GMC isn’t finished with the new 2017 Sierra HD, quite the contrary. To back up the 445 hp and 910 lb-ft of torque from the new 6.6-liter L5P Duramax turbo-diesel V8Â engine, GMC felt the Sierra HD could use a little more brute. Enter the 2017 GMC Sierra HD All Terrain X.
The 2017 GMC Sierra HD All Terrain X marks the third use of the brand’s “X” trim, signifying off-road prowess and capability. The Sierra HD All Terrain X marks a factory-ready package for off-road, trail-ready enthusiasts paired with the immense capability of the new Duramax powerplant.
But, if diesel isn’t your thing, the 2017 GMC Sierra HD All Terrain X will also be offered with the 6.0-liter L96 V8 gas engine as well. No matter the engine choice, the All Terrain X brings plenty of off-the-beaten-path goodies including:
- 18-inch black-painted aluminum wheels
- LT275/65R18 Goodyear Duratrac MT-rated tires that feature an aggressive tread pattern
- A unique body-color grille surround with All Terrain insert
- Body-color door handles and bodyside moldings
- Black power-adjustable heated and power-folding trailering mirrors with integrated turn signals, LED rear guidance lamps and LED amber clearance lamps
- Black belt moldings, front bumper skidplate and B-pillars
- Four-inch black sport side steps
- Black sport bar (mounted in the bed) designed to support available GMC Accessories LED off-road driving lamps
All of these features stand alongside the Z71 suspension package and a standard Eaton automatic locking rear differential.
The 2017 Sierra HD All Terrain X doesn’t skimp on creature comforts, either. Front and rear park assist, heated steering wheel, eight-inch touchscreen, heated seats and wireless charging are just a few ways the All Terrain X will pamper while it plunges into the off road.
GMC did not provide availability or pricing at the time of the announcement, but we do know the gasoline engine will launch first, followed by the new Duramax turbo-diesel at a later date.

That is a dandy machine. Sure it’s got a dandy-ass price.
Nice! Love everything about it except the Headlamps/Fog lights. Still can’t figure out why they didn’t change these like they did on the 2016 1500. I had a 2014 1500 but the 2016 lights are WAY better… Add those and cooled seats and I’ll buy one.
Still priced way to high. I’m sure this pushing 70k easy.
