2018 GMC Denali 3500HD Review And Mpg

The 2018 GMC Denali 3500HD comes as a range-topping refresh of a Heavy Duty full-size pickup offering efficient engines, upgraded automatic transmission, in addition to an updated exterior and comfortable cabin. Just like the last time, consumers can choose from a whole host of models and configurations. On top of that, the new architecture offers impressive rigidity and stability.

Exterior and Interior


The 2018 GMC Denali 3500HD comes with bespoke 18-inch, or optional 20-inch, alloy wheels and cuts an impressive figure with its tall athletic lines and few overhangs. The updates come in the shape of the revised LED headlamps and the complementing rear taillights. Also, the extended cab is now replaced by a new Double Cab, offering front-hinged rear doors with restyled B-pillars.

The chiseled profile features bold lines with chrome finish on the running boards, as well as the chrome door trims and chrome-tipped towing mirrors. Around back, the sculpted rear bumper and corporate badging are standard, while the side mirrors come with the always useful backup lights, including twin LED lights which illuminate the area between the front windows and the tailgate.

The new 3500HD doesn’t differ much from the outgoing model, but there are still slight changes and they come in the shape of upscale materials in the cabin, as well as restyled gauges and brand-new door seal plates.

What’s more, the cabin comes with the 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 new infotainment software allows compatible smartphone users to connect their device to the GMC’s IntelliLink infotainment system.

Powertrain

The 2018 GMC Denali 3500HD still features the same 6.6-liter, Duramax, turbodiesel V-8 pumping out 397 horses and 765 pound-feet of torque, carried from the outgoing model. The diesel unit is coupled to the Allison 1000 six-speed transmission. Optionally, you can choose a 6.2 liter V-8 with 420 horsepower and 450 pound-feet of torque.

Both are efficient engines for towing and hauling, though we would recommend the beefy diesel option if you need a pickup for towing heavy loads on a daily basis. The maximum towing capacity goes up to 23,200 pounds. Four-wheel drive is standard regardless of the trim.
