What's the Difference Between the 2024 and 2025 GMC Sierra EV Denali?

For 2025, the GMC Sierra EV Denali gains a smaller, more affordable Extended Range battery option with 390 miles of range, a slight power increase to 760 hp, a higher 10,500-pound towing capacity, and more color choices, while the original Max Range battery sees its estimated range increase to 460 miles.

The launch of all-electric full-size pickups from GM's brands has been a strategic, tiered approach. For the 2024 model year, both the GMC Sierra EV and Chevrolet Silverado EV debuted in high-end, fully-loaded specifications: the Sierra EV Denali Edition 1 and the Silverado EV RST First Edition. For 2025, GMC is broadening the Sierra EV's appeal by introducing a new battery option and making the top-tier Denali trim more accessible, setting the stage for more affordable variants arriving later in the year.

What Are the New Battery Options and Range for the 2025 Sierra EV?

The most significant update for the 2025 GMC Sierra EV is the introduction of a new, smaller battery pack. This pack, named the Extended Range battery, offers an estimated 390 miles of range on a full charge. The naming becomes logical when considering the Chevrolet Silverado EV's even smaller Standard Range pack. The original large battery, now called the Max Range pack, has seen its official GM-estimated range increase to 460 miles for 2025, up 20 miles from the 2024 model's estimate.

Both battery options support an 800-volt electrical architecture, which enables exceptionally fast charging at public DC fast-charging stations. GMC states that with a sufficiently powerful 350-kilowatt charger, the Sierra EV can add up to 100 miles of range in approximately 10 minutes. This capability is crucial for reducing downtime on long trips and enhances the truck's viability as a work vehicle.

How Does the 2025 Sierra EV Denali Perform Compared to the 2024 Model?

The powertrain remains a potent combination of front and rear electric motors. In the Max Power mode, which unlocks additional output for short bursts, the system produces a combined 760 horsepower and 785 pound-feet of torque. This represents a slight increase of 6 hp over the 2024 model's 754 hp. This power enables a swift 0-60 mph acceleration time of under 4.5 seconds.

A more practical upgrade for 2025 is the increase in maximum towing capacity. The Sierra EV Denali can now tow up to 10,500 pounds, an increase of 500 pounds over the 2024 model's rating. This enhancement strengthens its competitive position against rivals like the Ford F-150 Lightning.

What Key Features Come Standard on the Sierra EV Denali?

Beyond the powertrain, the 2025 Sierra EV Denali continues to offer a comprehensive suite of premium and innovative features as standard equipment. These are largely carry-overs from the Edition 1 package and include:

• Adaptive Air Suspension: Allows the ride height to be raised or lowered by approximately 2 inches for better off-road capability or easier entry/loading.
• Four-Wheel Steering with CrabWalk: The rear wheels can steer up to 10 degrees, and in a special mode, they turn in the same direction as the front wheels, allowing the truck to move diagonally at low speeds for enhanced maneuverability.
• MultiPro MidGate: A hallmark of GM's electric trucks, this feature allows the rear cab wall to be folded down, extending the cargo bed to accommodate items nearly 11 feet long while still maintaining a rear passenger seat.
• Luxury & Tech Interiors: Standard features include a fixed panoramic glass roof, quilted leather upholstery, open-pore wood trim, a 16.8-inch central touchscreen, an 11-inch digital gauge cluster, and a 14-inch head-up display.
• Super Cruise: This hands-free driver-assistance system is included, allowing for automated driving on over 400,000 miles of compatible highways in the U.S. and Canada.
• Vehicle-to-Home (V2H) Charging: The truck can power essential home appliances for up to 21 days during a power outage, acting as a massive backup generator.

What About Advanced Safety and Future Models?

The 2025 Sierra EV Denali comes with a full suite of standard advanced safety features. This includes forward collision warning with automatic emergency braking, blind spot intervention, rear cross-traffic alert, and GM’s unique Safety Alert Seat that uses vibrations in the driver's seat cushion to warn of potential hazards.

While the Denali is currently the only available trim, GMC has confirmed that more affordable AT4 (off-road focused) and Elevation trims are scheduled to arrive at dealers in the first half of 2025. These will provide entry points into the electric Sierra lineup at lower price points.

The 2025 GMC Sierra EV Denali with the Extended Range battery starts at $91,995, while the Max Range model starts at $100,495 (both prices include a $2,095 destination fee). The key takeaways for shoppers are the new, more affordable battery option, the increased towing capacity, and the blazing-fast 800V charging capability that sets it apart in the evolving electric pickup market.
