The vehicle’s capabilities became evident, particularly in handling varied terrain and cargo demands. The Max Range version can achieve up to 460 miles of range, while the Extended Range model offers 800-volt DC fast-charging capabilities, which are part of GM’s expanding charging network.
Towing capacity remains a strong suit, with the Max Range version capable of hauling up to 10,000 pounds and the Extended Range model handling 10,500 pounds. During a test with a 5,500-pound trailer, the Sierra EV maintained acceleration that outperformed a fully loaded minivan, averaging 1.0 miles per kWh. This efficiency suggests that even with heavy loads, the truck retains a substantial range—potentially 200 miles or more in scenarios involving trailers or boats.

Power delivery is impressive, with the Max Range version producing 760 hp and 785 lb-ft of torque via dual permanent magnet motors. The Extended Range model closely mirrors this hardware, though with slightly reduced power output at 645 hp. Acceleration to 60 mph occurs in 4.5 seconds in Max Power mode, though GM has not disclosed peak figures for other driving modes like Tow-Haul or Off-Road.
Cargo versatility is another standout feature. The Midgate system allows the backseat area to be converted into an extended cargo space, creating up to 10 feet 10 inches of usable length when the tailgate is down. This innovation is designed for daily use, not just occasional trips, and includes a flip-down load step for securing long items like kayaks. The 11.0-cubic-foot eTrunk in the front offers weatherproofing, a drain, and a cupholder, complementing the Midgate’s utility.
Interior comfort and luxury are emphasized in the Denali trim, which includes air suspension, rear-wheel steering, a panoramic sunroof, and heated-and-cooled front seats. The cabin’s 16.8-inch portrait-oriented infotainment system, powered by Google’s ecosystem, contrasts with the Chevrolet Silverado EV’s landscape-oriented setup. However, Apple CarPlay and Android Auto are absent, a notable omission for some users.

Advanced features like GM’s Super Cruise hands-free driving system are included, though its effectiveness in low-visibility conditions—such as faint lane markings on US-101—remains limited. The system supports towing and offers lane-keeping and speed control via regenerative braking, though reliability in complex environments is still a work in progress.
Quietness is another highlight, achieved through active noise cancellation, acoustic side glass, and additional sound insulation. The cabin’s premium finish, with laser-cut wood trim and fine stitching, reinforces its luxury positioning. However, affordability remains a hurdle, as the Denali starts at $100,495, excluding towing and storage accessories. More budget-friendly AT4 and Elevation trims are planned for 2025, though production timelines are unclear.

GM’s Energy suite adds practicality, enabling the Sierra EV to output 10.2 kW AC power for off-grid use and integrate with home energy systems via the PowerShift charger. These features aim to reduce reliance on generators, aligning with the growing demand for multifunctional EVs.
While the Sierra EV Denali excels in many areas, its high price and limited production capacity—currently relying on the Lake Orion plant, which previously built the Bolt EV—pose challenges. Nonetheless, the vehicle has surpassed initial skepticism, proving that a capable, luxurious electric truck is achievable. With further refinements and expanded availability, the Sierra EV could become a benchmark in the full-size EV segment.
