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.

Are orphan cars better deals?

Most folks don't know a Saturn Aura from an Oldsmobile Aurora. Those of you who are immersed in the labyrinth of automobilia know that both cars were testaments to the mediocrity that was pre-bankruptcy General Motors, and that both brands are now long gone. But everybody else? Not so much. By the same token, there are some excellent cars and trucks that don't raise an eyebrow simply because they were sold under brands that are no longer being marketed. Orphan brands no longer get any marketing love, and because of that they can be alarmingly cheap. Case in point, take a look at how a 2010 Saturn Outlook compares with its siblings, the GMC Acadia and Buick Enclave. According to the Manheim Market Report, the Saturn will sell at a wholesale auto auction for around $3,500 less than the comparably equipped Buick or GMC. Part of the reason for this price gap is that most large independent dealerships, such as Carmax, make it a point to avoid buying cars with orphaned badges. Right now if you go to Carmax's site, you'll find that there are more models from Toyota's Scion sub-brand than Mercury, Saab, Pontiac, Hummer, and Saturn combined. This despite the fact that these brands collectively sold in the millions over the last ten years while Scion has rarely been able to realize a six-figure annual sales figure for most of its history. That is the brutal truth of today's car market. When the chips are down, used-car shoppers are nearly as conservative as their new-car-buying counterparts. Unfamiliarity breeds contempt. Contempt leads to fear. Fear leads to anger, and pretty soon you wind up with an older, beat-up Mazda MX-5 in your driveway instead of looking up a newer Pontiac Solstice or Saturn Sky. There are tons of other reasons why orphan cars have trouble selling in today's market. Worries about the cost of repair and the availability of parts hang over the industry's lost toys like a cloud of dust over Pigpen. Yet any common diagnostic repair database, such as Alldata, will have a complete framework for your car's repair and maintenance, and everyone from junkyards to auto parts stores to eBay and Amazon stock tens of thousands of parts. This makes some orphan cars mindblowingly awesome deals if you're willing to shop in the bargain bins of the used-car market. Consider a Suzuki Kizashi with a manual transmission. No, really.

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.
