GM laying off 500 workers to slow Chevy Sonic production

Due to slow sales of the Chevrolet Sonic and Buick Verano, General Motors is cutting a shift at the Orion Township plant that builds the pair. The move lays off about 500 workers, but most of them are expected to get offers to transfer to other factories, Automotive News reports. The move came just a day after GM announced adding 1,200 employees to the Detroit-Hamtramck plant. GM has been trying all year at the Orion Township factory to align production of the Sonic and Verano with their demand. The automaker first attempted idling the plant several times and eventually resorted to laying off about 100 workers. It also reduced the production rate there. With the huge rise in popularity of crossovers, demand for the plant's small cars is on the downturn. According to Automotive News, there's currently a 116-day supply of Sonics and 100 days of Veranos to sell. Delivers tell a similar tale because the Chevy is off 35.2 percent from January to September, and the Buick does little better with a 27.2 percent drop from the same period last year. While the situation at Orion Township might look rough now, big things are on the horizon. Soon, the new Chevy Bolt electric vehicle will be built there when it hits the market around 2017. Plus, the plant will also get a $245-million upgrade and 300 new jobs for another, unannounced vehicle.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.

Sunday Drive: Taking a gaze into the automotive crystal ball

Mankind has long been fascinated by the future. So it makes sense that this past week's top stories were all about cars, trucks, and SUVs that won't be hitting the market until the 2019 model year. And right at the top of the list is the Ram 1500. We've come to know Ram as the truck maker that styles its pickups with cues cribbed from big rigs, but that look has slowly evolved over time into something uniquely its own. The next Ram 1500 continues this trend, with a newly refined look that we can't wait to see in person. Up next is the 2019 Chevy Silverado. Pickup trucks have been, continue to be, and will remain the best-selling vehicles in America. And General Motors is a leader in the field, with two distinct offerings with which to entice buyers, one from the bread-and-butter Chevrolet brand and one wearing the slightly more upscale GMC badge. The Chevy looks to get LED lighting elements for 2019, which ought to keep the truck from looking dated when compared to the Ford F-150 and the previously mentioned Ram 1500. From there we move past pickup trucks and into SUVs and sedans. The 2019 Jeep Cherokee looks to get toned down a bit with its next refresh, and the '19 BMW 3 Series continues its slow evolutionary journey at the top of its aspirational sales pedestal. Finally, spy shots give way to official production reveals for the 2019 Audi A7 and Polestar 1. This pair of European luxury cars won't compete with one another – one is a rakish hatchback and the other a sports coupe – any further than for the eyeballs of our readers, but both proved popular enough to merit inclusion in our weekly roundup.
