The 2018 GMC Denali 3500HD comes as a mid-cycle refresh of a full-size pickup offering a choice of two engines, two automatic transmission, an updated exterior and more comfortable cabin.
Also, buyers get to choose from an array of models and configurations. In addition, the HD, or Heavy Duty lettering means the powerplant packs plenty of horsepower and the specifically designed architecture offers superior rigidity and stability.
Exterior and Interior
The 2018 GMC Denali 3500HD sits on 18-inch, or optional 20-inch, alloy wheels and features tall athletic lines and sharp departure angles. The novelties come in the shape of the new C-shaped LED headlight assembly and matching C-shaped rear taillights.
For 2018, the extended cab is now replaced by a new Double Cab, which features longer, front-hinged rear doors with restructured B-pillars.
The profile presents chiseled lines with chrome running boards alongside the flanks, in addition to chrome door trim and chrome-tipped towing mirrors. Round back, a chrome rear bumper and corporate badging are standard, while the side mirrors include backup lights. These are twin LED lights which illuminate the area between the front windows and the tailgate.
At first glance the 2018 3500HD looks basically the same as the standard model, but there are changes and they come in way of upgraded and more plush materials, restyled gauges and new door seal plates.
The cabin comes with standard 4G LTE connectivity with Wi-Fi tethering, plus GMC’s IntelliLink infotainment system featuring navigation, voice recognition, and Bluetooth connectivity. There are also available five USB ports, a 110-volt standard house receptacle, and at least three 12-volt plugs.
The updated infotainment software allows compatible smartphone users to connect their device to the GMC’s IntelliLink infotainment system.
The 2018 GMC Denali 3500HD comes equipped with a 6.6-liter, Duramax, turbodiesel V-8 pumping out 397 horses and 765 pound-feet of torque, and comes paired with the Allison 1000 six-speed transmission.
Optional across the entire HD lineup is a Duramax 6.6-liter, turbo-diesel engine that delivers a total of 397 horsepower and 765 pound-feet of torque.
Both are solid engines for towing and hauling, though we would recommend the beefy diesel option if you want a pickup to tow heavy loads on a daily basis. The maximum towing capacity climbs up to 23,200 pounds.
Four-wheel drive is standard and it comes with upgraded suspension thanks to twin-tube Rancho shocks and aluminum skid plated underneath the body of the 2018 GMC 3500HD.
