The GMC Sierra 1500 All-Terrain X is GM's Coolest Modern Truck
Before getting into my review of the GMC Sierra All Terrain X, I should clarify that this is not GM’s answer to the Ford F150 Raptor. The Raptor is a high performance pickup built from the ground up – unique in almost every way from the next nearest model. The Sierra All Terrain X is a premium off-road package applied to the Sierra SLT, so it is not as elaborate of a package as the Raptor, but it is also far less expensive.
In short, it isn’t fair to compare the GMC Sierra All Terrain X to the Ford F150 Raptor as they are two different types of trucks in two different price classes, but in terms of off-road packages from General Motors – the All-Terrain X makes the Sierra one of their most capable trucks and their best looking modern half ton pickup. From front to back, the All-Terrain X transforms the GMC Sierra into one great looking sport truck designed to succeed off-road and on the roughest unpaved roads possible.
Building the Sierra All-Terrain X
The GMC Sierra All Terrain X is actually a Sierra SLT 4WD Crew Cab with the optional All Terrain and All Terrain X packages.
The All-Terrain package adds the majority of the functional bits, including the Z71 Off-Road Suspension Package with Rancho monotube shocks, an underbody shield, a high capacity air cleaner, unique 18 inch wheels and an Eaton automatic locking rear differential. The All-Terrain package also adds body colored front and rear bumpers, body colored door handles and body moldings, black exterior mirrors, a package specific grille with body color trim, a spray on bedliner and All Terrain badges on the outside along with power, heated black leather seats with red accents, a Bose premium sound system and bright door sill plates.
The All-Terrain X package adds a performance exhaust system which lifts the output of the 5.3L EcoTec V8 to 365 horsepower, package-specific 18 inch black painted wheels wrapped in Goodyear DuraTrac off-road tires, high performance LED headlights, a black step bar, gloss black mirror caps, black beltline moldings and the All-Terrain X bed mounted “sport bar”.
When you take the base price of my GMC Sierra SLT base price of $47,270 and add in the All-Terrain package ($2,105), the All-Terrain X package ($4,315) and the destination charge of $1,195, you get an MSRP of $54,885.
Major Cool Factor
I opened this review by proclaiming that the GMC Sierra All-Terrain X is the coolest looking modern GM truck, and with the combination of the rugged off-road tires on package-specific black wheels, the heavily blacked-out exterior and the red-trimmed sport bar in the bed – which gives this Sierra a hardcore off-roading look – there is no question that this is the most dramatic exterior package from GM on one of their half ton trucks.
Really, this is just a Sierra 1500 with pretty much everything on the outside painted black, shy of the front skid plate where it wraps up around to the front bumper, the badges and the lights, but the sport bar reaching up out of the bed with the Sierra logo in bright red and accessory fog lights mounted over the cab gives this package a major “aftermarket” look.(More on the next page)
Aside from the blacked-out exterior trim, the outside of the Sierra All-Terrain X benefits from the same premium look as the rest of the upper-level Sierra trimlines, with projection headlights trimmed with LED signature lighting and chrome-trimmed LED taillights, so while this is GMC’s most substantial off-roading package – it still has the expected element of GMC luxury.
Finally, the integrated steps in the corner of the rear bumper make accessing the bed of the Sierra All-Terrain X easier and with the factory spray-in bedliner, you can toss things in the bed without worrying about leaving any scratches or scuffs.
I won’t mince words – the GMC Sierra All-Terrain X is, in my humble opinion, the best looking half ton truck General Motors has sold in the modern era of trucks. While the aesthetic portion of this package is relatively simple, the combination of the black trim with the sport bar and the wheel/tire combo make this the most aggressive factory-built GMC truck in terms of styling and it is that rugged look which has led me to fall in love with how this truck looks from every angle.
The GMC Sierra All-Terrain X is all business on the outside, but on the inside, it is a well-appointed luxury truck with dual-zone heater leather seats, leather wrapped bits on the dash and door panels, a heated and leather wrapped steering wheel and a leather-wrapped center armrest cover. All of the leather in the All-Terrain X is black, with a unique carbon fiber-look leather on the seat bolsters and red stitching on the dash, doors and seats.
