Which Sierra 3500 is the Best?
We suspect anyone seriously considering the 2018 GMC Sierra 3500 HD over its Chevy cousin wants a little more and is willing to pay for it. In that spirit, we suggest swinging for the fences with the Sierra in Denali trim armed with the Duramax diesel. Not only will it give you bragging rights to the segment's highest diesel-horsepower rating, but you'll impress the daylights out of the gang at the country club.
The 2018 GMC Sierra 3500HD comes in a wide variety of trim levels, body styles and configurations. There are Regular, Extended and Crew Cabs, along with regular beds and long beds, gasoline and diesel engines and 2- and 4-wheel drive. Drivers can also choose between two rear wheels or four (a "dually"), depending on their desired payload capacity.
As for trim levels, the Sierra starts with a base model simply called the Sierra ($42,390) that actually comes pretty well-equipped. Standard features include 17-inch steel wheels, an automatic locking rear differential, xenon headlights, LED running/accent lights, power locks, manual windows, cruise control, a front beach seat, a tilt-only steering wheel, a backup camera, a USB port, an auxiliary audio jack and a 6-speaker sound system. Also standard is a 7-in IntelliLink touchscreen that brings with it Bluetooth and Pandora. There is the choice of cloth or vinyl upholstery.
Next up is the Sierra SLE ($49,090), which adds alloy wheels, rear privacy glass, full power accessories, keyless entry and a remote-locking tailgate, power windows, a leather-wrapped steering wheel, a CD player, HD Radio and an 8-in touchscreen.
Above the SLE is the upscale SLT ($54,190), which adds 18-in wheels, power-folding mirrors, heated 8-way power front seats, driver memory settings, power-adjustable pedals, a tilt-telescopic steering wheel, dual-zone automatic climate control and remote ignition.
To the SLT (4WD/Crew Cab/single rear wheel), you can add the All-Terrain HD package. Available only as a Crew Cab, it adds all-terrain tires, the "Z71" off-road suspension, underbody protection, side steps, a spray-on bedliner, body-color bumper trim, parking sensors and a heated steering wheel. The Z71 suspension can be ordered separately on the SLE and SLT, though again, not with dual rear wheels.
There's also the popular range-topping Sierra Denali trim ($59,190). Available only as a Crew Cab, it adds unique styling elements, including a new grille design, 20-in wheels, side steps, a power-sliding rear window, parking sensors, ventilated front seats, a heated steering wheel, a navigation system, wireless smartphone charging and a Bose sound system.
In terms of options, the Sierra 2500HD offers quite a few, including upper trim level features being available on lower trims. In addition to the Duramax turbodiesel engine, Sierra buyers can also opt for a heavy-duty trailer package, a snow plow prep package and high-tech safety features, including a forward-collision alert system and a lane-departure warning system that vibrates the driver's seat should you drift from your lane.
The 2018 Sierra 3500HD boasts standard side airbags, side-curtain airbags, a backup camera, traction control, stability control and trailer sway control. Optional safety features include front and rear park assist, forward-collision alert and a lane-departure warning system.
The 3500HD has not been crash-tested by the federal government's National Highway Traffic Safety Administration or the Insurance Institute for Highway Safety.
