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.

Build a Jeep Gladiator 392 next? The Hummer H3T Alpha blazed the trail

The 2021 Wrangler Rubicon 392 will combine the go-anywhere capability of a Jeep's iconic off-roader with the grunt of a V8 for the first time in decades. As cool as that is, we can't help but think Jeep is missing out on a huge opportunity to pair that 470-horsepower, 6.4-liter Hemi V8 with the Wrangler's pickup cousin, the Jeep Gladiator, in the form of a Mojave 392.  Autoblog took part in a media Q&A session with Jeep ahead of the Rubicon 392's announcement in which the company's product higher-ups said that there are currently no official plans to build a 392 variant of the Gladiator pickup. But whether or not Jeep has plans, it certainly has precedent, and from our perspective, a market.  Rewind to 2008, better known as one of the worst possible years to introduce a gas-guzzling, V8-powered pickup truck. Enter the 2009 Hummer H3T Alpha, the first variant of Hummer's midsize truck/SUV hybrid to be offered with a 5.3-liter V8. The 300-horsepower small-block was an upgrade to the sturdy but relatively uninspiring 3.7-liter inline-5 that the H3 lineup had inherited from its midsize pickup platform mates.  As our Jeremy Korzeniewski noted in the Rubicon 392's introductory piece, an open-top Jeep has not been offered with an optional V8 for as long as the "Wrangler" nameplate has existed. The last Jeep 4x4 to do so was still a CJ, or civilian Jeep, and the 304 cubic-inch engine came from American Motors Corporation. Incidentally, this generation of the Wrangler is also the first to be offered in a pickup variant. Cue the beard-stroking.  Now, frankly, it's not even remotely fair to compare the H3T's powertrain offerings to the decade-newer Gladiator's, but the Hummer actually boasts a few advantages over Jeep's modern pickup. While most of the Jeep's off-road specs give it an edge, the Gladiator doesn't come close to the H3T's 30.1-degree departure angle, for instance. And in more practical terms, the stubbier H3T has other maneuverability advantages. The Gladiator has 3" of wheelbase and 5" of overall length on the H3T, and a 22.4-foot turning radius to show for it. The Hummer's? Just 18.5'.

For EV drivers, realities may dampen the electric elation

The Atlantic, a decades-old monthly journal well-regarded for its intelligent essays on international news, American politics and cultural happenings, recently turned its attention to the car world. A piece that ran in The Atlantic in October examined the excesses of the GMC Hummer EV for compromising safety. And now in its latest edition, the magazine ran a compelling story about the challenges of driving an electric vehicle and how those experiences “mythologize the car as the great equalizer.” Titled “The Inconvenient Truth About Electric Vehicles,” the story addresses the economics of EVs, the stresses related to range anxiety, the social effects of owning an electric car — as in, affording one — and the overarching need for places to recharge that car. Basically, author Andrew Moseman says that EV life isn't so rosy: “On the eve of the long-promised electric-vehicle revolution, the myth is due for an update. Americans who take the plunge and buy their first EV will find a lot to love Â… they may also find that electric-vehicle ownership upends notions about driving, cost, and freedom, including how much car your money can buy. "No one spends an extra $5,000 to get a bigger gas tank in a Honda Civic, but with an EV, economic status is suddenly more connected to how much of the world you get to see — and how stressed out or annoyed youÂ’ll feel along the way.” Moseman charts how a basic Ford F-150 Lightning electric truck might start at $55,000, but an extended-range battery, which stretches the distance on a charge from 230 miles to 320, “raises the cost to at least $80,000. The trend holds true with all-electric brands such as Tesla, Rivian, and Lucid, and for many electric offerings from legacy automakers. The bigger battery option can add a four- or five-figure bump to an already accelerating sticker price.” As for the charging issue, the author details his anxiety driving a Telsa in Death Valley, with no charging stations in sight. “For those who never leave the comfort of the city, these concerns sound negligible," he says. "But so many of us want our cars to do everything, go everywhere, ferry us to the boundless life we imagine (or the one weÂ’re promised in car commercials),” he writes. His conclusions may raise some hackles among those of us who value automotive independence — not to mention fun — over practicalities.
