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.

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.

General Motors has tried to cast Hummer in a greener light before

Rumors claim General Motors will resurrect the Hummer name on an electric pickup truck by 2022, and GM allegedly will preview the model with an ad starring basketball star LeBron James during the 2020 Super Bowl. If accurate, the move would represent a stunning 180-degree turn for a nameplate long associated with war-like gas-guzzlers. It wouldn't be the first time the automaker has tried to cast Hummer in a greener light, however. In 2004, when mass electrification looked as realistic as George Jetson's flying car, Hummer collaborated with Quantum Technologies to build a one-off H2 SUT named H2H powered by hydrogen. Engineers modified the stock H2's 6.0-liter V8 to run on compressed hydrogen stored in three carbon fiber tanks, and added a supercharger to offset the loss of power. The eight-cylinder made 180 horsepower, compared to 325 horsepower in the gasoline-powered model, and the truck's 12-pound hydrogen storage capacity gave it a 60-mile range. "The H2H was created for two purposes. It brings focus and attention to the journey to a hydrogen economy, and it will provide GM with key learnings on hydrogen storage, hydrogen delivery systems, and hydrogen refueling infrastructure development," explained Elizabeth Lowery, the company's then-vice president of environment and energy. She emphasized the H2H's experimental vocation and said there were no plans to bring it to production. Actor, then-California governor, and devout Hummer fan Arnold Schwarzenegger celebrated the H2H as a vision of the future after taking it for a spin. It didn't have much of a future, as it turns out, and it remained a prototype. Fast-forward to 2009, less than a year before Hummer shut down after the Chinese government vetoed a proposed sale to Sichuan Tengzhong Heavy Industrial Machinery Company. General Motors teetered on the brink of bankruptcy, it had much bigger worries than Hummer's fuel economy, so the task of making a greener truck fell into the lap of suppliers. FEV and Raser joined forces to build a plug-in hybrid prototype based on the H3. Its powertrain was built around a turbocharged, 2.0-liter EcoTec engine related to the unit found in the Chevrolet HHR SS and the Pontiac Solstice GXP, among other cars. In this application, it powered a 100-kilowatt generator that zapped a 268-horsepower electric motor into motion. Output traveled through the H3's stock four-speed automatic transmission and four-wheel-drive system, including the transfer case.
