UAW rejects GM contract proposal but makes a counter offer

The United Auto Workers union said a new comprehensive offer made by General Motors Co late Monday to end a two-week-old strike was not acceptable and said it had made a new counterproposal. UAW vice president Terry Dittes said in a letter to members "there are many important issues that remain unresolved." The union is awaiting GM's next proposal. He said GM's offer came up short on many issues.  Dittes said GM made a "comprehensive proposal" at 9:40 p.m. Monday. "This proposal that the company provided to us on day 15 of the strike did not satisfy your contract demands or needs. There were many areas that came up short like health care, wages, temporary employees, skilled trades and job security to name a few." Dittes is the union's vice president for GM relations and the UAW's lead negotiator in these contract talks. "We have responded today with a counterproposal and are awaiting GM's next proposal to the union," he wrote. "Regardless of what is publicized in print or social media, etc., there are still many important issues that remain unresolved." The strike, in its third week, has cost GM more than $1 billion, according to J.P. Morgan analyst Ryan Brickman. He said the cost per day in potential profit is $82 million. However, another analysis, by East Lansing-based consultant Anderson Economic Group, put the losses at $25 million a day. And the effects of the strike are expanding. GM said Tuesday the strike has created a parts shortage that forced the automaker to halt production at its pickup and transmission plants in Silao, Mexico, temporarily laying off 6,000 workers. Silao is where GM builds its highly profitable four-door crew cab Chevy Silverado and GMC Sierra pickups. The strike has also forced GM to idle some Canadian workers, and many suppliers have been forced to halt operations. About 48,000 UAW members went on strike on Sept. 16 seeking higher pay, greater job security, a bigger share of the leading U.S. automaker’s profit and protection of their healthcare. 

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.
