GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

Will GMC enter the subcompact crossover segment after all?

GMC last year categorically ruled out launching a subcompact crossover positioned below the Terrain, but the decade-old rumor refuses to die. The on-again, off-again model is back on track for production, according to a recent report. Citing anonymous sources, enthusiast website GM Authority claims the soft-roader is closer than ever to receiving the proverbial green light for production. It hasn't been approved yet, so development work hasn't started. What it will look like if it receives a thumbs-up from executives is up in the air, but GMC can take several paths into this lucrative (and increasingly popular) segment of America's new-car market. Chevrolet has two fighters in the ring: the Trailblazer and the Trax. GMC could feasibly choose one, put it in a brand-specific wrapper, and call it a day. It could also design its entry from scratch, though this option would take longer and cost significantly more. Either way, the model will allegedly be called Granite or Graphyte, and it will be positioned below the Terrain in terms of size and price, meaning it would likely start above $20,000. In 2019, GMC explained it ruled out expanding its range towards the bottom to position itself as a premium brand. It wanted to focus on high-profit models, like the Sierra and the Canyon, but the crossover's ever-increasing popularity may have proven too alluring to resist. Besides, small and premium aren't mutually exclusive, and downsizing would help the brand increase its annual sales. If you're experiencing deja vu, it's likely because we've heard murmurs about a city-friendly GMC since the Granite concept (pictured) made its debut during the 2010 edition of the Detroit Auto Show. It was approved for production that year, approved again in 2011 (tentatively on a Cruze platform), and abruptly canceled in 2012. GMC hasn't commented on the report, so we'll need to be patient to find out if it's accurate — and how it would differentiate its entry-level crossover from Buick's. In the meantime, the company is putting the final touches on the electric Hummer, which will be offered as a pickup and as an SUV, and it's about to unveil the 2022 Sierra.

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.
