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.

Chevy Colorado configurator goes live as GM touts fuel efficiency

While the news of today is destined to be dominated by a certain plucky Japanese roadster, props to Chevrolet and GMC for announcing its own significant bit of news about their newest pickup twins, the midsize Colorado and Canyon. The two GM-owned brands announced that the twins' 3.6-liter V6 will return up to 26 miles per gallon on the freeway.
To get such efficiency from the 305-horsepower mill, you'll need to live without four-wheel drive and be okay with a max city fuel economy of 18 mpg. The combined rating for the 2WD model sits at 21 mpg. Adding four-wheel drive drops the city and combined ratings by one mpg, while the highway rating dips from 26 to 24 mpg.
As for the twins' eagerly anticipated 2.8-liter diesel engine, it's destined for model year 2016, meaning we've got a ways to go before its efficiency and output are certified.

GMC doesn't care if it's Mt. McKinley or Denali

GMC is getting a mountain of free publicity from President Obama's decision to rename the former Mt. McKinley back to Denali in Alaska. The truck-and-SUV brand is happy to see the moniker of its high-end trim in the news, but doesn't intend to change any marketing because of the switch. "It had no impact or change on our strategy," a GMC spokesperson told the Detroit Free Press. The brand doesn't expect sales to change, though the frequent use of the word Denali in the news in a positive light amounts to free, albeit temporary, advertising for the company. Denali is the word for the nation's tallest mountain in the Koyukon Athabascan language, and it means "the high one." In 1896 a prospector rechristened the peak Mt. McKinley to support presidential candidate William McKinley. He won the election, but was assassinated in 1901. The title stuck, and the site officially got the name when a national park was created there. Since then, there has been a push to return to the original moniker, and according to the Free Press, the park became Denali in 1980. Now, the peak has followed suit. GMC started using Denali to denote the top models on the 1999 Yukon. Today, it's available as an upmarket alternative on most of the brand's lineup.
