Chevy gets cracking on Cruze EV fleet testing

The Chevrolet Volt hasn't yet gone on sale, but General Motors is looking at ways of expanding its electric vehicle lineup. Chevy, along with partner LG, is employing a group of all-electric cars in the form of the Cruze. The sedans are part of a demonstration fleet which is located in Seoul, South Korea and is being used to provide data in an electric vehicle research project. The goal is to gather information on driving patterns and charging behavior in addition to consumer acceptance.
The Cruze EVs, along with some Daewoo Lacetti Premieres EVs, are the first fleet of full-size electric vehicles and should provide invaluable information for The General. Staying full-size means not sacrificing cargo space, so the battery pack is mounted to the underbody, leaving the trunk area open for plenty recyclable, canvas grocery bags.

GM pickup truck plant in Flint to add 1,000 assembly workers

FLINT, Mich. — General Motors said Tuesday it will add 1,000 workers to build new heavy-duty pickup trucks at its plant in Flint, Michigan, and will give priority to GM workers who were laid off elsewhere. The announcement comes the day after GM said it was starting to hand pink slips to about 4,000 salaried workers in the latest round of a restructuring announced in late November that will ultimately shrink its white-collar workforce in North America by 15 percent out of 54,000. GM has come under fire from U.S. President Donald Trump and Midwestern lawmakers for its plans to stop production at five North American factories and cut up to 15,000 jobs in all. The automaker has said it is trying to find new jobs for 1,500 U.S. hourly workers at the affected plants. Flint's truck plant could be a haven for many of these employees. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM on Tuesday will celebrate the launch of a new generation of heavy-duty GMC and Chevrolet pickups at the assembly plant in Flint, Michigan, that is now building all such trucks for the company. Elsewhere in the company on Monday, two people briefed on the cuts in the white-collar salaried workforce said GM is cutting hundreds of jobs at its information technology centers in Texas, Georgia, Arizona and Michigan and more than 1,000 jobs at its Warren, Michigan Tech Center. GM is filing new required mass layoff notices with state agencies and disclosed the cuts to lawmakers. The largest U.S. automaker announced in November it would cut a total of about 15,000 jobs and end production at five North American plants. The cuts include eliminating about 8,000 salaried workers, or about 15 percent. GM cut about 1,500 contract workers in December and said 2,300 salaried workers accepted buyouts, officials said. "These actions are necessary to secure the future of the company, including preserving thousands of jobs in the U.S. and globally. We are taking action now while the overall economy and job market are strong, increasing the ability of impacted employees to continue to advance in their careers, should they choose to do so," GM spokesman Pat Morrissey said, adding the bulk of the cuts should be completed in the next two weeks. Morrissey said GM would provide salaried workers with severance packages and job placement services.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
