Torque time | 2017 GMC Sierra HD First Drive

It's not the truck that counts, it's how you use it. It's the heavy stuff you fit in its bed or the extremely heavy stuff that gets hooked up to the tow hitch. The ATV, the Jet Skis, the trailer with more square footage than a Greenwich Village apartment. Perhaps you need to get Seabiscuit or, uh, Mr. Ed to wherever they need to gallop next. In our case, there's a pair of very serious-looking snowmobiles perched atop the bed of a GMC Sierra. They spread out as wide as the extended tow mirrors, and their back halves are dangling precariously beyond the truck. Sterling Archer would be giddy; I'm a little nervous. But only because canyon roads and wide vehicles with a high center of gravity go together like peas and custard. The added weight is no sweat at all. That's because this is the 2017 GMC Sierra HD Denali, a truck with the sort of enhanced power, torque, suspension, and stopping capability expected of a heavy-duty pickup. And for this year, the power and torque get a serious bump courtesy of a new 6.6-liter Duramax turbodiesel engine reengineered from almost the ground up with 90 percent new parts. It's quieter and more efficient and it emits less, while most importantly producing 445 horsepower and 910 pound-feet of torque. That's up from 397 and 765, respectively. Chevy fans will note that the same engine is also available in the updated 2017 Silverado HD. Now, for those keeping score at home, that horsepower is best-in-class but the torque number still falls short of the new Ford Super Duty and its Power Stroke diesel V8's 925 lb-ft. Aw shucks. For the record, GM's engineers didn't seem too concerned that they weren't able to eke out an extra 16 torques just to say they're No. 1. "We wanted to first meet emissions and then deliver the maximum horsepower and torque we could, and deliver it over the widest usability range possible," said chief engineer Eric Stanczak. And let's be honest here, 910 pound-feet is herculean, and once again, a jump of 145 lb-ft. Or one Subaru Impreza's worth. Or 110 more than the best Ram can do on a 2500, and its Cummins turbodiesel's 800 pound-feet was eye-popping not too long ago. (The Ram 3500 maxes out at 900 lb-ft with the right transmission.) Ah, but here's the rub. That Cummins-equipped Ram 2500 can still tow more weight according to SAE-compliant measurements – 17,510 pounds for a Ram crew cab with a short bed versus 13,000 in the similar Sierra 2500. The Ford F-250 can manage 15,000.

GM hard at work on Chevy Silverado and GMC Sierra PHEV pickups

Autoweek heard from sources at General Motors and Ford about how each automaker is addressing the dip in EV enthusiasm and sales. At General Motors, AW reports, "plug-in hybrid versions of the Chevrolet Silverado and GMC Sierra are headed to market, in a hurry." The sources gave no timeline for when the trucks might appear. GM CEO Mary Barra told analysts during GM's Q4 2023 earnings call, "Let me be clear, GM remains committed to eliminating tailpipe emissions from our light-duty vehicles by 2035, but in the interim, deploying plug-in technology in strategic segments will deliver some of the environmental benefits of EVs as the nation continues to build its charging infrastructure."  It's too soon to predict how the Chevy Silverado EV and GMC Sierra EV will fare on the market, the Silverado EV Work Truck still the only one available to customers. It might be better for GM if they're not too popular at first, the automaker's cautious EV production ramp-up and recent software setbacks responsible for some still-healthy reservation rolls. Barra said the company plans to build between 200,000 and 300,000 EVs, this year, which would clear that backlog. Heading into the end of February, with the Chevy Bolt out of the picture and additional EV pickup production pushed to 2025, our Spidey senses feel those are optimistic numbers. The Chevy Bolt was the third-best-selling EV in the U.S. last year, at 62,044 units. GM didn't have another vehicle in the top ten. Furthermore, the combined sales of every EV in the top ten after the Bolt — seven models from six manufacturers — is only just over 200,000 units. The Blazer EV and Equinox EV could make it happen, but there's no way Chevy wants to rush those, the Blazer EV still in software purgatory.   The report speaks of collateral damage, GM said to have canceled an electric pickup sized below the Ford Maverick and Hyundai Santa Cruz. Automotive News said it saw the truck in January 2023, describing it as a futuristic two-door with a low roof and a 4.5-foot cargo bed. A new full-size van program supposedly got the axe as well, eliminating the plan to put a new Chevy Express and GMC Savana on a Brightdrop EV chassis. Over at Ford, AW says its sources mentioned another canceled midsizer; Ford's apparently stopped working on an EV pickup sized a bit below the Nissan Frontier.

GM might outsource vans to AM General

General Motors will possibly boost production of the Chevrolet Colorado and GMC Canyon at the Wentzville Assembly Plant in Missouri by contracting out some commercial van manufacturing to AM General. Demand for the two midsize trucks continues to boom, and GM would like to take advantage of the strong market for them. The possible deal came to light in a letter to workers at the factory, according to Automotive News. "This potential partnership would free up production capacity and allow the organization to capitalize on our ability to build midsize trucks to further satisfy customer demand," a portion of the document allegedly said. AM General would reportedly only take over assembly of the cutaway versions of the Chevy Express and GMC Savana. Customers and critics have quickly embraced the latest Colorado and Canyon since their introduction. The Chevy just won back-to-back Motor Trend Truck of the Year awards. GM also had to add a third shift and extra workers in 2014 just to keep up with demand. The Wentzville plant even increased employment on the weekends earlier in 2015 to assemble an extra 2,000 of the trucks each month. While the two pickups boom, deliveries for the Chevy Express and GMC Savana are down 26.9 percent and 26.6 percent respectively through the first 10 months of the year. GM doesn't break out numbers for the cutaway versions, but they make up about a third of production, according to Automotive News. AM General built the Humvee for the US military and does some contract work with automakers. For example, the company's Indiana factory now produces the Mercedes-Benz R-Class for export to China. Here's hoping this potential deal will help both GM and AM General keep their factories humming. Related Video:
