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.

GM recalling 1.4 million older vehicles for oil leak fire risk

General Motors is recalling 1,411,332 older vehicles with its 3.8-liter V6 yet again due to a fire risk. Specifically, there are 1,283,340 of them in the US, and the affected models are the: 1997-2004 Pontiac Grand Prix 2000-2004 Chevrolet Impala 1998-1999 Chevrolet Lumina 1998-2004 Chevrolet Monte Carlo 1998-1999 Oldsmobile Intrigue 1997- 2004 Buick Regal The fault with these vehicles is that oil can drip onto the hot exhaust manifold during hard braking, which can potentially cause of fire. In the last six years, there have 19 reported minor injuries from this problem but no crashes or fatalities, according to the company. Spokesperson Alan Adler also told Autoblog: "GM has reports of 1,345 fires in vehicles that were repaired under two previous recalls for this issue." At this time, GM is still developing a remedy for the problem. According to Adler, the company advised owners to park these vehicles outside for the previous recalls. "The cars can be safely driven. In cases where a customer reported an engine fire while driving, smoke was reported, which would be an indication of a malfunction," he said. This is GM's fourth recall for this problem since 2008, according to The Detroit News. At one point it was believed that aging valve cover gaskets allowed the oil to leak out and drip onto the manifold. A campaign in 2009 covered nearly 1.5 million of these models through the 2003 model year for the same issue. At the time, dealers installed new spark plug wire retainers as a fix.

Seeing the Detroit Auto Show via drone

Seeing the Chevrolet display at the Detroit Auto Show is worth doing this year, and not just because of the new Corvette Z06, Volt and Bolt concept. In order to attract the new kids, The Bowtie has gone what the old kids used to call "buck wild" with their show stand at Cobo Hall. A Corvette Z06, Trax, and Colorado are parked along a central aisle, called Mainstreet, at the end of which is a 20-foot-tall, 73-foot long transparent screen lording over the new Volt. Elsewhere are five more 20-foot-tall screens broadcasting nine stories today's Chevrolet wants to tell about its vehicles, from performance to belief in the power of play to its 4G LTE-equipped OnStar telematics service. Then there are the social media and virtual reality safety installations, the community presentations and more. Chevrolet flew a drone through the stand to show off what it's doing, which is has replaced eye-level video as the next best thing to being there. You can check it out in the video above.
