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 renames its Detroit-Hamtramck plant Factory Zero

Maybe we'll win, saved by zero. General Motors on Friday announced that its sprawling Detroit-Hamtramck facility, which is being retooled to build electric vehicles, has been renamed Factory Zero — as in zero emissions, along with the promise of an autonomous future in which there are zero crashes and zero congestion. The company is spending $2.2 billion to retool the plant into a futuristic facility that is flexible enough to build a variety of cars and trucks across the GM portfolio of brands. GM says that's the most it has ever spent on a production facility, and when the plant's cranking out EVs at scale it will have created 2,200 manufacturing jobs. Factory Zero's first projects will be the all-electric GMC Hummer pickup and the self-driving electric Cruise Origin, both build on GM's new Ultium battery platform, with other EVs to follow. Factory Zero should start cranking out Hummer pickups by fall 2021. A Hummer SUV will come along later. Check back with Autoblog when the Hummer is revealed next Tuesday, Oct. 20. Sustainability will be another key feature. During construction, excess concrete from pours in the plant has been used to pave roads, and stormwater runoff is being recycled to charge the factory suppression system and circulate in cooling towers. The 365-acre site also has 16.5 acres of wildlife habitat — GM says monarch butterflies hang out there, along with foxes and wild turkeys. GM says it's committed to powering all its southeast Michigan plants with sustainable energy by 2023, the rest of its U.S. facilities by 2030, and overseas plants by 2040. To that end, Factory Zero has a 30-kilowatt solar carport, and a 516-kilowatt ground-mounted solar farm, from DTE. “Factory ZERO is the next battleground in the EV race and will be GMÂ’s flagship assembly plant in our journey to an all-electric future,” said Gerald Johnson, GM executive vice president of Global Manufacturing. “The electric trucks and SUVs that will be built here will help transform GM and the automotive industry.” Related Video:     Green Hirings/Firings/Layoffs Plants/Manufacturing GM Hummer hamtramck

Why didn't GM recall fire-prone Hummers earlier?

As early as 2009, motorists reported fires in the Hummer H3. In a complaint filed that March with the regulatory agency in charge of vehicle safety, one motorist said they leaped into a smoldering vehicle and drove it away from gas pumps moments before it was engulfed in flames. Three months later, another motorist described how a fire spread from behind the glove box and consumed their H3. Dozens of car owners filed similar complaints with the National Highway Traffic Safety Administration in the six years that followed, detailing car fires of varying severity that originated in the HVAC systems of their Hummer H3s. But General Motors didn't issue a recall for any of the affected cars until last week, prompting fresh questions about how the company treats safety concerns in the wake of an ignition-switch flaw that went unaddressed for years and, at latest count, is responsible for killing at least 124 motorists. In recall documents filed with NHTSA last week, GM initially said it knew of three fires associated with the defect. Within hours, the company said it knew of 42 fires associated with the problem and three injuries sustained by vehicle occupants. A company spokesperson attributed the inconsistency to a "misstated" number in the original documents and that the higher number comes from NHTSA complaints, reports to GM and TREAD data. Beyond that discrepancy, the documents show General Motors, which has touted a revitalized attitude toward safety concerns since the ignition-switch recalls, did nothing upon determining there was a problem with the H3s. Prompted by two complaints the company received in September 2014, General Motors says it launched an internal investigation related to melting blowers in the HVAC system on December 8, 2014. In that investigation, the company says it confirmed a problem existed, finding that "mismatched electrical conductivity could result in overheating and melting of the blower motor connector module." But even with that conclusion, the company opted to close its internal investigation on April 29, 2015, without taking any action. It wasn't until NHTSA officials met with GM representatives in a meeting on June 18, 2015, that General Motors was prompted to reconsider.
