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.

Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.

Porsche and Buick earn top honors in J.D. Power Sales Satisfaction Index Study

Customer satisfaction with car buying has been at a low point over the past few years, as price increases, inventory shortages, and COVID restrictions have complicated every part of the process. There are signs of improvement, however, as J.D. Power’s 2023 U.S. Sales Satisfaction Index Study showed that customer satisfaction has improved slightly from a year ago. J.D. Power rates satisfaction on a 1,000-point scale, finding that it improved seven points to 793 from last year. Improving inventory levels and a slow leveling off of prices have contributed to that improvement, and fewer people are paying above MSRP for new cars. Some auto brands performed better than others with sales satisfaction. Porsche ranked highest among premium brands, followed by Alfa Romeo. Buick took the top spot among mass-market brands, with GMC, Chevrolet, and Mitsubishi behind. J.D. Power also handed out segment-level awards: Premium Cars: Porsche Premium SUV: Porsche Mass-Market Car: Chevrolet Mass-Market SUV/Minivan: GMC Mass-Market Truck: GMC Despite the increase in sales satisfaction, thereÂ’s still room for improvement to reach pre-pandemic levels. J.D. Power noted gaps in salesperson knowledge as an area of improvement. Buyers rated salespeople much better during a gas vehicle purchase than with EVs, citing their expertise as a challenge. Pricing remains a challenge despite an improvement since 2022, and satisfaction is still below pre-pandemic levels. Mass-market buyers reported a slight bump in satisfaction, while premium buyers felt that pricing was less fair than a year before. ItÂ’s an interesting contrast, showing that dealer pricing tactics can significantly impact satisfaction with the sales process. Fewer people may be paying more than MSRP, but several premium models still list with significant markups. Even more interesting is PorscheÂ’s top spot on the satisfaction list, as its cars often sell with huge upcharges, and itÂ’s exceedingly tricky even to get a build allocation for some models.
