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 and Isuzu to partner for medium-duty commercial truck

General Motors is returning to the medium-duty truck business in the US for the first time since 2009 thanks to a new deal with longtime-partner Isuzu. The arrangement brings the Isuzu N-series models to Chevrolet dealers with the Bowtie's branding on them in 2016. There are six medium-duty Chevy models arriving at dealers in regular cab and crew cab bodies: the 3500, 3500HD, 4500, 4500HD, 5500, and 5500HD. The trucks will be sold as a bare chassis for buyers to outfit to their needs. Depending on model, customers will have the choice of an Isuzu-sourced 3.0-liter and 5.2-liter diesel engines or a 6.0-liter V8 gasoline-fueled engine from GM and six-speed gearbox. According to company spokesperson Bob Wheeler to Autoblog, the diesel models will be built in Japan and the rest assembled from knockdown kits in Charlotte, MI. This kind of vehicle sharing isn't uncommon for GM in the commercial segment, and it already partners with Nissan to use the Japanese brand's NV200 as the City Express van. The General also once owned a significant stake in Isuzu, and the two have remained collaborators even since then. Isuzu and GM Enter Commercial Vehicle Collaboration Agreement in the U.S. 2015-06-15 DETROIT and FUJISAWA, Japan – General Motors Co. (NYSE: GM) and Isuzu Motors (TSE 7202) have reached an agreement on a U.S. commercial vehicle collaboration, allowing Isuzu to strengthen its product lineup and GM to expand its commercial vehicle portfolio.

To strengthen the product lineup, GM and Isuzu will explore the use of GM commercial vehicle components for Isuzu low cab forward trucks and GM will continue to produce and supply the 6.0L V-8 gas engine and six-speed transmission for Isuzu gasoline-powered low cab forward trucks. Isuzu and GM have maintained a strategic partnership for more than 40 years, producing collaborative business opportunities throughout the world.

GM dealers unhappy about pickup prices

The backlash is beginning. Following General Motors' price hike of the Chevrolet Silverado and GMC Sierra last week, dealers across the country are expressing their ire over increasing prices in the face of rebates and discounts on trucks from Ford and Ram.
Speaking to Automotive News, Sam Pilato, the general manager at Dimmitt Chevrolet in Clearwater, FL, Silverados are "selling very poorly." W. Carrol Smith, the president of Monument Chevrolet in the heart of truck country, Texas, said, "[GM's] position is that the vehicle stands on its own and it doesn't need a bigger rebate. That's not what the market is telling us."
According to AN, that's the general attitude amongst Chevy and GMC dealers across the country, where the twin pickups are getting butchered in sales by competitors offering up to $9,000 off their sticker prices. Part of the problem for GM is that its trucks are arriving on the market near the end of the current F-150's lifecycle, a fact that Ford has taken advantage of.
