GMC’s third EV truck, should you rely the Hummer and the Hummer SUV as two separate vans, is the Sierra EV. The luxurious pickup debuted as a $100K 2024 mannequin 1 final 12 months and acquired 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 sport on the town in relation to towing heavy stuff lengthy distances with out having to recharge typically.

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 gorgeous cease at a mountain vineyard after which a horse farm for some aggressive trials.
The large takeaway is that vary anxiousness is non-existent while 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 automobile goes 0-60 in 4.5 seconds as properly. Even with an enormous trailer, getting on the freeway is straightforward. Actually, it’s straightforward to overlook you might be even trailering, particularly with the Supercruise.
Whereas we had been doing the Crab Stroll time trials and seeing how a lot stuff we may 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 manner for days and even weeks.
This may be the most important benefit of the 205kWh battery pack. Positive you possibly can tow a lot additional however you may also 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 website would love this feature. Add some photo voltaic and you actually may dwell off grid eternally 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 obtainable now and could 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 can be doable.
The beauty of this method is that the monster 205kWh battery pack contained in the Sierra is built-in and might present energy for weeks. Actually, you may present energy eternally should you took the truck to a quick charger each week or so and introduced it again to energy the home and recharge the batteries.

Positive it’s a luxurious model of the Chevy Sierra however in case you are already dropping $70+ok on a 205kWh pickup truck you would possibly 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. Inside and outside, 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.
