2025 GMC Sierra EV Denali brings big power and an equally big battery
Powering the 2025 GMC Sierra EV Denali is GM’s Ultium platform, which they have announced will be renamed soon. They estimate that in Max Power mode, the Sierra EV Denali puts out 760 hp and 785 lb-ft of torque with a 4.5 second 0-60 mph time.
A full charge provides a range of 440 miles, and with 800-volt DC fast charging at up to 350kW, GMC claims drivers can gain up to 100 miles of range in just 10 minutes of charging.

The sizeable battery can also power your home for up to 21 days, provided that your daily energy consumption is lower than normal. The optional GM Accessories PowerBar+ also provides access to up to 10.2 kW of power for your equipment or tools when a standard electrical outlet isn’t available.
Sierra EV Denali sports an impressive towing capacity and extended bed
Towing should be a breeze thanks to its claimed 10,000 lb towing capacity. How much that will affect the range has not yet been disclosed. The Multipro Midgate extends the bed to a maximum length of 10′ 10″ when the rear seats are folded down and the rear window is removed, allowing you to haul more cargo. Given that it uses the same Ultium platform, the Sierra EV Denali inherits the 4-wheel steer and CrabWalk from the brand’s Hummer EV.

Luxurious cabin with plenty of upper-class amenities
The cabin houses the same 14” digital cluster and a 16.8-inch infotainment screen as the 2024 model. The interior surfaces are adorned with open-pore wood, a quilted pattern on the seats, and perforated accents on the doors. Overhead is an infrared and UV-coated panoramic glass roof for an “open-air ambiance.” All things considered, it looks like a pretty comfy place to be on long rides.
Working towards bridging the EV truck gap
GMC
The 2025 GMC Sierra EV Denali proves itself to be more than just a flashy badge. Yes, it’s an electric truck and yes, it starts pushing into six-figure territory, but you’re getting legitimate muscle to go along with that price tag. Its 10,000-lb towing capacity is no empty claim, and the sort of comfort and upscale detailing it brings to the segment were once found only in premium SUVs.
Yes, long-haul towing is still a challenge as EV infrastructure catches up, but the Sierra EV Denali demonstrates that we’re moving past the era where electrification meant compromising on real-world utility. As battery technology continues to evolve, the idea of a powerful, refined, and fully electric truck that won’t leave you stranded seems less like wishful thinking and more like the new normal.
