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 recall woes continue with 662,000 pickups trucks and Cruze sedans

General Motors can't seem to get its name out of the "bad news" column. Two more recalls were announced late Friday evening that will see The General calling in 490,200 fullsize pickup trucks and SUVs, along with 172,000 Chevrolet Cruze models.
For those keeping track, General Motors has issued recalls for an alarming 4.8 million vehicles so far since last month.
The Chevy Silverado 1500, Tahoe and Suburban, GMC Sierra 1500 and Yukon models from the 2014 and 2015 model years are being recalled for a flaw in their transmissions wherein loose oil cooler lines may cause a fire. The automaker said in a statement (see below) that it knows of three incidents of loose transmission lines causing problems, but no injuries. We can't confirm whether it was this transmission issue that caused the widely publicized blaze that consumed a 2015 GMC Yukon that was being test driven in California.

GM updating fullsize pickups for 2015

As Ford prepares to hit the market with its x-factor, aluminum-intensive F-150 and Ram sales stand tall enough to meet General Motors truck sales eye-to-eye, GM is putting the word out that it's going to add more features to its trucks and do so more regularly. An executive engineer for pickups told reporters that "a whole array" of changes are on the way as soon as the 2015 model year and then would likely come "the year after that, the year after that, the year after that."
Only GM knows the way it plans to go with its fullsize trucks, with almost everyone else - including its dealers - griping about market share at the same time as they applaud profits and hope for clarity and growth. GM raised prices on the Chevrolet Silverado and GMC Sierra not long after launch even as it was losing market share and getting called "the least successful large pickup launch over the last 15 years," further upsetting dealers, then Ram outsold the Silverado in March of this year and led GM to increase incentives. But transaction prices rose with the premium; in the first quarter of this year more than 37 percent of the trucks costing more than $40,000 were the Silverado and Sierra, leading one dealer to say of the Sierra, "You can't sell a cheap one," and the analyst who made that "least successful launch" comment to opine, "GM may have made the right call to go for price over share."
We won't know for a few months what any of these updates will be, but the rumored changes for the Silverado and Sierra appear to cover all the bases, including appearance, capability and fuel economy. Rumors run to higher gear counts, stop-start technology and diesel engines before brand-new pickups come for the 2019 model year, those next-generation models supposedly to be engineered with a lot more aluminum.
