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.

The UAW's 'record contract' hinges on pensions, battery plants

DETROIT - After nearly four weeks of disruptive strikes and hard bargaining, the United Auto Workers and the Detroit Three automakers have edged closer to a deal that could offer record-setting wage gains for nearly 150,000 U.S. workers. General Motors, Ford Motor and Chrysler parent Stellantis have all agreed to raise base wages by between 20% and 23% over a four-year deal, according to union and company statements. Ford and Stellantis have agreed to reinstate cost-of-living adjustments, or COLA. The companies have offered to boost pay for temporary workers and give them a faster path to full-time, full-wage status. All three have proposed slashing the time it takes a new hire to get to the top UAW pay rate. The progress in contract talks follows the first-ever simultaneous strike by the UAW against Detroit's Big Three automakers. The union began the strike on Sept. 15 in hopes of forcing a better deal from each major automaker. But coming close to a deal is not the same thing as reaching a deal. Big obstacles remain on at least two major UAW demands: restoring the retirement security provided by pre-2007 defined benefit pension plans, and covering present and future joint- venture electric vehicle battery plants under the union's master contracts with the automakers. On retirement, none of the automakers has agreed to restore pre-2007 defined-benefit pension plans for workers hired after 2007. Doing so could force the automakers to again burden their balance sheets with multibillion-dollar liabilities. GM and the former Chrysler unloaded most of those liabilities in their 2009 bankruptcies. The union and automakers have explored an approach to providing more income security by offering annuities as an investment option in their company-sponsored 401(k) savings plans, people familiar with the discussions said. Stellantis referred to an annuity option as part of a more generous 401(k) proposal on Sept. 22. Annuities or similar instruments could give UAW retirees assurance of fixed, predictable payouts less dependent on stock market ups and downs, experts said. Recent changes in federal law have removed obstacles to including annuities as a feature of corporate 401(k) plans, said Olivia Mitchell, a professor at the University of Pennsylvania Wharton School and an expert on pensions and retirement. "Retirees want a way to be assured they won't run out of money," Mitchell said.

2021 GMC Sierra 1500 Review | More towing, same truck

The 2021 GMC Sierra 1500 and the Chevrolet Silverado 1500 are close siblings, and they’re getting closer every year. One of the SierraÂ’s previous standout features, the Multi-Pro tailgate, can now be found on the Silverado for 2021, providing even fewer reasons to choose the GMC instead of the Chevy. Really, if youÂ’re looking at the more modest SLE and SLT models, the choice between the two largely depends on styling preference. The Sierra Denali is a slightly different story, as its available adaptive suspension is exclusive to GMC and notably improves both the ride and handling.  Of course, it still can't match the Ram 1500 in either regard, plus the Denali cabin continues to be a rather half-hearted attempt at luxury. Especially considering the genuinely high-lux offerings of Ram and Ford. The gap isn't so huge between the Sierra's lower trim levels and its non-Chevy competitors, but the cabin's design, quality and functionality still leave something to be desired. True, that often isn't a priority for truck buyers, but the Sierra isn't superior in enough other ways to balance it out. It's a capable truck with a compelling variety of powertrains, but it generally just doesn't go that extra mile beyond the competition as well as its Silverado sibling. What's new for 2021? Changes for 2021 are mostly equipment-related, but there were some vital towing and pricing changes made for the new year, too. All 2021 Sierra 1500s come with a suite of new towing tech detailed here. New technologies include a trailer length indicator, jack-knife alert, trailer backup guidelines, and camera enhancements that include a rear side view and cargo bed view. GMC expanded availability of the Multi-Pro tailgate, now allowing folks who opt for the lower SLE and Elevation trims to option it. The AT4 adds new Goodyear Wrangler Territory all-terrain tires and an off-road high-clearance step. Diesel buyers will be delighted to hear that GMC has lowered the price by $1,500 to $995, and raised the trailering capacity by 1,900 pounds to a more competitive 9,300. Maximum towing for the 2.7-liter turbo-four-cylinder is also up by 2,300 pounds to 9,200 pounds. GMC says the increase for the diesel is due to “better-than-expected rear axle durability,” and the four-cylinder is up because GM found the engine possesses “better-than-expected cooling performance.” What's the interior and in-car technology like?
