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 files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

2019 GMC Sierra 1500 prototype shows off differences from Silverado

Now that the new Silverado has made its debut, we're awaiting the reveal of its mildly restyled twin, the GMC Sierra 1500. While it likely won't be that different as far as capability and major equipment are concerned, we are looking forward to seeing what design changes it will have. Based on these recent spy shots, the changes will be mild, but still enough to make it visually distinctive. One of the more obvious differences will be in the front fascia treatment. Unlike the Silverado's grille that's level with the top of the headlights, the GMC's will rise above the lights, which will also yield a slight drop on each side of the hood to meet the lights. The grille is quite tall, extending far below the headlights, too. We can make out, behind some mesh, two dips on the outer edges of the grille that give the Sierra a more menacing frown. Large foglights are also found right near where the scoops for the wheel air curtains, and the headlights are unified on the edges, rather than split on the Silverado. Along the sides, the sheet metal looks relatively unchanged. At some angles, we can make out the distinctive shoulder line from the Silverado that runs up to about the rear mirrors where it stops to make room for another crease that rises up from somewhere in the middle of the front doors to lead to the front. The wheel arches are decidedly different from the Silverado's though. While the Silverado has fairly rounded arches, the Sierra's have a rear-slanted bevel to the fronts of the arches and a rounded 90-degree corner at the rears. There isn't much we can tell about the rear except for the taillights. They're quite large, and unlike the Silverado's, there aren't any areas where the sheet metal intrudes. It also appears that the tops of the taillights extend farther forward into the bed sides than the Chevy's. Because the Sierra has almost always been a mechanical twin of the Silverado, we expect it to offer the same 5.3-liter and 6.2-liter V8s, as well as the new 3.0-liter diesel inline-6. Also, being a GMC, it will likely have a flashy, chrome-laden Denali trim level. We also will see the fully revealed model soon, as Automotive News reports the debut will be on March 1.
