GMC’s third EV truck, should you 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 12 months 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 many of the competitors, making these autos the one sport on the town with regards to towing heavy stuff lengthy distances with out having to recharge typically. Add to that the flexibility 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 will likely 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. The Sierra EV Denali may also use all of these 350+kW charging stations and may add miles as quick as 100 miles in 10 minutes. We’ve seen charging speeds in extra of 360kW which should you divide the 200kWh pack in half appears fairly quick 180kW for every 100kWh sub-pack.

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 good looking 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 many of the day over mountains.
Whereas we have 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 method for days and even weeks.
This could be the most important benefit of the 205kWh battery pack. Positive you’ll be able to tow a lot additional however you too can keep tenting for for much longer with that vast battery pack. I think about individuals who don’t wish to be tied to a powered tenting web site would love this selection. Add some photo voltaic and you actually may 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 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 facility goes out however didn’t make any guarantees that an instantaneous switchover could be doable.
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 actual fact, you could possibly 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.
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
- Air Experience Adaptive Suspension, which gives the flexibility to lift or decrease the truck by about 2 inches, whereas additionally providing a extra snug journey
- The MultiPro MidGate™ expandable mattress, which affords room for hauling objects 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 if you’re already dropping $70+ok on a 205kWh pickup truck you may as nicely get air suspension, 4-wheel steering/crabwalk and a luxurious inside for 20% extra.
My huge takeaway from this journey was that the head 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.
