Cardinale GMC – Why the 2026 GMC Sierra EV AT4 Fits Weekend Trails and Weekday Duty for Watsonville, CA Drivers
The 2026 GMC Sierra EV AT4 earns its reputation as the electric truck that thrives when the route turns off the map — and then settles into an easy rhythm for the Monday commute. With a 2-motor e4WD system and a GM-estimated range up to 390 miles, AT4 blends the confidence of immediate torque with the refinement expected from the GMC badge. Rugged hardware like 2 inches of additional ground clearance, red front recovery hooks, and 35-inch all-terrain tires pairs with advanced tech — 4-Wheel Steer with CrabWalk®, Terrain mode, and a Head-Up Display — to help you place the truck precisely on narrow fire roads or crowded job sites.
Inside, the Forest Storm interior delivers a premium, dark-accented look that stands up to work boots and still feels right for a night out. Super Cruise® with a 3-year OnStar® One Super Cruise plan is included, helping enable hands-free driving on compatible roads for supported trailering confidence. Add the available MultiPro™ Midgate for extra cargo length, a panoramic fixed glass roof for an airier cabin, and Energy Transfer Pro with up to 10.2 kW of off-boarding power to run job-site tools or power campsite gear. AT4 proves that going electric does not mean compromising capability — it means elevating control, visibility, and everyday ergonomics.
- Trail agility: 4-Wheel Steer with CrabWalk® helps the truck move diagonally at low speeds to finesse tight turns.
- Everyday comfort: The Head-Up Display and premium seating reduce fatigue on longer commutes.
- Charging confidence: DC fast charging capability supports quick range recovery on road trips.
- Cargo flexibility: MultiPro™ Midgate expands bed length to carry longer items cleanly and securely.
- Power on site: Energy Transfer Pro delivers up to 10.2 kW for tools, tailgates, and emergencies.
How do you choose between AT4 and other Sierra EV trims? If you value ride height, tire footprint, and enhanced maneuverability as much as advanced driver assistance, AT4 is the sweet spot. The chassis tuning, tire spec, and drive modes are tailored for mixed terrain, while standard Super Cruise® and a premium cabin ensure the truck never feels like a compromise on pavement. You can still amplify range or luxury with available Max Range battery and feature packages to match a growing adventure list.
Cardinale GMC — serving Castroville, Watsonville, and Hollister — will help you tailor an AT4 to your life, from accessory racks and liners to planning home charging and selecting the right range option. Below are quick answers to popular AT4 questions.
