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.

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.

Mercedes moves R-Class production to AM General in Indiana

Go back a decade or two and you'd have seen the SUV market polarizing in opposite directions: hard-core off-roaders like the Hummer on the one hand, and passenger-focused crossovers like the Mercedes R-Class on the other. Now their fates are set to intertwine, at least as far as manufacturing is concerned. No longer producing Hummers, AM General (which designed and originally produced the Hummer) has been assigned the task of manufacturing the R-Class at its underused, 675,000 square-foot Commercial Assembly Plant in Mishawaka, IN – part of metropolitan South Bend. The decision was undertaken to allow Mercedes to free up production capacity at its plant in Tuscaloosa, AL, where it also produces the M-Class, GL-Class and C-Class, and where it will soon begin manufacturing the GLE Coupe. The vacation of the R-Class assembly line could be earmarked to make room for that new slant-roofed crossover (which was originally thought to be joining the Tuscaloosa plant as a fifth model) or could pave the way for another model to reach Alabama altogether. The multi-year arrangement to manufacture the R-Class makes AM General the first manufacturer contracted to build Mercedes-Benz vehicles in the US, but hardly the only one in the world. The G-Class – which could, incidentally, be characterized as the German equivalent of the Hummer – is built on Mercedes' behalf by Magna Steyr in Austria, and the company builds many of its passenger and commercial vehicles for local consumption under joint ventures in the Far East especially. The R-Class was first introduced in 2005, and though it's still built in America, it was removed from the company's US lineup back in 2012. However Mercedes confirms that, since 2013, it has been and remains available exclusively in China. That puts the R-Class in the rare position of being manufactured in the United States by (or now for) a foreign automaker but unavailable for sale here. AM General Selected As Mercedes-Benz First and Only Contract Manufacturer of Vehicles in the United States SOUTH BEND, Ind., Jan. 27, 2015 /PRNewswire/ -- AM General LLC and Mercedes-Benz U.S. International, Inc., today announced that Mercedes-Benz has selected AM General to manufacture the Mercedes-Benz R-Class luxury vehicle at AM General's world-class 675,000 square-foot Commercial Assembly Plant.
