GMC’s Off-Road Trim
GMC knows trucks. From light-duty to heavy-duty, or from mid-sized to Chassis trucks, there are few jobs that don’t deserve a GMC truck. The specialized knowledge at GMC allows the brand to grace the market with well-designed GMC trucks that not only look spectacular, but are up to nearly any challenge at the worksite, on the road, or off in the wilderness. The 2019 Sierra is a sweet spot in the truck world: it’s classified in the “light duty” segment but equipped with plenty of power that gives it enough capability to compete with the bigger trucks on the block. The AT4 edition, in particular, is coveted for its off-road capabilities. This premium truck has been carefully engineered to be everything an adventurous soul can want in a truck. From towing capacity to off-road designed elements, the AT4 is for the driver who can’t – and won’t – stay on the regular roads. Previously just a trim, the AT4 is morphing into a sub-brand of its own, based on its highly capable design, bold exterior, and reputation for all-around beast status. With a rugged facade and specialty interior, it’s easy to tell a Sierra AT4 from the rest of the trucks in the segment.
What’s Under the Hood
Available in crew cab or double cab, the 2019 GMC Sierra AT4 comes well-equipped with a standard 5.3L V8 engine, featuring Dynamic Fuel Management and an 8-speed automatic transmission. This combination offers 355 horsepower and 383 lb-ft of torque, with a fuel economy of 15 miles per gallon city and 20 miles per gallon highway. Drivers of the AT4 can step up to an optional 6.2L V8 engine, which offers 420 horsepower and 460 lb-ft of torque. This more powerful engine, which is paired with a 10-speed automatic transmission, has a fuel economy of 15 miles per gallon city and 19 miles per gallon highway. Both V8 engines include GMC’s new Dynamic Fuel Management system, which is designed to increase fuel economy, as well as automatic engine stop/start systems.
Four-wheel drive is standard on the AT4 to allow for off-road maneuverability. The AT4 also offers the Traction Select System, which allows drivers to choose from a variety of drive modes that adjust transmission shift points, throttle mapping, and more to accommodate a variety of terrain and weather conditions.
The AT4 Difference
The first thing any driver will notice about the 2019 GMC Sierra AT4 is its distinguished exterior appearance. The black grille with vertical red recovery hooks greets you from the front. Black side window frames and tinted black fog lamp casings add to the dark and mysterious visage of the AT4. In the rear, an integrated dual exhaust and AT4 red badging advise that this is not a vehicle to be reckoned with.
Then comes the good stuff. The Sierra AT4 has been factory suspension lifted an extra two inches for supreme ground clearance. While 4WD is standard, the AT4 is equipped with a two-speed transfer case to allow it to handle nearly every type of terrain. Features such as an Eaton G80 MLocker differential and off-road-tuned Rancho monotube shocks make running wild look easy.
The 2019 AT4 has also been specifically engineered for off-road duty. Features like Hill Descent Control and Traction Select help drivers keep things safe, with specially crafted skid plates to protect all of the mechanical assets. The 18-inch wheels feature all-terrain or mud terrain-rated Goodyear Wrangler Duratrac tires, or drivers can opt for the available 20-inch wheels for even more clearance.
Inside, the GMC AT4 is ready to rumble. This model has its own interior design, and the dark trim includes textured aluminum finishes. The leather Jet Black seating includes accents of Kalahari red, with embroidered AT4 badges on the headrests. All-weather floormats come standard, making this truck just as mud-ready inside as it is outside.
When it comes to storage, the AT4 doesn’t slack off, either. Since the road is about to get bumpy, GMC installed 10-liter storage spaces in the rear seat backs, perfect for keeping important things still even when the going gets rough. Under the second row seat, there’s a 24-liter storage space for larger items that should be contained during wild rides, as well. Dual glove boxes and a center console also keep personal items safely stowed at all times.
The cargo space ranges from 62.9 to 71.7 cubic feet, depending on cab size, with a durable roll-formed steel box. Twelve cargo tie-downs are rated at 500 pounds per corner. The bed is also equipped with rear and side task lighting and a 120-volt electrical outlet. CornerStep footwells in the rear bumper allow for easier loading and unloading of cargo, as well. When properly equipped, the AT4 can tow up to 9,400 pounds, as well, with a variety of trailering safety features to keep loads on the road. The ProGrade trailering program allows an app to help monitor trailer conditions inside and out, including brakes, tire pressure, and lighting systems.
The AT4 also includes a heads-up color safety display, which projects important vehicle information to the driver’s range of view to keep focus on the path ahead. An off-road inclinometer on the heads-up display helps drivers rate angles, as well as left-to-right tilt. The driver assistance features also include a rear camera mirror, Surround Vision, Lane Change Alert with Side Blind Zone Alert, Front Pedestrian Braking, and Low-Speed Forward Automatic Braking built in.
AT4 CarbonPro Edition
For those looking to elevate their off-road, light-duty truck experience to the next level, consider the AT4 CarbonPro Edition, offered in a slick Onyx Black paint color. This truck marks the first use in the industry of a carbon fiber composite truck bed. This elite bed is stronger, lighter, and more resistant to dents and dings than previous beds, making trucks equipped with CarbonPro able to take on nearly any type of cargo. It also features the world’s first MultiPro six function tailgate, a GMC-exclusive that allows drivers to use the tailgate as a table, steps, additional storage space, and more. The CarbonPro is also equipped with a MultiPro audio system by Kicker, a power sunroof, cat-back performance exhaust, 18-inch MT Blackwall Goodyear Wrangler DuraTrac tires, 15” diagonal heads-up display, and rear camera mirror.
For a light-duty truck, the 2019 GMC Sierra AT4 offers some very bold features. It’s two-inch taller stance allows it to navigate previously unexplored terrain, with off-road capable wheels and tires to cover a lot of ground. Features like Traction Select and surround vision help off-roaders gain a sense of the area, adding an element to safety to the adrenaline rush of running the course. The AT4 is just as happy helping out around the job site, though. With plenty of cargo room, storage throughout the cab, and towing capability up to 9,400 pounds, this is not a truck that needs to stay in the garage during the work week. Whether your truck is your office, or a means of transportation, the MultiPro tailgate and CarbonPro optional bed can assist with all of your heavy cargo needs. For those looking for a truck that’s equal parts “work” and “play,” the 2019 GMC Sierra AT4 might be the exact vehicle of choice, day in and day out.
