If you’re in Oxnard and researching your next truck or SUV, this guide breaks down what makes the AT4 lineup worth your attention.
What Makes the GMC AT4 Models Stand Apart
The GMC AT4 models are designed to give capable off-road performance wrapped in a premium package. Each AT4 variant in the lineup builds on its base trim with added ground clearance, all-terrain tires, and off-road-focused suspension tuning.
GMC AT4 features like red front recovery hooks, skid plates, and specialized drive modes are standard across the lineup. These aren’t cosmetic additions — they’re purpose-built enhancements that make a real difference when the road ends and the trail begins.
The 2026 Sierra EV AT4: Electric Meets Off-Road Ready
The Sierra EV AT4 is one of the most exciting entries in the 2026 GMC AT4 models lineup. This all-electric pickup truck comes standard with 2-motor e4WD, a GM-estimated range of up to 478 miles with the available Max Range Battery Pack, and 35-in diameter all-terrain tires with 2 in of additional ground clearance compared to the Elevation trim. It also hasa maximum towing capacity of 12,300 lbs when properly equipped.
Available GMC AT4 features on the Sierra EV AT4 include Super Cruise hands-free driver assistance technology with a three-year OnStar One plan, 16.8-in infotainment touchscreen and a 14-in Head-Up Display, and 4-Wheel Steer with CrabWalk. CrabWalk allows the truck to move diagonally at low speeds — a useful feature on tight trails and uneven surfaces.
Fast charging is also available, with 800V public DC Fast Charging capable of adding up to 120 miles in approximately 10 minutes with the Max Range Battery Pack.
Capability Features Across the AT4 Lineup
No matter which of the 2026 GMC AT4 models you choose, you’ll find a consistent focus on real-world performance. The AT4 lineup includes selectable drive modes that allow you to tailor the truck’s performance for specific conditions, whether you’re on a highway, in deep sand, or navigating rocky terrain.
The Sierra EV AT4 also benefits from a 2-motor e4WD system that delivers power to all four wheels simultaneously, automatically adjusting to changing conditions for added traction. This responsive power delivery is a key part of what makes the electric powertrain feel so capable on and off the road.
Other practical GMC AT4 features include the available MultiPro Midgate, which extends the cargo bed length to a class-leading 10-ft, 10-in, and the power-open eTrunk that provides lockable, weatherproof storage under the hood.
Technology and Interior Comfort in the AT4
The GMC AT4 models don’t ask you to trade comfort for capability. Inside the Sierra EV AT4, you’ll find a 16.8-in Premium GMC Infotainment System with Google built-in compatibility and voice-activated technology. The 11-in Driver Information Center lets you view high-resolution maps and customize key vehicle data at a glance.
A 14-in multicolor Head-Up Display on the AT4 projects important driving information directly onto the windshield, keeping your eyes on the road. Up to 14 available camera views help with tight parking and maneuvering, while OnStar technology adds remote commands, Automatic Crash Response, and in-vehicle apps.
The AT4 Premium Package adds even more convenience, including the MultiPro Midgate, Rear Camera Mirror, Bed View Camera, and ProGrade Trailering System, making it a smart choice for drivers who need a capable workhorse with polished tech.
Safety in the 2026 GMC AT4 Models
Safety is built into the foundation of the GMC AT4 models. The Sierra EV AT4 comes with over 16 standard safety and driver assistance features, including Intersection Automatic Emergency Braking and Side Bicyclist Alert. These systems work together to keep you aware of your surroundings whether you’re on a crowded street or a back road near Oxnard.
Available Super Cruise® hands-free driver assistance technology brings an added layer of confidence on long highway stretches, allowing you to go hands-free on a growing network of compatible roads.
