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.

Recharge Wrap-up: Chevy Volt class action suit proposed, Tesla stock could outperform in 2015

A class action suit has been proposed against General Motors for a steering problem in the Chevrolet Volt. The plaintiffs claim that a defect can cause the steering to freeze intermittently, and that General Motors either knows or should have known about the problem. The case, filed in New Jersey, also claims that defective parts are replaced with the same or similar parts, which are also defective. The plaintiffs say that claims for the 100-plus-member class exceed $5 million. Read more at Law360 or at BigClassAction. Tesla Motors stock (TSLA) has risen after weeks of losses. It gained 5.4 percent during the week ending December 19, when it closed at $219.29 per share. Since then, it rose slightly more, closing at $222.26 on December 24. Morgan Stanley lowered its target price on Tesla stock from $320 to $290, predicting lower sales on the upcoming Model III than expected before, but still called Tesla a good long-term investment. Analysts at CNBC predicted Tesla to be the best performing stock of 2015. Read more at ETF Daily News. Oslo- and New York-based architecture firm Snohetta has designed a zero-emissions house that also charges an electric car. The ZEB Pilot House, built in Larvik, Norway, uses a solar panel on the roof to power the house, which also provides enough excess energy to charge an EV. To make the most of energy most efficiently, the house uses smart technology to use as much energy as it can once it's harvested. This means one can turn on appliances like the washing machine remotely while the sun is at the optimum angle in the sky - perhaps during mid-day when the residents are at work. The house also uses organic materials and is designed to save as much energy as possible. Read more at Wired.

GMC Canyon, Chevy Colorado diesels finally heading to dealers

Customers who have been waiting to receive their diesel-powered Chevrolet Colorados and GMC Canyons should be relived to hear that GM will finally start to ship them out of the Wentzville Assembly Plant. "The highly anticipated 2016 GMC Canyon diesel has begun shipping to dealers," a company spokesperson confirmed to The Detroit News. The trucks originally had a fall launch date, but a final review forced a delay in deliveries. The 2.8-liter four-cylinder diesel in the midsize trucks produces 181 horsepower and 369 pound-feet of torque, and the company touts the engine's low emissions. The Environmental Protection Agency and California Air Resources Board even put the mill through extra scrutiny with a real world test in the wake of VW's diesel scandal, and the Duramax passed with no problems. At that time, a Chevy spokesperson told Autoblog that the models' launch was on track. The Duramax engine adds $3,730 to the price of a comparable V6 model, but they're the most fuel-efficient pickups on the market. The EPA estimates the twins at 31 miles per gallon highway, 22 mpg city, and 25 mpg combined in two-wheel drive form and 29/20/23 with four-wheel drive. Buyers likely can't wait to finally experience these pickups after reading a heap of positive reviews. The Colorado diesel recently earned Motor Trend's Truck of the Year award. We also came away impressed with it during our First Drive and liked the Canyon during our Quick Spin. Related Video:
