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 recalls full-size truck, SUVs and vans over faulty shifter mechanism

Twelve different General Motors vehicles from the 2013 model year, up to 54,686 units in total, are being recalled over two potential issues with their steering columns. The models in question, all full-size trucks, SUVs or vans, are the: Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Express, Silverado, Suburban, Tahoe, and GMC Savana, Sierra, Yukon and Yukon XL.
The affected vehicles were built with a fractured parking lock cable or "a malformed steering column lock actuator gear in the lock module assembly." As a consequence, they could shift out of park without the brake pedal being applied or with the key removed or in the off position.
A bulletin from the National Highway Traffic Safety Administration indicates that the recall should begin on January 17. GM will notify owners, at which time they can take their vehicles to their dealers for repair free of charge. Have a look at the bulletin below for more information.

2021 GMC Canyon AT4 Road Test | The everyday tool

Bold take: The GMC Canyon is the most well-rounded midsize truck. Admittedly, “well-rounded” is a lukewarm compliment, but the Canyon does nearly everything well. It is not the flashiest, which is undeniably the Jeep Gladiator. Or the most comfortable, which is the Honda Ridgeline. But for those seeking a midsize truck that looks like a truck, drives like a truck and has a solid interior, the Canyon is the right formula. We would test the 2021 GMC Canyon AT4 for a week and find that itÂ’s pleasant, capable and sturdy off-road. We would haul a bookshelf in the bed, get dirty during a woodsy soft-road jaunt and pile up the miles running around town. In short, itÂ’s exactly what most need in a midsize truck.  The AT4 model is new for 2021, and it replaces the All-Terrain model, a move GMC is rolling out across its lineup. The AT4 adds an off-road-tuned suspension with hill-descent control, beefy 31-inch Goodyear Wrangler DuraTrac tires wrapped around 17-inch aluminum wheels, standard four-wheel drive with locking rear differential and a transfer case skid plate. The AT4 punches up the CanyonÂ’s appearance with red tow hooks, dark chrome elements and a bigger grille thatÂ’s similar to the SierraÂ’s. The Canyon Denali, which was also refreshed for ‘21, is showier, but the AT4 trim feels cooler with its understated off-road vibes. Considering this, we head out for an afternoon drive along a familiar route through DetroitÂ’s northern suburbs. The Canyon is a solid daily driver. The 3.6-liter V6 rated at 308 horsepower and 275 pound-feet of torque is widely used in General Motors vehicles. ItÂ’s powerful and actually sounds pretty good — even throaty — in GMCÂ’s midsize truck. Our passengers are surprised to be pulled back in their seats during hard acceleration, and the eight-speed automatic transmission is well-calibrated for the many jobs the Canyon is called upon to perform. This powertrain, standard in the AT4 and Denali trims, is a step up from the 2.5-liter inline-four and six-speed auto offered on the lower models. ItÂ’s worth it. The 2.8-liter Duramax diesel is an option on higher-spec Canyons, and its 369 lb-ft of torque is tantalizing. For everyday use, take the V6. Our tester with the gasoline V6 and four-wheel drive can tow as much as 7,000 pounds, has a maximum payload of 1,609 pounds and has respectable fuel economy of 17 mpg in the city and 24 mpg on the highway.
