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.

A hybrid and electric Corvette, plus we drive the Ioniq 5 | Autoblog Podcast #728

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Zac Palmer. Zac drove the electric 2022 Hyundai Ioniq 5, and Greg drove the fire-breathing 2022 Maserati Levante Trofeo. The two dive deep into the relatively heavy news week by starting off with a discussion about the upcoming hybrid Corvette before chatting about what the electric Corvette might be like. They have a chat about the possibility of Porsche and Audi officially joining the Formula 1 field. Then, Greg and Zac get into some quick-hitting news to round out the segment by dissecting the updated Kia Soul (now without a turbo), the 30th Anniversary Edition Land Rover Defender and the new CEO at Aston Martin. Following the news and drive reviews, they rope in Senior Editor, Green John Beltz Snyder to give them a quick download of what went down at the first drive for the 2022 Ford F-150 Lightning. Finally, they reach into the mailbag and answer some questions from someone who is less than pleased about infotainment systems in some new cars. And lastly, the gang hears back from someone they helped out in a prior Spend My Money segment on the podcast. Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

First privately owned Corvette Stingray blitzes 1/4 mile in 12.23 at 114.88 mph

Chevrolet's latest road rocket, the Corvette Stingray, is a very quick car. If one needs further proof of that, we recommend they take a look at this video from Hennessey of what is claimed to be the first privately owned C7 Corvette to make a pass down the quarter mile. Not just any quarter mile, mind, this black C7 blitzed its way down the tuner's primary testing dragstrip. The Chevrolet ran the quarter in just 12.23 seconds at 114.88 miles per hour. That is a very quick time for a stock car.
Equipped with the Z51 package and a six-speed automatic transmission, not only does the C7 run a solid time, but it does so with little to no drama. That won't last though, as Hennessey will likely return it to its owner with far more power - we just hope they show a drag run of the completed product. Take a look below to watch the C7's 12.23-second run on video.
