GMC’s third EV truck, when you rely the Hummer and the Hummer SUV as two separate vehicles, is the Sierra EV. The posh pickup debuted as a $100K 2024 mannequin 1 final yr and bought some modest upgrades for 2025. GMC flew us to the hills above Silicon Valley to test it out.
The GMC Sierra EV Denali shares the identical platform because the Chevy Silverado and, to a lesser extent, the GMC Hummer. Chief amongst these is the industry-leading 205+kWh battery pack. That’s round 50% greater than a lot of the competitors, making these automobiles the one recreation on the town with regards to towing heavy stuff lengthy distances with out having to recharge usually. Add to that the power to make use of Tremendous Cruise whereas trailering, Energetic Air suspension, 4-wheel steering and that is your trailering EV king.
New for 2025, the Sierra EV Denali has a whopping 460-mile vary, up from 440 miles within the 2024 mannequin. GMC remains to be utilizing the identical battery packs, however has extra environment friendly motors and software program this time round. GMC can be providing a 3900-mile “Prolonged Vary” selection for $92K. Sierra EV AT4 and Elevation are anticipated to be accessible the primary half of 2025, pricing can be introduced nearer to launch.
Even with an enormous trailer, that’s nonetheless over 200+ miles of vary or round 3 hours of driving time.

2025 GMC Sierra EV Denali expertise
GMC had a very nice course for us to take out to Half Moon Bay from Menlo Park with a lovely cease at a mountain vineyard after which a horse farm for some aggressive trials.
The large takeaway is that vary nervousness is non-existent once you begin the day with 400 miles, even when driving a lot of the day over mountains. This 760 horsepower and 785 lb-ft of torque in Max Energy mode car goes 0-60 in 4.5 seconds as properly. Even with an enormous trailer, getting on the freeway is simple. In reality, it’s straightforward to overlook you’re even trailering, particularly with the Supercruise.
Whereas we had been doing the Crab Stroll time trials and seeing how a lot stuff we might stuff into the vehicles, I couldn’t get my thoughts off of the Airstream camper show that was totally powered by the Sierra EV and will keep that means for days and even weeks.
This is perhaps the largest benefit of the 205kWh battery pack. Certain you possibly can tow a lot additional however you too can keep tenting for for much longer with that massive battery pack. I think about individuals who don’t need to be tied to a powered tenting web site would love this selection. Add some photo voltaic and you actually might reside off grid eternally with this factor.
And talking of energy, GM confirmed off its GM Vitality PowerBank which is the corporate’s reply to Tesla’s Powerwall system. It’s accessible now and may be a part of the Sierra buy.
The one factor I had an issue with was the switchover time, which was about 4-5 seconds. My Powerwall system, when it goes off Grid/Islanding, is sort of instantaneous to the purpose the place I don’t even discover it. GM stated it’s engaged on decreasing the time to modify over to off-grid when the facility goes out however didn’t make any guarantees that an instantaneous switchover can be attainable.
The wonderful thing about this method is that the monster 205kWh battery pack contained in the Sierra is built-in and might present energy for weeks. In reality, you might present energy eternally when you took the truck to a quick charger each week or so and introduced it again to energy the home and recharge the batteries.
Electrek’s take:
The spec sheet for the GMC Sierra EV Denali is fairly spectacular:
- 760 horsepower and 785 lb-ft of torque in Max Energy mode
- 800 Volt DC public quick charging-capable at as much as 350kW, enabling as much as 100 miles of vary in roughly 10 minutes

- The MultiPro MidGate expandable mattress, which gives room for hauling gadgets practically 11 ft in size, whereas nonetheless leaving room for a rear-seat passenger
- Obtainable 10,500 kilos max towing
Certain it’s a luxurious model of the Chevy Sierra however in case you are already dropping $70+ok on a 205kWh pickup truck you may as properly get air suspension, 4-wheel steering/crabwalk and a beautiful luxurious inside for 20% extra.
My massive takeaway from this journey was that the top of pickup truck luxurious is that this Sierra EV Denali. In and out, it has top-rated specs and efficiency. Nothing comes near that 205kWh battery pack, which, for vary and powering electrical, means the one competitors are GMC’s sister automobiles, the Silverado and Hummer EV.
