GMC’s third EV truck, for those who depend the Hummer and the Hummer SUV as two separate vans, is the Sierra EV. The posh pickup debuted as a $100K 2024 mannequin 1 final yr and received 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 autos the one recreation on the town relating to towing heavy stuff lengthy distances with out having to recharge typically. Add to that the power to make use of Tremendous Cruise whereas trailering, Lively Air suspension, 4-wheel steering and that is your trailering EV king.

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 wonderful cease at a mountain vineyard after which a horse farm for some aggressive trials.
The massive 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 nicely. Even with an enormous trailer, getting on the freeway is simple. In reality, it’s simple to neglect you’re even trailering, particularly with the Supercruise.
Whereas we have been doing the Crab Stroll time trials and seeing how a lot stuff we might stuff into the vans, I couldn’t get my thoughts off of the Airstream camper show that was absolutely powered by the Sierra EV and will keep that approach for days and even weeks.
This is perhaps the largest benefit of the 205kWh battery pack. Positive 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 feature. Add some photo voltaic and you actually might stay off grid without end with this factor.
And talking of energy, GM confirmed off its GM Power PowerBank which is the corporate’s reply to Tesla’s Powerwall system. It’s out there now and will 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 nearly instantaneous to the purpose the place I don’t even discover it. GM stated it’s engaged on lowering the time to modify over to off-grid when the ability goes out however didn’t make any guarantees that an instantaneous switchover could be potential.
The wonderful thing about this technique is that the monster 205kWh battery pack contained in the Sierra is built-in and may present energy for weeks. In reality, you might present energy without end for those who 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

- 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
Positive it’s a luxurious model of the Chevy Sierra however in case you are already dropping $70+okay on a 205kWh pickup truck you may as nicely get air suspension, 4-wheel steering/crabwalk and a stunning 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 autos, the Silverado and Hummer EV.
