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.

GM delays truck plant shift so workers can watch Detroit Lions NFC Championship game

It would be difficult to overstate just how big of a deal it is for the city of Detroit and its residents (and residents of southeast Michigan in general) that the Detroit Lions not only made it convincingly into the NFL playoffs but found significant success in defeating the Los Angeles Rams in the Wildcard round and then the Tampa Bay Buccaneers the following week. But if there's one thing we can point to as an automotive-minded group, it's this: General Motors has delayed the start of the third shift at its Flint Assembly plant so that workers won't have to miss any part of the game. To emphasize the magnitude of this decision, it's important to note that the Chevrolet Silverado HD and GMC Sierra HD are built at the plant, and the popularity and, perhaps more importantly, profitability of those heavy duty trucks is so high that it's the only GM plant in Michigan that runs a third shift, as pointed out by the Detroit Free Press. The delay is roughly an hour in total, and workers won't be paid for that missing time. We doubt there will be any complaints. Granted, this isn't the first time GM has delayed starting a late shift due to a big sporting event. In prior years, delays have been recorded for some Super Bowls and for the in-state Michigan vs. Michigan State rivalry game at GM facilities in Lansing, Michigan. Still, GM's statement on why it would hold off production of such a lucrative pair of vehicles explains it better than we can: "We recognize the Detroit Lions playing in the NFC Championship game as a rare, unique opportunity that warrants this temporary schedule adjustment to allow employees to enjoy the game and make it to work on time." It's not GM's only show of Lions pride. Take a close look at the General Motors logo currently being displayed at the Renaissance Center, GM's headquarters in Detroit. General Motors is displaying its Motor City pride with a subtle logo redesign to honor the Detroit Lions as they continues their Super Bowl hunt.

Ford has yet to provide a comment, but Stellantis, makers of the Ram truck and Jeep SUVs, has confirmed it will be running normal schedules at all of its facilities. For now, there's only one more question that needs answering: What if the game goes to overtime?

2019 GMC Yukon Graphite Edition offers Denali engine and features without the chrome

A sporty-looking option package called RST was recently introduced for the Chevy Tahoe and Suburban that also offered the option of a 6.2-liter V8 and magnetic suspension. Now GMC is getting in on the action with the GMC Yukon and Yukon XL Graphite Edition. The trim package adds a number of visual enhancements, and, if you're so inclined, has a performance version with the same 6.2-liter V8 and magnetic suspension as the Tahoe RST and Yukon Denali. As for appearances, the Graphite Edition adds black trim almost everywhere, including the roof rails, grille, fog light surrounds, and window surrounds. It also adds 22-inch wheels, regardless of whether it's just the appearance version or the performance version. The appearance package has machined-finish wheels, and the performance package has black painted wheels. As previously mentioned, the performance version of the Graphite Edition adds magnetic suspension and the 6.2-liter V8 with 420 horsepower and 460 pound-feet of torque found on the Denali and the Tahoe and Suburban RSTs. It's coupled to a 10-speed automatic transmission, and gets a rear axle ratio of 3.23:1. It also gets a few other Denali features such as a color heads-up display, Bose noise cancellation, a 170-amp alternator, and a trailer brake controller. The Graphite Edition can be had with both two-wheel drive or four-wheel drive. The Graphite Edition can only be had on Yukon and Yukon XL SLT models. Pricing hasn't been announced yet, but it's likely it will be a bit more affordable than buying a Denali model.
