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.

REWIND: Watch the GMC Hummer EV live reveal right here

It has been a long wait to see the GMC Hummer electric pickup truck, which was teased way back at the Super Bowl in February of this year. And that wait ends tonight at 8 p.m. eastern time when GM pulls the covers off the truck. You can see the whole reveal right here, or during the World Series on Fox or "The Voice" on NBC. For everything we know about the truck, go to our reveal post here. The truck should be impressive. GMC has previously announced it will have up to 1,000 horsepower, and it will have a variety of fun features such as removable roof panels and four-wheel steering that can move the truck sort of sideways with "Crab Mode." The GMC Hummer will also be available in pickup and SUV forms. So be sure to tune in tonight for one of the biggest (figuratively and literally) vehicle reveals of the year. And keep an eye on Autoblog for all the latest on the Hummer and other vehicles.

Build a Jeep Gladiator 392 next? The Hummer H3T Alpha blazed the trail

The 2021 Wrangler Rubicon 392 will combine the go-anywhere capability of a Jeep's iconic off-roader with the grunt of a V8 for the first time in decades. As cool as that is, we can't help but think Jeep is missing out on a huge opportunity to pair that 470-horsepower, 6.4-liter Hemi V8 with the Wrangler's pickup cousin, the Jeep Gladiator, in the form of a Mojave 392.  Autoblog took part in a media Q&A session with Jeep ahead of the Rubicon 392's announcement in which the company's product higher-ups said that there are currently no official plans to build a 392 variant of the Gladiator pickup. But whether or not Jeep has plans, it certainly has precedent, and from our perspective, a market.  Rewind to 2008, better known as one of the worst possible years to introduce a gas-guzzling, V8-powered pickup truck. Enter the 2009 Hummer H3T Alpha, the first variant of Hummer's midsize truck/SUV hybrid to be offered with a 5.3-liter V8. The 300-horsepower small-block was an upgrade to the sturdy but relatively uninspiring 3.7-liter inline-5 that the H3 lineup had inherited from its midsize pickup platform mates.  As our Jeremy Korzeniewski noted in the Rubicon 392's introductory piece, an open-top Jeep has not been offered with an optional V8 for as long as the "Wrangler" nameplate has existed. The last Jeep 4x4 to do so was still a CJ, or civilian Jeep, and the 304 cubic-inch engine came from American Motors Corporation. Incidentally, this generation of the Wrangler is also the first to be offered in a pickup variant. Cue the beard-stroking.  Now, frankly, it's not even remotely fair to compare the H3T's powertrain offerings to the decade-newer Gladiator's, but the Hummer actually boasts a few advantages over Jeep's modern pickup. While most of the Jeep's off-road specs give it an edge, the Gladiator doesn't come close to the H3T's 30.1-degree departure angle, for instance. And in more practical terms, the stubbier H3T has other maneuverability advantages. The Gladiator has 3" of wheelbase and 5" of overall length on the H3T, and a 22.4-foot turning radius to show for it. The Hummer's? Just 18.5'.
