2019 GMC Sierra 1500 pickup teased on Twitter

GM's half-ton pickup line will be fully rounded up later this week when the new GMC Sierra 1500 is revealed. Though the unveiling is on March 1, GMC has provided a teaser of the new truck ahead of time on Twitter. It shows only the front fascia, but considering the Sierra's history of simply being a badge-engineered Silverado, it's arguably the most important angle of the truck. The teaser confirms a few things we were expecting based on past spy shots. The headlights look much more conventional than the Silverado's rather small units. The Sierra's grille, unlike the Silverado's, will also rise above the tops of the headlights, providing more of a big-rig appearance. We also finally get to see the GMC badge on the front of the Sierra, and it looks like it's an enormous rendition. As for the rest of the truck, previous spy shots have shown the Sierra will have other subtle styling changes from the Silverado. The wheel wells are shaped differently, and the taillights will be unique to the GMC. The interior of the new Sierra will look almost identical to that of the Silverado, with the exception of a few minor trim details. We also expect the Sierra to use the same engine lineup as the Chevy's, which at this point we know will consist of a 3.0-liter turbocharged diesel inline-six, and naturally aspirated 5.3- and 6.2-liter V8s.

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.

GM recalling 117,000 sedans, crossovers, SUVs, pickups and vans

General Motors has issued a stop-sale to dealers and has notified the National Highway Transportation Safety Administration of its intention to recall 117,000 vehicles in the United States, Canada and Mexico. Of those vehicles, only 4,500 are at dealerships.
The affected vehicles include the Cadillac CTS and Chevrolet Impala sedans, fullsize SUVs (Cadillac Escalade, Chevy Tahoe and Suburban and GMC Yukon and Yukon XL), Lambda-platform crossovers (Chevy Traverse, Buick Enclave and GMC Acadia), heavy-duty pickups (Chevy Silverado HD and GMC Sierra HD) and fullsize vans (Chevy Express and GMC Savana). The sedans and body-on-frame SUVs include model years 2013 and 2014, while the CUVs, heavy-duty pickups and vans are limited to MY2014.
GM confirmed the recall to Autoblog via an emailed statement (which we've included below). According to the statement, the issue at hand in what is the company's 69th recall of 2014 covers the chassis-control module. Automotive News is reporting that a problem in the chassis-control system could cause a short in the module, which could cause the engine to stall or fail to start. The fault could also affect the trailer-brake control, provided it's equipped.
