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.

An all-electric Hummer is reportedly under consideration at GM

GM is reportedly considering a return to the Hummer brand, but not in the traditional Hummer way. No, a report from Bloomberg says that GM is mulling over the idea of building an electric Hummer. The report cites unnamed sources within GM, as the folks prefer not to be named due to the private nature of the conversations. At this point, Bloomberg characterizes the Hummer talks as preliminary discussions. GM is figuring out how it wants to organize its future electric trucks and SUVs, and Hummer is a part of those discussions. Just as anyone would expect, Hummer could be used to profit off the current demand for rugged and tough vehicles. Mark Reuss didn't commit either way to a Hummer revival when asked by Bloomberg. "I love Hummer. I don't know. We're looking at everything," Reuss said. Other GM sources said that the company sees an opportunity to compete with Jeep for off-road vehicles that have creature comforts commanding high premiums. The report states that designers have done work with Hummer concepts, experimenting with Hummer styling to implement it on GMC-branded products, too. There's also the question of whether an electric Hummer is a smart move to begin with. Folks bought up Hummers before because they're big, brawny, good off-road, and gas was cheap. Gas is relatively cheap today, but attitudes around cars that achieve 10 mpg have changed. Rivian thinks that consumers are interested in premium electric SUVs and trucks, and the hype around that company is real right now. An electric Hummer would undoubtedly go after the same space as the Rivian R1S. The number of people willing to drop over $70,000 on an electric adventure vehicle is still untested, though. Even if GM did give an electric Hummer project the green light, we're still years away. We know GM is currently in development of an electric pickup truck platform, but that doesn't mean it's anywhere close to production. We haven't seen a new Hummer since GM halted sales of the brand in 2010. The recession and high gas prices drove sales down so low that Hummer declared bankruptcy in 2009, but GM still kept the brand in its portfolio. It's hard to think of a better time than the SUV and crossover hoopla of today to introduce something like an electric Hummer, but until we hear something more substantial from GM, the vehicle is going to remain a rumor.

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.
