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.

Watch the 2022 GMC Hummer EV launch using its Watts to Freedom mode

It’s nearly the July Fourth weekend, and GM is celebrating Independence Day a little earlier than most. The celebration comes in the form of a GMC Hummer EV demonstrating Watts to Freedom, or WTF, mode for us on video. You can watch it at the top of this post, but the idea is rather simple. ItÂ’s just a video of a Hummer development vehicle accelerating as quickly as it can from 0-60 mph and beyond. GMC claims its 1,000-horsepower electric Hummer is capable of hitting the 0-60 mph mark in “approximately 3 seconds,” which is borderline terrifying for how large of a vehicle it is. The super-quick time is possible when using the Watts to Freedom launch control mode, which “channels the propulsion systemÂ’s tremendous power into acceleration bursts.” The truck will still be plenty fast when accelerating normally, but WTF mode is what you should use to unlock its full potential. GMCÂ’s video shows us the graphics it uses in the digital cluster to signal Watts to Freedom is activated, and the whole sequence looks like it leans on U.S. military themes for both design and phrasing. For example, GMC lets you know that Watts to Freedom is ready via an “Armed” message in the cluster.  The 2022 GMC HUMMER EV is a first-of-its kind supertruck develop View 40 Photos Instead of a rumbling exhaust and screeching tires, the Hummer appears to silently launch with all four tires grabbing on and catapulting the truck away. It looks quick as it throws all of the weight rearward into an accelerative squat. And in case you missed it, thatÂ’s a lot of weight — GMC says itÂ’ll tip the scale at 9,046 pounds. GMC has previously said that production will begin in late 2021, and this video continues to confirm that timeframe with a note saying “initial availability Fall 2021.” Do keep in mind that only the sold-out Launch Edition is coming at that time. Other cheaper variants will follow in the years to come. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

GMC's electric Hummer could someday serve alongside the Humvee in the U.S. Army

Every civilian Hummer model traces its roots to AM General's Humvee, which made its combat debut when the United States invaded Panama in 1989. Fast forward to the 2020s, and the tables have turned. The born-again Hummer that will arrive with an electric powertrain and a GMC emblem could spawn a military-spec truck. "[The upcoming Hummer] is a full-size truck with 400 miles of range and 1,000 pound-feet of torque, it's a very highly capable vehicle. That could provide a great base platform for an electric vehicle to be used in the military context," said David Albritton, the president of General Motors Defense, in an interview with GM Authority. Although he didn't sketch out the Hummer's role in a battalion, its range, torque, and dimensions would theoretically make it well-suited to carrying soldiers, weapons, and/or gear like radio equipment. It wouldn't necessarily look like the production model (shown above in a preview image). General Motors Defense might use its basic platform and its powertrain technology to build a purpose-designed off-roader, like it did with the Colorado Infantry Squad Vehicle (ISV) it will soon begin manufacturing for the Army. The ISV shares 90% of its parts with the regular-production Chevrolet Colorado, but the two vehicles look nothing alike. Securing a contract with the American military is easier said than done, and Army officials haven't publicly expressed an interest in sending the upcoming Hummer into a war zone. We'll learn more about what a battle-ready electric truck could look like after the showroom-bound model makes its debut. In the meantime, Humvee production continues, and AM General introduced a comprehensively updated model named NXT 360 in 2018. Related Video:     Green GMC Hummer Truck Electric Military
