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.

It won't be long now before Nissan Leaf finally overtakes Chevy Volt

The two best-selling plug-in vehicles ever are the Chevy Volt and the Nissan Leaf. When the two vehicles launched in late 2010, the plug-in hybrid Volt quickly outpaced the all-electric Leaf and, despite lots of ups and downs since then, continues to hold on to a cumulative sales lead. This will change in 2015. Cumulatively, from November 2010 through November 2014, the Volt sold 71,867 units while the Leaf trails with 69,220. That's a difference of just 2,647. Based on current trends (with the Leaf selling around 2,500-2,700 a month and the Volt at 1,500-1,700) we expect the Leaf to take over either in January or, more likely, February when the Leaf takes over as the most popular plug-in car in America. Perhaps even March, depending on how low the numbers are for January and February, which are always slow sales months in the US. Of course, once it takes the crown, the Leaf can't expect to easily hold on for long. A new Volt is coming in the second half of 2015, likely beating a new Leaf to market. The question is, then, how well the Chevy sells with all of its new bells and whistles. Do you think the Volt will be the comeback kid once the 2016 model becomes available?

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.
