Sierra EV Denali stands out with a GM-estimated 460 miles
Midgate setup permits flexibility for objects nearing 11-feet lengthy
Versatility from air suspension, rear-wheel steering, Tremendous Cruise
“I’ve been on that route, and it’s not a route for a full-size pickup—not to mention one weighing almost 9,000 kilos.”
That was what I famous, partly in disbelief, to my co-driver as we have been proven right into a 2025 GMC Sierra EV and despatched off to wind up by way of slender Bay Space Redwood highways and stretches of Skyline Boulevard.
Reminiscence served properly concerning the roads; the route included some undulating ribbons of asphalt on ridges that I’d loved totally in a little bit Volkswagen GTI years earlier. However I fully underestimated the Sierra EV.
At about 233 inches lengthy and 84 inches extensive not counting mirrors, the large electrical truck wasn’t so nerve-wracking for tackling slender lanes. I may place it with precision, due to rear-wheel steering that pivots the rear wheels at a small angle reverse the fronts in low-speed hairpins. Prompt torque supply from the Sierra EV’s dual-motor system meant we didn’t lose momentum up the hills, whereas the air suspension stored us feeling even-keeled. Robust regenerative braking (Regular and Excessive) stored our velocity proper accurately on the steep downhill grades.

I went into the day figuring out properly this truck’s lofty vary declare of 460 miles and the way rapidly it accelerates—and I didn’t want additional proof that it will possibly blast quietly to 60 mph in 4.5 seconds (or higher, it appears). However GMC nudged us alongside the form of route I by no means would have chosen, together with loads of these curves, some towing, some in-the-dirt play with the rear-wheel steering demonstrating the astonishing maneuverability and digital camera views, and an train with CrabWalk mode, which factors the rear wheels in the identical course because the fronts. And it turned us free with the problem of becoming an entire lot of outdoor-fun gear into the Sierra EV in a rush.
By the top of the day, I felt schooled. GMC hasn’t made a unusual design assertion (that’s the Cybertruck), aimed for the outside way of life crowd (that’s the R1T), or just made an electrical model of its top-selling truck (that’s the F-150 Lightning).
The GMC Sierra EV sits subsequent to the GMC Hummer EV within the GMC lineup, and the model primarily separates the 2 by saying that if the Hummer EV pickup is the “it” truck, the Sierra EV is the “do it” truck. As a product, it’s a extra spectacular accomplishment for the market, and if you happen to’re on the lookout for probably the most cargo versatility for big objects, and probably the most vary for towing, hauling, and doing trucky issues, that is it.

2025 GMC Sierra EV: Wide array for a “do it” truck
The 2025 GMC Sierra EV has a number of the market’s highest vary rankings, not as a result of it’s a standout for effectivity however as a result of it goes large on its battery packs. Each battery packs are dual-layer, with the potential to sew the 2 layers collectively in sequence to permit 800-volt DC fast-charging. The Max Vary’s 205 kwh, it achieves vary rankings of 460 miles, and the Prolonged Vary’s 170 kwh affords 390 miles. The Max Vary quantity is “GM-estimated,” as a result of that super-sized pack throws the Sierra EV right into a medium-weight class that doesn’t apply to EPA rankings.
Over almost 90 miles of extensively diversified road and freeway driving, we noticed 1.9 miles per kwh in keeping with the Sierra EV’s journey laptop—suggesting we’d nonetheless see 390 miles of vary or extra in this sort of driving.
The massive battery opens up potentialities. The Sierra EV can tow as much as 10,500 kilos with the Prolonged Vary pack or 10,000 kilos with the Max Vary pack, and whereas it would halve the vary, that’s not a lot of a difficulty right here.

In a brief loop with a 5,500-pound trailer, the Sierra EV appeared largely unfazed by the load, nonetheless able to accelerating faster than a completely loaded minivan. On a loop with two full-acceleration faucets, it averaged simply 1.0 miles per kwh, in keeping with the journey laptop—nonetheless indicating that 200 miles of vary is feasible with a horse trailer or massive boat.
Max Vary variations just like the one I drove ship as much as 760 hp and 785 lb-ft of torque, through two everlasting magnet motors which might be designed and constructed by GM. Prolonged Vary variations have primarily the identical {hardware}, apart from the battery pack, however make 645 hp and 785 lb-ft.

These energy numbers, and the 4.5-second acceleration time for the Max model, are solely delivered when in Max Energy mode. The Sierra EV additionally has Regular-Tour, Off-Street, Tow-Haul, and a personalized mode. GM wouldn’t say what peak energy is in any of these different modes.
The Sierra EV has an 11.0-cubic-foot frunk—known as the eTrunk right here, with a cupholder, a drain, weatherproofing, and extra. However the shock cargo-versatility star right here is the Midgate. In only a few minutes you possibly can convert the backseat space into an growth of the cargo mattress—making a 9-foot-1-long house with the tailgate locked, or a 10-foot-10 house with the tailgate down and the flip-down tailgate load step used to backstop lengthy objects—like a kayak.
Engineers emphasised that the Midgate isn’t meant as an answer to solely use from time to time, fairly one thing you would possibly use day by day. Whereas it’s not weatherproof, in fact, it’s an ideal answer for bringing gear just a few miles to a launch level—with out having to get specialised carriers—and you’ll go away one of many backseat positions in place whereas utilizing it.

