How Much Does a 2018 GMC Sierra 2500 Cost?

The GMC Sierra HD comes in a wide variety of trim levels and body styles. In addition to choosing an engine, drivers can pick between regular cab, extended cab and crew cab. Drivers can also choose from regular or long beds and 2-wheel drive or 4-wheel drive. There are base Sierra, SLE, SLT and Denali trim levels.

As for trim levels, the Sierra starts with a base model simply called the Sierra ($40,195) that actually comes pretty well-equipped. Standard features include 17-in steel wheels, 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-inch IntelliLink touchscreen that brings with it Bluetooth and Pandora. You have a choice of cloth or vinyl upholstery.

Available in option packages for the base Sierra are heated power outboard mirrors, remote keyless entry, remote locking tailgate, 110-volt power outlet, cargo-box lighting and trailering equipment.

Next up is the Sierra SLE ($47,890), 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 ($51,695), 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 auto-dimming rearview mirror.

To the SLT, you can add the All-Terrain HD package. Available only as a crew cab, it adds all-terrain tires, an off-road suspension, underbody protection, side steps, a spray-in bedliner, body-colored bumper trim, parking sensors and a heated steering wheel. The All-Terrain X HD package builds on that with special blacked-out trim, 18-in black wheels, upgraded off-road tires, power-folding tow mirrors and a sport bar over the bed that includes LED lights.

Then there is the popular, range-topping Sierra Denali trim ($59,190). It adds unique styling elements plus 20-in wheels, spray-on bedliner, 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 and high-tech safety gadgets that range from a forward-collision alert system to a lane-departure warning system that vibrates the driver's seat when the pickup drifts from its lane.
