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.

GM recalls nearly 1 million vehicles for airbag defect

WASHINGTON — General Motors said on Friday it will recall nearly 1 million sport utility vehicles in the United States because the driver's airbag inflator may explode during deployment. The recall covers 994,763 Buick Enclave, Chevrolet Traverse, and GMC Acadia vehicles from the 2014 through 2017 model years with modules produced by ARC Automotive Inc. Dealers will replace the driver's airbag module. The National Highway Traffic Safety Administration said a driver in Michigan of a 2017 Chevrolet Traverse was in a crash in which the front-driver airbag inflator ruptured during deployment causing facial injuries. An April 25 inspection confirmed that the front driver airbag inflator ruptured in the vehicle. The National Highway Traffic Safety Administration (NHTSA) demanded the recall of 67 million air bag inflators because it believes there is a safety defect, but auto supplier ARC Automotive Inc rejected the U.S. regulator's request, documents released on Friday show. The auto safety agency said the inflators pose an unreasonable risk of death or injury. Even as ruptures mount, "ARC has not made a defect determination that would require a recall of this population," NHTSA said in its demand letter to the Tennessee-based company. "Air bag inflators that project metal fragments into vehicle occupants, rather than properly inflating the attached air bag, create an unreasonable risk of death and injury." GM said it was still investigating the issue with the assistance of a third-party engineering firm. "GM is taking this expanded field action out of an abundance of caution and with the safety of our customers as our highest priority," the Detroit automaker said. GM said it was aware of two prior ruptures of ARC-manufactured airbag inflators in 2015 Chevrolet Traverse vehicles, and GM conducted two earlier small recalls of about 3,000 ARC inflators. All three rupture events in Chevrolet Traverse vehicles involved the same inflator variant. ARC noted in a letter made public Friday that no root cause for those ruptures has been identified by ARC or GM. ARC said it was assessing the scope of GMÂ’s recall.  Government/Legal Recalls Buick Chevrolet GMC Safety Crossover SUV
