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.

GM SUV window switch recall urges owners to park vehicles outside

It's not unusual for there to be a lag between an automaker announcing a recall and the official documentation showing up on the National Highway Traffic Safety Administration website. So it's no surprise that a recent GM campaign took about a month to appear in its official capacity. However, there appears to be some big differences between the two reports with potential safety implications.
In late June, GM announced that it needed to recall 181,984 examples of the Chevrolet Trailblazer, Buick Rainier, GMC Envoy, Isuzu Ascender and Saab 9-7x from the 2005-2007 model years, plus the 2006 Chevy Trailblazer EXT and 2006 GMC Envoy XL. The new documents paint a slightly different picture with 184,611 needing repaired and different model years listed.
The reason for the fix is still the same, though. It's possible for fluid to contact the master power window switch module in the driver's door, which can corrode the part. Eventually this could cause a short circuit, leaving the buttons inoperable and potentially leading to a fire. But the new NHTSA documents add an important note: "A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made."

GMC Hummer EV infotainment built with Unreal Engine used by 'Fortnite' and 'Rocket League'

We're only a couple weeks away from the reveal of the GMC Hummer EV truck and SUV. And we're expecting a lot of boasting about impressive capability and unique features. What we weren't expecting was for its infotainment system to be built on a video game engine. That's the news that has come out of Epic Games, creators of Unreal Engine, the basis of the Hummer's infotainment system. If you've been an avid video gamer anytime in the last 20 years, Unreal Engine should be recognizable. The first version of it powered Epic's "Unreal" and "Unreal Tournament" games, and more recent versions power multiplayer hits such as Epic's "Fortnite" and Psyonix's "Rocket League." The engine has been licensed out to countless other game developers for titles by both indie developers and large game companies. But its use in the GMC Hummer will be the first time it has powered a production car's infotainment system. This content is hosted by a third party.

Presumably it's a version of Unreal Engine 4, since Unreal Engine 5 hasn't been released yet. Also, while Epic released a trailer announcing the partnership and showcasing Unreal's 3D rendering and menu developing tools, it doesn't give us a peak at what the infotainment and instruments of the Hummer will look like. The company does tout fast boot-up times, powerful graphics, and over-the-air updates as useful features included with Unreal. But for a clear look at the final product, we'll have to wait for the October 20 reveal. Related Video:
