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.

What the electric Hummer's size and weight means for its efficiency

The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider If you think driving a pint-sized Nissan Leaf is as good for the planet as driving a huge electric Hummer, think again.  The GMC Hummer EV uses significantly more electricity than other EVs, meaning it produces more pollution upstream.  The electric Hummer weighs 9,000 pounds and its battery weighs as much as a Honda Civic. The new electric Hummer rolls through town without a deafening engine rumble or a cloud of toxic fumes, but it doesn't exactly tread lightly.  The colossal truck weighs an astonishing 9,000 pounds. (Think two Toyota Tacomas, three Honda Civics, or 24 Shaquille O'Neals.) Moreover, the GMC Hummer EV is in many ways a supersized gas guzzler for a new era. It repackages many of the same flaws of hulking SUVs and trucks of years past — and proves not all zero-emission cars are created equal. EVs can be energy guzzlers too On the whole, electric cars use less energy than gas-powered ones. But they aren't all equally efficient.  No surprise here: The Hummer needs more electricity than any other EV on the market to move its elephantine frame. The Environmental Protection Agency rates the pickup at 47 MPGe (miles per gallon of gasoline-equivalent). For comparison, the Tesla Model 3 sedan is nearly three times as efficient, earning a rating of 132 MPGe. The Ford F-150 Lightning, another electric truck, gets 70 MPGe.  This has real consequences: Since the US gets 61% of its energy from oil, coal, and natural gas, the more electricity a car needs, the more pollution it creates upstream.  As the Union of Concerned Scientists put it: "Both EV cars and trucks are much cleaner than their gasoline counterparts, but electric trucks are responsible for more global warming emissions than electric cars simply because trucks are larger and heavier."  The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider The Hummer EV is also resource-intensive to manufacture, requiring a ginormous (and weighty) battery to give people the 300-plus miles of range they desire. You could produce three Chevrolet Bolts with the same battery cells consumed by one Hummer.

Hummer H2 burns to a crisp; now the owner won't need the hoarded gas

Here's your daily Autoblog public service announcement: Don't hoard gasoline, but if you do, absolutely do not let 20 gallons of it catch fire inside your 2004 Hummer H2. You might end up, as a Florida owner learned the hard way, with a very crispy Hummer. According to CBS affiliate WABI, in Citrus County Fire Rescue was called out to the scene at a Homosassa, Florida, Texaco station yesterday morning. The Hummer owner had just filled four five-gallon jerry cans' worth of fuel and placed them in the back of the vehicle. It's not clear what started the fire, but when emergency crews arrived the SUV was already, as the kids say, fire. The vehicle was a total loss. Photos show it completely singed and missing the hood and windows. One fender sat forlornly on the ground nearby. One injury was reported, but the individual refused to be taken to the hospital. The Florida Department of Environmental Protection was called in to handle the fuel cleanup. There's been a run on gasoline across the eastern seaboard due to a shortage caused by Colonial Pipeline, one of the major refined petroleum pipelines on the East Coast. Due to lax cybersecurity measures, the company fell victim to a ransomware attack, which shut down its operations over the weekend. Hackers based in Russia demanded a payout of $5 million to release control of Colonial Pipeline's computer systems, and Colonial paid up and has since resumed operations. Between fires, fights and admonitions by politicians not to hoard — probably one of the few things Florida Gov. Ron DeSantis and President Joe Biden agree on — that's probably good advice to follow. Gas stations should be resupplied in many affected areas within days. In Tampa, Florida, a third of the city's gas stations were out of fuel on Thursday. In Miami, outages stood at nearly 40% and growing as residents rapidly filled up their tanks. The outages would make sense if the largest U.S. gasoline pipeline served those cities. But it does not. South Florida is seeing the worst outages among areas not directly impacted by the line closure. "If you want a perfect case for where hoarding has made the situation what it is, that's southern Florida," said Patrick De Haan, head of petroleum analysis at GasBuddy. "They should not be having any issues at all - they get gasoline from a barge." Statewide, about a third of gas stations are out of product, according to GasBuddy.