Sierra EV Denali is dear, however very properly geared up
The GMC Sierra may be very intently associated to the Chevrolet Silverado EV RST, however there are some key variations in the way it suits into the EV market and the truck market. In 2024, the Sierra EV was solely provided in its prime Denali trim, with what’s primarily “the works”—the largest battery pack, the air suspension, rear-wheel steering, and a characteristic set that’s one of the crucial luxury-focused amongst full-size pickups.
For 2025, there have been just some slight worth adjustments, the addition of the Prolonged Vary model, and 20 miles extra for the Max Vary model attributable to some effectivity enhancements to the motor items themselves. My day was spent with the highest Sierra EV Denali model, in Max Vary kind, costing a minimum of $100,495—together with the $2,095 vacation spot charge however not any further equipment for towing and storage.
The Sierra EV Denali contains the air suspension, rear-wheel steering, a panoramic sunroof, heated-and-cooled entrance seats, leather-based upholstery, a heated steering wheel, heated outboard seats, a head-up show, wi-fi hotspot compatibility, and seven-speaker Bose audio. There’s additionally wi-fi charging cleverly built-in right into a sliding heart console tray, plus loads of USB-C ports and a 120-volt AC cabin retailers. As well as there’s the 7.2-kw AC Offboarding Energy station that may get rid of the necessity to take that small generator out to the campsite or job website.
I didn’t get the prospect to cost the Sierra EV as a part of this temporary take a look at drive. Peak fast-charging charges are listed as 350 kw for the Max Vary pack and 300 kw for the Prolonged Vary pack. GM says that on a 350-kw CCS connector it is going to get well as much as 100 miles of vary in simply 10 minutes, and it’s stated earlier than that both of those packs will get from 10-80% in about 40 minutes. GMC integrates a battery preconditioning characteristic to assist obtain peak charges; it really works with the native navigation journey planner or through the press of a digital button.

Prepared for backing up the house, not Apple CarPlay
Within the give-and-take of EV dwelling, the Sierra EV additionally contains the potential to output 10.2 kw AC, probably eliminating the necessity to tote round a generator. And beginning with the $1,699 PowerShift charger, homeowners can outfit their dwelling with GM power elements that might use the Sierra EV to assist backup the house—together with PowerBank dwelling power storage.
Whereas the GMC Sierra EV Denali shares a lot with the Chevrolet Silverado EV, one of the crucial pronounced cabin variations is that the Sierra EV will get a 16.8-inch portrait-oriented system as an alternative of the Chevy’s panorama orientation. Identical to within the Silverado EV and different new GM EVs, it’s made with Google built-in, together with the potential to run Google-ecosystem apps—however there’s no Apple CarPlay or Android Auto compatibility or integration.

GM’s Tremendous Cruise can also be included (for 3 years) within the Sierra EV, permitting hands-off driving plus semi-automated lane adjustments on greater than 750,000 miles of mapped roads and highways—with maintained driver consideration. Tremendous Cruise additionally now works when towing. With the 5,500-pound load, I engaged the characteristic briefly and located regular lane positioning and stable velocity management utilizing the regenerative braking. However it’s nonetheless not an ideal system or one to depend on on a regular basis; once I tried to make use of the system to cruise on US-101 round Palo Alto, it stored disabling itself because it couldn’t see the faint-and-inconsistent lane markings that we had no situation seeing.
GMC has managed to accommodate tall folks so properly in entrance and in again, permitting loads of headroom and an ideal view outward. Seats are plush but supportive entrance and rear.
The cabin is super-quiet, aided by three issues: an active-noise cancellation operate for the Bose audio system, further noise padding beneath in comparison with GMC’s different fashions, and acoustic aspect glass. It provides as much as the atmosphere of a luxurious car.
That atmosphere holds on this Denali model, with fantastic stitching particulars within the entrance perforated seats, patterned speaker grilles, laser-cut wooden trim, and a good match and end all through. We’ll see if these requirements maintain for the less-expensive variations to come back.

Extra GMC electrical vehicles on the way in which—however when?
GMC has stated that extra inexpensive Sierra EV AT4 and Elevation fashions are due in 2025, though it hasn’t confirmed whether or not that will probably be for the 2025 or 2026 mannequin yr. GM additionally hasn’t given an replace on when it plans to ramp up manufacturing of those vehicles at its Lake Orion, Michigan, plant the place it ceased constructing the Bolt EV almost a yr in the past. Till then, output will probably be restricted.
However it’s straightforward, additionally, to check an much more kitted-out model of the Sierra EV with magnetic experience—to quell the hold-on-tight, amusement-park-ride feeling you get within the Sierra EV when accelerating quickly on imperfect pavement. Maybe these are the adjustments that can elevate this platform for the upcoming Cadillac Escalade IQ.
GM has overcome plenty of preconceptions—together with my very own—and proven what an ideal electrical truck it will possibly make. Now it must make extra of them.
