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.

Recon Power Bikes partners with GMC on AWD Hummer eBike

Want the ultimate two-wheeled companion to your new GMC Hummer EV, or maybe you just want something electric and all-wheel drive without the Hummer's price tag? Recon Power Bikes has you covered with its new Hummer EV e-bike. Not convinced? Well, hear the specs before you bail. You might be surprised.  Recon's new offering is marketed as "all-wheel drive," which our resident two-wheeled expert and consumer guru Jeremy Korzeniewski tells us is quickly becoming conventional nomenclature for dual-motor electric bicycles. Hey, if you've got two wheels and both have motors, it's technically correct, even if it sounds a bit silly to those of us who prefer the comforts of a cage and four wheels on pavement.  Each of the two motors produces 750 watts, which combines for just a little over 2 (two!) horsepower, but remember, this is a bicycle, not a sport bike. And flipping the coin, that lone pony is accompanied by more than 118 pound-feet (or roughly a 1.8-liter Miata's worth) of torque. Recon says its top speed is north of 28 mph, which is plenty quick for something that you might see strapped to the same hitching post as a 30-year-old Huffy. The base battery offers 17.5 aH of capacity; an upgrade bumps that to 21. Recon says the total range should fall between 40 and 50 miles. The package is rounded out by an adjustable front suspension, four-piston hydraulic brakes, puncture-resistant 4-inch all-terrain tires with molded-in liners and Shimano gearing.  Recon says the Hummer e-bike offers "on-demand" AWD (rear by default; both when called upon) and even offers three fixed drive modes — "Cruise" (rear wheel drive, for maximum range and efficiency), "Traction" (front wheel drive, for navigating with low grip) and "Adrenaline" (for "off road all wheel drive dominance of the toughest, steepest terrain"). "Adrenaline" mode even offers real-time torque vectoring, just like a real Hummer EV. The two vehicles are basically the same, only the bike weighs just 96 pounds, not more than 9,000.  Look for the Recon Power Bikes GMC Hummer e-bike to hit the market in early December with a starting price of $3,999. That may sound steep, but keep in mind that QuietKat's Jeep eBike costs nearly double that.  Related video: This content is hosted by a third party.

GM recalls 638,000 U.S. SUVs, trucks for unintended braking

WASHINGTON — General Motors is recalling 638,000 U.S. sport utility vehicles and pickup trucks because a wheel-speed sensor could fail and cause unintended braking, it said Thursday. The recall covers 2015-2020 Chevrolet Suburban, Tahoe, and Yukon and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. The sensor failure could result in unintended activation of the driveline protection system, and cause unintended braking of the wheel on the opposite side of the failed sensor. That could cause the vehicle to pull to one side unexpectedly, increasing the risk of a crash, the Detroit automaker said. GM said it was not aware of any crashes relating to the issue but found 150 field claims alleging the condition caused unintended braking or lateral vehicle motion. A GM dealer in May submitted a warranty report relating to the issue in a 2018 GMC Yukon, and two days later, a GM brand quality manager submitted the report to GMÂ’s Speak Up For Safety program that tracks potential safety issues, which prompted a GM investigation and testing.
