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.

2016 GMC Sierra All Terrain X is cool but no Raptor threat

If you want a brutish off-roader from Ford or Fiat Chrysler Automobiles, you're spoiled for choice. There's the F-150 SVT Raptor, the Jeep Wrangler, and the Ram Rebel and Power Wagon. But since General Motors killed the Hummer brand, it's been without any real competitor to those trucks. The new, special edition GMC Sierra All Terrain X is not going to be that vehicle, but it's close enough to be worth a look. The oft-overlooked Sierra All Terrain's off-road suspension and Eaton locking rear differential give it some real trail credentials. The All Terrain X builds on both with cosmetic and performance upgrades. For most owners, the big draw will be the brawnier 5.3-liter V8. Fitted with a performance exhaust, it should deliver a meatier tone, and according to GMC it bumps output up from 355 to 365 horsepower. The other big performance upgrade comes from the tires, knobby Goodyear Wrangler DuraTrac MT mud-terrain-rated things. The tires and their accompanying 18-inch black aluminum wheels are nice touches. Cool as the All Terrain X might be, it strikes us as an odd strategy for the GMC brand. For one, the trail-ready tires and performance exhaust of the All Terrain X don't seem to fit into the more premium market position that GMC occupies. Moreover, Chevy already has an off-road-oriented pickup in the new Colorado Z71 Trail Boss. Visual upgrades like the black bed-mounted sport bar, LED off-road lights, blacked-out accents, and the 18-inch wheels, the look of the All Terrain X is more in line with the Colorado Trail Boss theme. It's just our two cents, but it seems like attaching the All Terrain X's aesthetic to the Silverado would have been a stronger strategy, and would give Colorado buyers a larger off-road-focused truck to aspire to. You can look for the special edition All Terrain X in GMC dealers this spring, with prices to be announced closer to the on-sale date. Read on for the official press release from GMC.

GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.
