The GMC Hummer EV is big and fast; it's also a social conundrum

Pedestrian fatalities, unresolved safety issues, overachieving and overweight trucks — overweight electric trucks — and divisive attitudes about vehicles equipped as is the new Hummer EV, are very much on the mind of Robinson Meyer. Mr. Meyer, who suggests that the 1,000-horsepower pickup is a cross "between an ambulance and a race car," is a staff writer for The Atlantic, a well-respected, long-lived journal founded in 1857. His recent essay in the monthly's flagship magazine starts off describing a scary video clip posted online by Edward Barseghian that features the 9,000-pound Hummer hurtling full tilt towards three lanes of cars idling at a light (the driver stops it in time). Then he goes on to pretty much berate the machine. "The Hummer EV haters and lovers had discovered one of the most important facts about electric 'super trucks': They are very heavy, and they go very fast," he writes. "If you imagine an ambulance that can accelerate as fast as a Formula 1 car, youÂ’re imagining a vehicle only slightly more unwieldy than the new Hummer." Meyer goes on to discuss the issue of allowing battery powered vehicles that weigh as much as the Hummer does onto public roads. "The weight of EVs is a safety issue that drivers — and cyclists and pedestrians — will only have to keep worrying about as these cars go mainstream," he explains. "Suffice it to say that cars as huge as the Hummer EV need to face some kind of regulation, especially in cities and towns, where they pose a distinct threat to the public." To Hummer devotees, them's fightin' words. But Meyer takes pains to present a sort of response from Anthony Schiavo, a research director at Lux Research, a global advisory firm: Why is the Hummer so heavy if its batteries weigh only about 3,000 pounds? “ItÂ’s absolutely a design choice and a marketing choice,” Schiavo answers. “People like larger vehicles, and the reason why those larger vehicles are getting made is because they sell.” The author concludes by bringing into his thesis the issues of climate change, liberal and conservative politics. In some places, his arguments wander; they become muddled. But for those enthused about electrics and big trucks, "Frankenstein's Hummer" is worth a read.

GMC Canyon AT4 OVRLANDX concept previews potential Bison-like model

GMC is signaling a move into serious off-road territory with this Canyon AT4 OVRLANDX concept. As its name suggest, this one-off was put together as a demonstration of what an overland-style GMC midsizer could potentially look like, but a glance beneath the surface reveals the bones of what we expect to be the forthcoming Canyon AT4X.  While "AT4" has been trickling down through the GMC lineup for the past few model years, AT4X kicks the basic off-road formula up a notch, a la Chevrolet's Colorado ZR2, which gains extra underbody protection, locking front and rear differentials and Multimatic's phenomenal DSSV dampers.  GMC Canyon AT4 OVRLANDX Off-Road Concept View 23 Photos OVRLANDX takes that to the next level, borrowing (and building upon) cues from the even-more-rugged ZR2 Bison, including rocker panel guards, cast-iron control arms, a custom front bumper with an integrated winch, built-in front recovery points, wheel arch trim with integrated LED task lighting, and guy lines for protecting the windshield from low-hanging branches. The custom rear bumper is even from American Expedition Vehicles (AEV), with whom Chevy partnered to produce the Bison's unique exterior bits. Does that seem like a wink and nod to you? “We wanted to showcase GMC Canyon with this concept and punctuate GMCÂ’s commitment to premium, off-road capable vehicles,” said Buick & GMC Global Vice President Duncan Aldred. "Consumer reaction to this conceptÂ’s design will help us further serve the growing market of buyers leading authentic outdoor lifestyles." This content is hosted by a third party.

In a way, the roof-mounted tent, awning, cooler and kitchenette are just there to disguise the fact that GMC will likely build a production pickup with much these same specs when the new model debuts for the 2023 or 2024 model year – or perhaps even sooner. While this concept is built around GM's existing 3.6-liter V6 powertrain, the redesigned Canyon is expected to be offered with just one engine: a 2.7-liter turbocharged four-cylinder lifted from the Silverado and Sierra pickups.  Rumors have pointed to a GMC variant of the Colorado ZR2 since the midsize pickup adopted the AT4 branding for its off-road variant.

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.
