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.

2017 GMC Sierra 2500HD All Terrain X eyes Ram Power Wagon

If where you're going, you don't need roads, you're spoiled for choice by American automakers. Ford has the F-150 Raptor, Jeep the iconic Wrangler, and Ram offers Power Wagon. And that's just the tip of the factory off-road iceberg. General Motors is getting in on the off-roading action with the Canyon and Sierra 1500 All Terrain X. Now, the automaker is adding another notch on its belt with the Sierra 2500HD All Terrain X. On the outside, GMC continues to the all-black trend as the rest of its off-roading-oriented lineup, which includes 18-inch aluminum wheels finished in black, a bespoke grille surround, black sport bar that's mounted in the truck's bed, and four-inch side steps in black. The All Terrain X will only be offered in two colors – Black Onyx and Summer White. Those looking for more off-roading capabilities and tack the Z71 off-road suspension package as an option on the All Terrain X, adding performance Rancho shocks, Hill Descent Control, and a shield for the underbody transfer case. Two engine choices lie under this crew cab pickup's massive hood - the 6.0-liter gas V8 or the all-new Duramax 6.6-liter turbo-diesel V8. The gasoline-powered V8 continues to make 360 horsepower and 380 pound-feet of torque, while the new Duramax turbo-diesel generates 445 horsepower and 910 pound-feet of torque. While the All Terrain X may not have the same murderous look as the Ram Power Wagon, it makes off-roading a luxurious affair. And it's blacked out. The 2500HD power wagon will be on sale early next year, with a pricing announcement coming sometime in the next few months.

GM plans to sell the Chevy Tahoe and Cadillac Escalade in China

General Motors Co plans to sell full-size sport-utility vehicle (SUV) models in China for the first time, and will import a range of models to beef up its product lineup into the world's biggest car market, its China chief told Reuters. The plan would mark a change of tack for GM, which currently produces all of the vehicles it sells in China within the country, which is set to be the only major economy to grow this year amid the COVID-19 pandemic. GM, China's second-biggest foreign automaker, is aiming to offer four models as it looks to improve its brand image and support a sales recovery: Chevrolet's Tahoe and Suburban, Cadillac's Escalade and the GMC Yukon Denali. The Detroit-based company is showcasing those models at the China International Import Expo, or CIIE, an annual import show in Shanghai which started on Wednesday and runs into next week. "Our intention is to get customer reaction and find a way to sell these cars in China," said GM's China chief Julian Blissett. The automaker sees opportunities for such vehicles, partly because Chinese families are expanding, he added. "We are looking into a variety of market sales plans for these vehicles, including online sales, leasing and others," he said, declining to give a detailed timeframe for the plan. GM's Buick and Cadillac mid-size SUVs helped the group's Chinese sales grow 12% in the third quarter this year, the first quarterly growth in the past two years. But it does not have full-size SUV models, which usually have a third row of seats and has room for six or seven people. BATTLEGROUND China, where over 25 million vehicles were sold last year, is a crucial battleground for global automakers including Volkswagen AG, the biggest foreign player by sales volumes, GM and Toyota, as well as local leaders Geely and Great Wall. The country has seen auto sales pick up in recent months following a COVID-19-induced slump, and authorities say they have largely brought the epidemic under control following its emergence in the central city of Wuhan at the end of last year. The expansion plan would also mark GM's first official sales in China of GMC vehicles, a premium brand in the group. Previously GMC vehicles were only sold in the country via unofficial grey importers. The imports will, however, not change GM's basic production strategy in China. It will still mostly sell vehicles made in China - for now, at least. "Depending on however we go we might make other decisions," Blissett said.
