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.

2022 Rivian R1T vs. 2022 Ford F-150 Lightning vs. GMC Hummer EV Pickup | How they compare on paper

The 2022 Rivian R1T has arrived, ushering in the era of the production electric pickup truck. The Rivian reviews are in, and spoiler alert: They're pretty good. Curious how the new battery-powered truck stacks up to its forthcoming competitors? Well, you've come to the right place. Rivian beat all of Detroit's big automakers to market in the half-ton segment, but probably not by the margin the startup would have liked. Ford's answer is the F-150 Lightning, which is due to enter production early next year, coming hot on the heels of GM's first entry into the space – the GMC Hummer EV pickup – which is scheduled to come off the line late this fall. While all three are pickups, they're aimed at distinctly different buyers, as a perusal of their specifications will reveal. Let's have a look, shall we?   Disclaimer: Before we dive in on this one, we'd like to note that while we've made our best effort to verify the specs provided, the Rivian is brand-new and the others are still in the prototype phase. Some of these figures may be inaccurate or may simply change before production. This is all hypothetical until you can actually cross-shop them anyway, right? Cool. End disclaimer. Let's start with the powertrains. They're all battery-electric trucks engineered on a modular rear-wheel-drive configuration engineered to accommodate (theoretically, anyway) up to four electric drive units. Rivian actually makes the most use of this with a quad-motor setup producing 835 horsepower and 908 pound-feet of torque with its high-output initial model. GMC's three-motor Hummer has the R1T beat with its estimated 1,000-horsepower output, while Ford's (also three-motor) comes in with a far more modest 563 horses. This is an excellent illustration of our above point that these are not all engineered for the same crowd. Ford's F-150, which comes in at a lower price point, is meant to be far more mainstream, as its power output suggests.  This theme continues when we look at the dimensions. Despite the image "Hummer" may conjure, GMC's entry actually needs the shallowest parking space. The Rivian is right behind it, with the work-truck-spec Ford extending more than a foot longer than either. What the Hummer lacks in length, it makes up for in girth. It's the widest by a good 5 inches. The Rivian is only slightly pudgier than the F-150, but it's much closer at that end of the scale.
