Hummer EV SUV official range announced: 3X truck tops 350 miles

The first run of GMC Hummer EVs were in one single specification: pickup truck in Edition 1 with all the off-road goodies. The most pertinent of those off-road upgrades to electric range being the 18-inch wheels with mud-terrain tires. And it was rated for 329 miles. But now, there are more Hummer variants. The pickup truck is now available with a 3X trim that comes standard with more efficient all-terrain tires wrapped around 22-inch wheels, and there's the SUV with both trims and both types of tires, not to mention a smaller battery pack. And now we have the official range estimates for them. We'll start with the Hummer EV SUV, since all of the official range ratings are new to us. The tires are the key factor, with the all-terrain equipped Edition 1 and 3X both managing 314 miles of range. Yes, this is less than even the mud-terrain-equipped truck, but that's mainly because the shorter length of the SUV means it has fewer battery cells and capacity. It has about 170 kWh of capacity versus the truck's 200+. Adding the Extreme Off-Road Package and its more aggressive tires drops range to 298 miles. The Four-Wheel-Steer system lets the 2022 GMC HUMMER EV Pickup m View 17 Photos As with the SUVs, the Hummer EV truck gets a solid range boost to 355 miles when it's not equipped with the off-road package. There's another benefit to the regular all-terrains on the Hummer EV truck: towing capacity. At 8,500 pounds, it can tow an extra 1,000 pounds over the models with the off-road package. GMC also notes that another potential benefit to the all-terrain-equipped trucks is a suspension tuned for better on-road handling. And our experience has shown that even Hummer with the off-road package isn't too shabby on pavement. Of course, skipping the off-road package will also save you some money, as will opting for the 3X trims. So unless you're really going off-road seriously, and would make regular use of the extra skid plates, under-truck camera and chunky tires, the standard suspension and tire setup really is the way to go.

2022 GMC Hummer EV dimensions, clearances and off-road features explained

There are two things that almost everyone immediately thinks of when they hear the word "Hummer." And they are size and off-road capability. Looking at the numbers on the 2022 GMC Hummer EV, it seems the electric pickup has literal truck loads of each. One of the most prodigious numbers is the truck's width. See those clearance marker lights on the roof? They aren't just there for style, they're required by law due its width. At 86.7 inches, it's just a bit wider than a Ford F-150 Raptor, which is itself 6.4 inches wider than a comparable F-150. The Hummer is also 5.5 inches wider than a GMC Sierra. Length is more reasonable at 216.8 inches, which is much less than a full-size crew cab pickup (a Sierra 1500 is 231.7 inches with its 5-foot-8-inch box or 241.2 with the 6-foot-6 one). It's even 3 inches less than the Raptor SuperCab and only 4.4 inches longer than a GMC Canyon with the standard 5-foot-2-inch box. In other words, the Hummer EV is roughly as long as a midsize pickup but is wider than a heavy-duty one.  What does that mean for the cabin? With 38.9 inches of rear legroom, it falls well short of a Sierra Crew Cab's 43.4, but it's important to remember that crew cab pickups have an overkill amount of limo-like legroom. The Hummer's amount is still 3.7 inches longer than a Sierra Double Cab and 3.1 inches longer than a Canyon Crew Cab. Headroom, which was rather pathetic in the old Hummer H2, is 38.6 inches in the back seat – less than both its GMC truck siblings, but not by much. In other words, there should be plenty of space back there. Note that GMC didn't indicate bed length, frunk volume, or importantly, curb weight. We will update this should we find out answers to any of those.  Although it's big, the Hummer has plenty of features to make it nimble off road, both traditional and high-tech. One of the primary features is the height-adjustable air suspension, which offers 13 inches of travel and automatically adjusts damping for driving conditions. It has three main levels, a lowered setting for Aero Mode that helps with improving highway energy use, a default height for the normal driving modes, and a higher setting for the off-road Terrain Mode.

GMC's Hummer EV will offer several powertrain options

General Motors confirmed plans to resurrect the Hummer nameplate on a GMC-badged electric pickup, and it's beginning to release details about the drivetrain that will power the model. Speaking to investors, company president Mark Reuss announced buyers will have at least three drivetrains to choose from at launch. The few specifications that have already been announced are impressive. GMC quoted a three-second sprint from zero to 60 mph, at least 1,000 horsepower, and 11,500 pound-feet of torque, though that latter figure undoubtedly corresponds to wheel torque rather than the powertrain's basic output. Most truck buyers don't need Lamborghini-rivaling acceleration, and they'd rather not pay for it, so GMC will also offer more basic versions of its Hummer. "When we go to market, we'll have one-, two-, and three-motor versions offering different ranges, different performance, and different price points to meet customers wherever they may be. If the customer wants a basic package, we'll have that. If the customer wants true off-road capability, and towing capability, we'll have that, too," Reuss said. He stopped short of revealing additional specifications about each configuration. While that sounds expensive to develop and certify, Reuss explained General Motors is keeping costs in check by making the Hummer's powertrain as modular as possible. He compared the platform to an ice cube tray. Its overall dimensions are fixed, but people can choose how many rows they fill with water. What he's likely alluding to is a scalable battery pack whose capacity can be increased or decreased by adding or removing cell packs. As for the motors, we're expecting the entry-level, rear-wheel drive Hummer will come standard with a single motor mounted over the rear axle. The mid-range variant will likely gain a second motor positioned over the front axle to deliver through-the-road all-wheel drive, and the range-topping trim will receive individual rear motors (though they won't be integrated into the wheels) for jaw-dropping performance, and improved off-road capacity.  Economies of scale will come into play, too. While the Hummer is the only electric off-roader whose launch has been confirmed by General Motors, Reuss stated the company's other brands will benefit from it, too. "We'll have a complete lineup of EVs, including the [Hummer EV] and its stablemates," he said.
