The 2022 GMC Hummer EV is by no signifies an efficiency exemplar.
In current weeks, EPA certification documents had been produced readily available for the Hummer EV, and they place precise numbers on what we currently knew would be this massive electric truck’s Super Size dimensions, capacities, and consumption.
That brought on a different round of quite vital assessments of the Hummer EV—with some fixating on a point that it is downright wasteful. The much more we know, the simpler it is been for green-vehicle forms and EV enthusiasts to demonize this GM’s electric “supertruck,” weighing in at much more than 9,000 pounds, as an analog of all that is incorrect with EVs.
I am going to contemplate carbon footprint and greenhouse gas emissions. But very first, with concentrate drawn back, if you fixate only on the Hummer EV’s weight and waste versus other EVs, you are missing the point. Here are some arguments for why the Hummer EV essentially tends to make some green sense in spite of its excess.

It’s often going to be a low-volume model. GM has hinted all along that the GMC Hummer EV is not intended to be a mass-market place model. It’s the Chevy Silverado EV and GMC Sierra EV that will arrive in higher volume. And it is affordable to assume they’ll be considerably much more effective.
It’s a “poster vehicle.” Did you have a Ferrari on your bedroom wall? A ZR1? A Raptor? Poster automobiles are often about excess, and the Hummer EV is no exception. Isn’t it much better to aspire to an electric truck?
It appeals to the “brodozer” crowd. What matters is that the Hummer EV appears even much more capable than its gas-guzzling predecessors. As such, it is conducting a ground offensive that is swaying opinions on EVs for these who may well otherwise be the toughest to convince. For these who see the kings of the road as heavy-duty diesel pickups with emissions defeat devices that enhance functionality and smoothness to the detriment of emissions, whilst “rolling coal” along the way, we believe the Hummer EV tends to make the ideal appeal but. You will not locate the uppity undertones of a Tesla Cybertruck or a Rivian R1T it is a Hummer.
Nearly just about every 1 signifies 1 significantly less gasoline truck. It’s not replacing far much more effective electric automobiles. GMC has produced clear that the Hummer EV is aimed at truck enthusiasts—including a complete line of accessories made in parallel with the automobile.

So why is the Hummer EV much better for the planet than a gasoline truck?
First, let’s get previous the shock and awe of the numbers. The most up-to-date round of certification documents revealed some essential stats about the battery pack—that it weighs two,923 pounds itself, with a respectable certain power of 158 watt-hours per kilogram. Further, the double-decker pack has a total battery volume listed at 1,012.five liters—the space of much more than ten of the 26-gallon fuel tanks common to complete-size trucks.
To place it a different way, the Hummer EV has much more than ten instances the gross battery capacity of an original Nissan Leaf. And the battery pack alone in the new GMC Hummer EV weighs much more than a total 2022 Toyota Corolla Hybrid sedan.
Would you rather be observed in either of these eco-warriors? This is indirectly GM’s complete argument.

In a certification summary document, battery power capacity is listed at 617 wh, with the pack voltage at 400 volts—suggesting a gross battery capacity of almost 247 kwh.
Usable capacity, primarily based on earlier calculations, is anticipated to be about 213 kwh. The EPA claims to have place 234.17 kwh of “recharge occasion energy” into the Hummer EV—a figure that involves any losses at the onboard charger and tends to be about ten% higher than the usable capacity. So it reinforces that GM’s accurate usable variety remains in this ballpark—greater than the “about 200 kwh” the corporation initially indicated.
Less lifetime CO2 emissions than a gas compact vehicle. Really.
Napkin math on the Hummer EV’s suspected carbon footprint versus other EVs appears abysmal. At its EPA variety of 329 miles and 213 kwh, it is obtaining just more than 1.five miles out of just about every kwh—roughly a third the efficiency of the Lucid Air Grand Touring’s four.six mi/kwh. Plus it carries about roughly double the valuable battery-pack raw supplies of other lengthy-variety EVs to date.
Electric cars are, in the operation sense, as clean as the electrical energy you plug into. So the Union of Concerned Scientists has lengthy studied the lifetime carbon footprint of EVs compared to internal combustion cars, incorporating details about the nation’s energy generation mix.

