Spy Shots Reveal GMC Sierra EV AT4 And Chevrolet Silverado EV Trail Boss

Spy photographers recently captured images of the highly anticipated GMC Sierra EV AT4 and its Chevrolet counterpart, the Silverado EV Trail Boss. The photos offer an early look at General Motors' electric pickup trucks, highlighting their rugged off-road styling and oversized tires.
GMC Sierra EV AT4 Prototype Nears Production-Ready Status
The GMC Sierra EV AT4 prototype captured in the spy photos appears nearly production-ready. While the overall design closely resembles the standard Sierra EV, sharp-eyed observers will spot the distinctive bright red recovery hooks on the front bumper, a signature feature of the AT4 trim level.
The GMC Sierra EV AT4 also showcases body-colored fender flares with built-in marker lights, enhancing both style and off-road capabilities. The finished look suggests General Motors is making solid progress toward bringing this anticipated electric truck to market, with the production version expected to closely mirror what's shown in the spy shots.

Massive Tire Size on the GMC Sierra EV AT4
The GMC Sierra EV AT4 stands out with its tire size. The spy shots clearly show 18-inch wheels fitted with 285/75R18 Goodyear Wrangler Territory AT tires, measuring 35 inches in diameter. These oversized tires give the GMC Sierra EV AT4 added ground clearance and off-road capability. The choice of all-terrain rubber underscores the truck's focus on handling rough terrain and varied conditions.
Chevrolet Silverado EV Trail Boss Shares Similar Off-Road Features
The Chevrolet Silverado EV Trail Boss was recently spotted in spy photos alongside the GMC Sierra EV AT4. Both trucks appear to share off road features, including the red recovery hooks and large all-terrain tires. One notable difference: the Silverado EV Trail Boss doesn't use body-colored fender flares like the GMC Sierra EV AT4. That styling contrast may appeal to buyers who prefer a more distinctive look on their electric off-road truck.

Pricing and Specifications Remain a Mystery
The spy photos offer a preview of the design and tire sizing for both the GMC Sierra EV AT4 and Chevrolet Silverado EV Trail Boss, but pricing and full specifications remain unconfirmed. Industry analysts expect these off-road-focused electric trucks to be priced below the high-end First Edition models, which currently range from $95,000 to $110,000.
Both trucks are expected to deliver strong performance, likely through dual-motor setups producing over 500 horsepower and 600 pound-feet of torque. Some speculation suggests the Sierra EV AT4 could inherit the powertrain from the top-of-the-line Sierra EV model, which delivers an impressive 754 horsepower and 785 pound-feet of torque.
Battery Pack Options and Range
Speculation continues around battery options for the GMC Sierra EV AT4 and Chevrolet Silverado EV Trail Boss. Early versions of these trucks are projected to come with a 204 kWh battery pack, offering solid range for both on- and off-road driving. There's also talk that GMC could offer a smaller 170 kWh pack as a more budget-friendly alternative for the GMC Sierra EV AT4.

Final Thought
The spy shots of the GMC Sierra EV AT4 and Chevrolet Silverado EV Trail Boss have generated plenty of buzz among truck enthusiasts. Both trucks are drawing attention for their off-road capability, aggressive tire sizing, and electric powertrains, all of which could shake up the electric pickup segment.
Industry watchers and consumers alike are eager to learn more about pricing, specifications, and battery options as the official reveal approaches. With the electric truck market gaining momentum, both models are expected to make a strong impression once they arrive.
