HD its “most powerful Duramax diesel ever.” And rightly so.
If you need a heavy-duty hauler with some serious towing capabilities, then this truck was built for you.
This year, the 2500 Denali HD is available with a 6.6 liter Duramax Diesel Engine mated to a six-speed Allison 1000 automatic transmission, boasting a powerful 445 horsepower and 910 lb. ft of torque and towing 18,100 pounds. Combined with 4-wheel drive, this new engine offers an awesome amount of power and a little extra security when towing on unpaved roads.
Some of the features that lend to its ability to control heavy-duty loads include Stabilitrak with Hill Start Assist, Trailer Sway Control and Traction Control and Digital Steering Assist.
GMC says it increased the horsepower from its previous model vehicle by 12 percent plus a 19 percent increase in torque. All this is made possible by the brand’s new air induction system, stronger cylinder block and heads, updated camshaft profile, and a new electronically controlled turbocharging system. The result: this heavy-duty truck can move 0.7 seconds faster than its predecessor, going from 0-60 mph in 7.1 seconds.
One thing those of here at Anthony Buick
noticed is that in its description, the American automaker didn’t mention how refined the 2500 Denali HD actually is. Kbb.com
called the new Sierra Denali “both pleasing to the eye and functional” as it “puts the driver’s needs first and foremost.”
Inside, this heavy-duty work truck offers luxury in a quiet and spacious design, with heated and ventilated leather front seats, a soft-touch instrument panel, aluminum trim accents, a large center console that allows space for hanging file folders and laptops, 8” customizable Driver Information Center, Bose sound system, OnStar 4G LTE and built-in Wi-Fi hotspot.
Stronger. Faster. Smoother. The 2017 GMC Sierra Denali 3500 HD takes the power the 2500 Denali model was equipped with up a notch. The available all-new 6.6 liter Duramax Diesel Engine puts out 445 horsepower and 910 lb. ft. like its twin sibling, except with an increased towing capacity of 23,100 pounds.
The only other difference is in the price. The 2500 Denali HD Duramax starts at around $55,500 while the 3500 comes in at $55,580.
