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.

Truck Trend names GMC Sierra Denali 2016 PTOTY

Citing its best-in-class power, its amenities, and technology, Truck Trend magazine has named the GMC Sierra Denali its 2016 Pickup Truck of the Year. Seven "all-new or significantly revised pickup trucks" were invited to compete, and out of the seven tested categories the Sierra won interior, functionality, and "Empirical," and scored second in highway testing and exterior looks. It beat the Chevrolet Silverado 1500 High Country and Colorado Z71 diesel, GMC Canyon SLT diesel, Nissan Titan XD Pro4X, Ram 1500 Rebel, and Toyota Tacoma TRD Off-Road. In the mag's 43rd annual Four-Wheeler of the Year award, the Range Rover SVR claimed the crown. The Sierra got refreshed this year with new front-end styling with HID headlamps and LED accents, tech features like Apple CarPlay, Android Auto, and wireless phone charging, and optional convenience features like a remote locking tailgate and power articulated assist steps. The big powertrain upgrade was availability of the 5.3- and 6.2-liter V8s with an eight-speed automatic transmission. This is the second time Truck Trend has conferred a PTOTY award, the Ford F-150 walking away with the silverware last year. The nod to the Sierra comes after sister publication Motor Trend named the 2016 Chevy Colorado with the Duramax diesel engine its Truck of the Year. The press release below has the details on how the accolade was won.

Meet Alex Archer, the engineer behind GM's power-sliding center console

In 2009, a GM manager complained to a 59-year-old GM technician about the hassle of retrieving items from a pickup truck bed after driving shifted the cargo. In two days, the tech had come up with the ideas that, ten years later, would debut as the MultiPro tailgate. The engineering teams kept the tailgate secret in part by hiding mock-ups in a locked storage closet in GM's Vehicle Engineering Center in Warren Michigan for two years. A piece in the Detroit Free Press reveals that another storage closet in Warren would play the same role in a different cloak-and-dagger operation, this time for the power-sliding center console in GM's new full-sized SUVs. During a meeting in early 2017, bosses gave the job of the console's creation to 24-year-old design release engineer Alex Archer, just two years out of Stanford University with a degree in engineering and product design.  This time, the catalyst for the feature was an internal GM think tank called co:lab, where employees suggest ideas. Execs gave Archer the task because "They needed someone willing to ask a lot of questions," her 36-month mandate to produce a six-way console that could be a standard cubby or a gaping maw able to swallow four gallon jugs or hide a secret compartment. Clearly, she succeeded. It took Archer and the team nine months to devise a prototype, another six months to get the green light for production. As with the tailgate, the team working on the console grew to include designers, production engineers, and suppliers. Archer, now 26, shepherded the process, and her name is on the patent. "It took a ton of people, I'm just somebody who stuck with it the whole time," she said. GM like her work well enough to produce the "Day in the Life" segment above, five months before the world would hear about the console. Archer's path to engineering was as unlikely as getting the job for the console. She had entered Stanford with plans to be a doctor. But an innovation class during her freshman year, and a sophomore summer spent helping her grandfather rebuild a 1937 MG engine recharted her course. Her grandfather told her, "You know, you could be an engineer for a car company." Consumer reaction to Archer's work won't be far off, the SUVs slated to hit dealerships soon. Meanwhile, she's busy on something that could be just as intense as the console: Restoring a 1955 Packard Clipper in her garage. Head to Freep to check out the story of Archer and the console.