Based on the organization’s final update on EV emissions and comparative ICE mpg, David Reichmuth, senior engineer for the UCS Clean Transportation Program, estimated that the Hummer EV has roughly half the efficiency of an typical EV in its calculations. Thus, it is about the equivalent—in a quite “general” sense—of a 67-mpg gasoline automobile in California or a 46-mpg automobile across the U.S. as a complete.
Or, in Michigan, exactly where the Hummer EV is constructed, it may well be the equivalent of about a 27-mpg gasoline automobile.
The F-150 Lightning is far much more effective than the Hummer EV—with up to a 300-mile variety from 131 kwh. Last year Reichmuth’s evaluation recommended that the Lightning is the equivalent of an 85-mpg gasoline vehicle in CO2 footprint, with 70% of the U.S. population in a spot in which the electric truck would create significantly less than half of the GHG emissions than the gasoline version.
Cradle to grave: A cleaner grid counts for a lot
That’s just the consumption-and-use side—including energy generation and electrical energy distribution losses. The Hummer EV expenses much more power and sources to create, too—especially its battery pack. A 2018 paper by the International Council on Clean Transportation, rounded up a variety of academic analysis hunting at the effects of battery manufacturing on EV life-cycle greenhouse-gas emissions. It estimates that a 50% bigger battery pack will improve the life-cycle CO2 of a automobile by 18%.
In a closer appear at manufacturing emissions in 2015, the UCS located that it took just six months to 18 months of common driving to offset the extra emissions of manufacturing for EVs. A current study from the University of Michigan and Ford claims a breakeven time of just 1.three years for pickups primarily based on typical automobile miles traveled.
The Ford-supported Michigan study claims to include things like cradle-to-grave assessments, but it is unclear how far upstream in the provide chain it looks—in elements like uncommon-earth sourcing, for instance. According to it, sedan, SUV, and pickup EVs have about 64% decrease cradle-to-grave greenhouse gas emissions compared to equivalent gasoline cars. It also concludes that replacing an ICE pickup with an electric 1 saves the most CO2 more than its lifetime versus other automobile types—the equivalent of 74 metric tons.

Back on the use side, it is worth maintaining in thoughts that the nation’s energy grid is cleaning up swiftly. UCS noted that from 2018 to 2021 its estimate of EV-associated use emissions is about 15% decrease.
“If that is the automobile that is essential, and you are switching from gasoline to electrical energy, that is a net savings,” mentioned Reichmuth, noting that even if you are switching from a Honda Fit to a Ford F-150 Lightning (or, yes, a Hummer) there’s going to be some CO2 savings—albeit significantly less than if you’d switched to a Tesla Model three.
Will practicality prevail anyway?
And that leads to a quite critical point: The Hummer EV, just in some of the garage-straining beginning points and functionality-automobile targets, fairly considerably assures that it is going to stay a niche model.
“Most folks are going to want and require anything smaller sized in their garage,” mentioned Reichmuth. “I believe it is much more a matter of generating positive that there’s these mainstream vehicles—whether that is automobiles or the little crossover SUVs that are the most well known segment in the market place. Electrifying that is of considerably much more concern than this sort of volume outlier.”
Reichmuth underscores that basically place, you must get the most effective and least heavy automobile that suits your needs—and commonly these are 1 and the exact same. If you require a Ford F-150, and that is the automobile that is essential, it is a big net savings for the planet to go electric—and encourage your close friends in F-150s to do so as well.
For now, the humongous battery pack is in itself the Hummer EV’s personal market place limitation, says Reichmuth.
2024 GMC Hummer EV SUV
GMC does have lighter, much more cost-effective versions of the Hummer EV on the way—including the SUV version, and a base version that will have a smaller sized pack and will expense $79,995, due in 2024.
Some of these models will not be qualifying as heavy-duty trucks like these initial versions—which could be a explanation GM went ahead and filed a complete suite of certification documents with the EPA.
And probably it will enable illustrate just how considerably much more effective, when you place aside some of the “supertruck” ego, the corporation can make its upcoming complete-size electric pickups. GM deserves some of the flak it is obtaining more than the sheer impracticalities of the Hummer EV’s size and weight. But that does not bely the point that going exactly where no EV has gone just before is most undoubtedly a great point.
