GM cutting production at two plants

General Motors is continuing to adjust to excess supply of some of its brands' models. To get production more in line with the vehicles' actual demand, the automotive giant is idling two of its factories in North America in the coming months. The Orion Assembly plant is going to be down from March 9-13, according to an anonymous plant worker and another insider speaking to Automotive News. The factory builds the Chevrolet Sonic and Buick Verano, but there are plenty of both models sitting on dealer lots, including 216 days worth of Sonics, according to AN. The factory already had two idle periods announced to reduce the excess. In addition, downtime is scheduled at GM's "Flex" line at the Oshawa, Ontario, Canada, plant from April 13-17. This affects supply of the Chevrolet Camaro, Impala, Buick Regal and Cadillac XTS. Among them, the automotive giant has the largest supply of Regals ready for dealers with 213 days worth of them, according to AN. The future for the whole Oshawa factory is cloudy in general, though. There are rumors that it could close entirely in the future because the Camaro is leaving and the Regal and XTS might not last much longer than 2017. The Canadian government and the labor union there intend to put up a fight, though.

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.

National Corvette Museum to recreate sinkhole experience for patrons [UPDATE]

UPDATE: The Thunderdome at the National Corvette Museum is not a ride; instead it's an experience that mixes digital graphics and thundering sound. For a brief period, it looked like the National Corvette Museum was going to preserve that sinkhole that ate eight important 'Vettes last year. After all, tourism boomed there afterwards. However, keeping the crater would have been more expensive than just doing the repairs. The museum isn't ready to let people completely forget, though, and now intends to make a major attraction out of a recreated version of the calamity. The museum's plan turns the sinkhole disaster into an amusement park ride called the Thunderdome, according to GM Authority. In a smaller recreation of the Skydome, 15 people at a time would get to watch an imitation of the sinkhole devouring the eight Corvettes. To make the experience even more immersive, visitors would get to view this all from an artificial, underground cave. If you missed seeing the actual pit, this would certainly be a bizarre way to experience it. According to GM Authority, the exhibit would also include an explanation of how sinkholes occur. The Corvette museum reportedly wants the attraction open by this fall.
