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 Silverado WT gets its own murdered-out trim pack

Media days for the 2015 Chicago Auto Show ended last week, but that hasn't stopped Chevrolet from adding just one more thing. The Bowtie brand showed off three new trim packages for its trucks in the Windy City – the Colorado GearOn and the Silverado Midnight and Custom – but protests from consumers over the price of these equipment packs has led the company to release a new trim group for its most affordable fullsizer, the Silverado WT. The $1,595 Black Out pack will be available on both the regular- and double-cab Silverado WT and offers a few simple, stylistic upgrades. Five-spoke, 20-inch black wheels are the headlining item, although Chevy will also include "deep tinted glass" and black bowtie badges both fore and aft. Available only in black (the company even paraphrases old Mr. Ford in its press release), the new package adds just enough to class up the otherwise dreary looking Work Truck. Chevy has only released one image for the time being, available up top. Dealers, meanwhile, are currently taking orders. Check below for the brief press release. Chevrolet Silverado Work Trucks Get Blacked Out DETROIT – Chevrolet is adding a $1,595 Black Out package for regular- and double-cab 2015 Silverado 1500 WT models. It includes 20" black painted aluminum wheels, P275/55R20 all-season blackwall tires, deep tinted glass and black bowties. Prices start at $28,895. The package is available for order now, and customers can have any color they want, as long as it is black. Editors' Note: Manufacturer's Suggested Retail Price excludes tax, title, license, dealer fees and optional equipment. Includes dealer freight charges and option package discounts. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4.8 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature engaging performance, design that makes the heart beat, passive & active safety features and easy-to-use technology, all at a value.

GMC Canyon, Chevy Colorado diesels finally heading to dealers

Customers who have been waiting to receive their diesel-powered Chevrolet Colorados and GMC Canyons should be relived to hear that GM will finally start to ship them out of the Wentzville Assembly Plant. "The highly anticipated 2016 GMC Canyon diesel has begun shipping to dealers," a company spokesperson confirmed to The Detroit News. The trucks originally had a fall launch date, but a final review forced a delay in deliveries. The 2.8-liter four-cylinder diesel in the midsize trucks produces 181 horsepower and 369 pound-feet of torque, and the company touts the engine's low emissions. The Environmental Protection Agency and California Air Resources Board even put the mill through extra scrutiny with a real world test in the wake of VW's diesel scandal, and the Duramax passed with no problems. At that time, a Chevy spokesperson told Autoblog that the models' launch was on track. The Duramax engine adds $3,730 to the price of a comparable V6 model, but they're the most fuel-efficient pickups on the market. The EPA estimates the twins at 31 miles per gallon highway, 22 mpg city, and 25 mpg combined in two-wheel drive form and 29/20/23 with four-wheel drive. Buyers likely can't wait to finally experience these pickups after reading a heap of positive reviews. The Colorado diesel recently earned Motor Trend's Truck of the Year award. We also came away impressed with it during our First Drive and liked the Canyon during our Quick Spin. Related Video:
