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.

2018 GMC Sierra 1500 Buying Guide | What you need to know about this pickup truck

The GMC Sierra is a work-capable truck that can be optioned like a luxury car. Variety and choice are the keywords for the Sierra, not to mention close rivals like the Ford F-150, Ram 1500, and Chevrolet's own Silverado 1500. A Sierra buyer has a seemingly infinite list of choices when it comes to specifying exactly what they need in their pickup. In terms of cab length alone, there are three choices – Regular, Double, and Crew – to go along with your pick of Short, Standard, or Long cargo bed. Engines range from a 4.3-liter V6, upward to a range-topping 6.2-liter V8 available in top trim levels like the SLT and Denali. The Sierra can be ordered with a choice of two- or four-wheel drive, and transmissions include both a 6- and 8-speed automatic, depending on your choice of powertrain and trim. Changes for the 2018 model year include the standard fitment of a rearview camera, along with a Tire Fill Alert system that lets the driver know when the correct pressure has been reached. A 7.0-inch touch-screen stereo system is also now standard equipment on base Sierras. Is the 2018 GMC Sierra Safe? The National Highway Traffic Safety Administration gives the 2018 GMC Sierra 1500 an overall crash-test rating of five stars. In front and side impact tests, the latest Sierra 1500 scored a five-star safety rating. A four-star rating was recorded in the Rollover resistance test – this rating applies to Sierra trucks fitted with either rear- or all-wheel drive. Because the Sierra is such a popular vehicle, it's worth noting that the NHTSA conducted crash tests on models fitted with both these drivetrains, and in two cab lengths. The Insurance Institute for Highway Safety, which provides ratings for new vehicles based on its own comprehensive crash tests, also tested two versions of the Sierra 1500. The extended cab model registered "good" ratings in all but one of the IIHS' crash tests. Driver side protection in the small overlap test was deemed "acceptable" – front passenger-side results were not rated. Headlight effectiveness was given an "acceptable" rating, dependent on trim level selected. Meanwhile, the ease of use of the Child Seat Anchors (LATCH) was deemed "acceptable" in the extended cab Sierra. Ratings dip slightly for the Sierra 1500 in standard cab format. Driver-side protection in the front small overlap test drops to "marginal," while the available LATCH system scored a "poor" for its ease of use.
