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.

Big electric trucks won't save the planet, says the NYT

When The New York Times decides that an issue is an issue, be prepared to read about it at length. Rarely will a week passes these days when the esteemed news organization doesn’t examine the realities, myths and alleged benefits and drawbacks of electric vehicles, and even The Atlantic joins in sometimes. That revolution, marked by changes in manufacturing, consumer habits and social “consciousness,” may in fact be upon us. Or it may not. Nonetheless, the newspaper appears committed to presenting to the public these pros and cons. In this recently published article titled, “Just How Good for the Planet Is That Big Electric Pickup Truck?”—wow, thatÂ’s a mouthful — the Times focuses on the “bigness” of the current and pending crop of EVs, and how that impacts or will impact the environment and road safety. This is not what news organizations these days are fond of calling “breaking news.” In October, we pointed to an essay in The Atlantic that covered pretty much the same ground, and focused on the Hummer as one particular villain, In the paper and online on Feb. 18, the Times' Elana Shao observes how “swapping a gas pickup truck for a similar electric one can produce significant emissions savings.” She goes on: “Take the Ford F-150 pickup truck compared with the electric F-150 Lightning. The electric versions are responsible for up to 50 percent less greenhouse gas emissions per mile.” But she right away flips the argument, noting the heavier electric pickup trucks “often require bigger batteries and more electricity to charge, so they end up being responsible for more emissions than other smaller EVs. Taking into consideration the life cycle emissions per mile, they end up just as polluting as some smaller gas-burning cars.” Certainly, itÂ’s been drummed into our heads that electric cars donÂ’t run on air and water but on electricity that costs money, and that the public will be dealing with “the shift toward electric SUVs, pickup trucks and crossover vehicles, with some analysts estimating that SUVs, pickup trucks and vans could make up 78 percent of vehicle sales by 2025." No-brainer alert: Big vehicles cost more to charge. And then thereÂ’s the safety question, which was cogently addressed in the Atlantic story. Here Shao reiterates data documenting the increased risks of injuries and deaths caused by larger, heavier vehicles.

IIHS: High numbers of drivers treat partially automated cars as fully self-driving

WASHINGTON — Drivers using advanced driver assistance systems like Tesla Autopilot or General Motors Super Cruise often treat their vehicles as fully self-driving despite warnings, a new study has found. The Insurance Institute for Highway Safety (IIHS), an industry funded group that prods automakers to make safer vehicles, said on Tuesday a survey found regular users of Super Cruise, Nissan/Infiniti ProPILOT Assist and Tesla Autopilot "said they were more likely to perform non-driving-related activities like eating or texting while using their partial automation systems than while driving unassisted." The IIHS study of 600 active users found 53% of Super Cruise, 42% of Autopilot and 12% of ProPILOT Assist owners "said that they were comfortable treating their vehicles as fully self-driving." About 40% of users of Autopilot and Super Cruise — two systems with lockout features for failing to pay attention — reported systems had at some point switched off while they were driving and would not reactivate. "The big-picture message here is that the early adopters of these systems still have a poor understanding of the technologyÂ’s limits," said IIHS President David Harkey. The study comes as the National Highway Traffic Safety Administration (NHTSA) is scrutinizing Autopilot crashes. Since 2016, the NHTSA has opened 37 special investigations involving 18 deaths in crashes involving Tesla vehicles and where systems like Autopilot were suspected of use. Tesla did not respond to requests for comment. Tesla says Autopilot does not make vehicles autonomous and is intended for use with a fully attentive driver who is prepared to take over. GM, which in August said owners could use Super Cruise on 400,000 miles (643,740 km) of North American roads and plans to offer Super Cruise on 22 models by the end of 2023, did not immediately comment. IIHS said advertisements for Super Cruise focus on hands-free capabilities while Autopilot evokes the name used in passenger airplanes and "implies TeslaÂ’s system is more capable than it really is." IIHS in contrast noted ProPILOT Assist "suggests that itÂ’s an assistance feature, rather than a replacement for the driver." NHTSA and automakers say none of the systems make vehicles autonomous. Nissan said its name "is clearly communicating ProPILOT Assist as a system to aid the driver, and it requires hands-on operation.
