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.

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.

2022 GMC Hummer Edition 1 weighs 9,063 pounds

From the beginning, the Hummer line of vehicles has been synonymous with the phrase, "absolute unit." The M998 Humvee turned to civilian use as the Hummer H1 came with a curb weight of 7,560 pounds depending on configuration. The much more urbane Hummer H2 didn't sacrifice much of those gains, putting about 6,615 on the scales. Let us not forget that the behemoth gravitational pull and square-jawed mass were what every Hummer buyer wanted. So, starting with the brand values and customer demand, and adding the fact that electric vehicles are substantially heavier than their ICE counterparts, no one should be surprised that the 2022 GMC Hummer Edition 1 weighs 9,063 pounds. That's just one of the substantial figures GMC included in a self-certification filing submitted to the U.S. Environmental Protection Agency, the document rooted out by Car and Driver. Last year GMC told us the Hummer would weigh 9,046 pounds, which proves again the Freshman 15 (or 16) is unavoidable.  Loaded up with humans and their accessories, the truck's gross vehicle weight rating (GVWR) comes in at 10,550 pounds. It takes a few other big numbers to keep that kind of tonnage on the go. The Ultium battery weighs 2,923 pounds. With a 617-amp-hour capacity at 400 volts, total capacity comes in at 246.8 kWh, specific energy at 158 Wh/kg. Usable capacity is about 85% less, at 212.7 kWh. For the time being, these numbers put every other pack in a production vehicle in the shade. That gargantuan chemical plant in the Hummer's floor powers a 329-mile range the same way a giant fuel tanks feed a truck that gets 8 miles to the gallon. The miles per gallon equivalent figures GMC submitted to the EPA are 51 MPGe city, 43 MPGe highway, 47 MPGe combined. Motor Trend questioned whether GM applied the correction factor used for window sticker numbers; if not, the standard 0.7 correction drops the MPGe specs to 36 city, 30 highway, and 33 combined. However, trucks with a GVWR beyond 8,500 pounds don't need to display fuel economy figures on their window stickers, so don't expect to see any such details on dealer lots. For comparison, the Rivian R1T Launch Edition weighs about 7,000 pounds, and fits a 128.9 kWh battery good for an estimated 314 miles estimated at 70 MPGe.
