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.

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC

GM can't keep up with most popular pickup orders

With the market for pickup trucks at its best since before the recession, General Motors can't afford any hiccups with the launch of its new 2014 Chevrolet Silverado and GMC Sierra twins, but it sounds like the popularity of V8-powered trucks is causing some supply-chain issues. Bloomberg reports that GM is experiencing a shortage of 5.3-liter V8 engines because an unnamed parts supplier has been unable to keep up with demand. This is leading GM to restrict the number of V8 Silverado and Sierra trucks that Chevrolet and GMC dealers are allowed to order.
Although it's unclear how long it will take to resolve the parts shortage, GM doesn't have much time to sort it out, as a new Ford F-150 looms on the horizon. At launch, GM's fullsize trucks were offered only with a base 4.3-liter V6 and the 5.3-liter V8, but a burlier 6.2-liter V8 will be available soon. Interestingly, at least at the moment, GM truck buyers don't seem as willing to downsize to V6 power as buyers of the F-150, which gets some 42-percent of its sales from trucks equipped with its EcoBoost V6 engine (not including the normally aspirated base V6).
Working out the kinks in the Silverado and Sierra's supply chain couldn't be more important to the health of the company. Full-size pickups are a huge profit driver - in 2012, the trucks were said to make up about two-third of GM's total profits.
