GM recalling 8.4M cars, 8.2M related to ignition problems

General Motors today announced a truly massive recall covering some 8.4 million vehicles in North America. Most significantly, 8.2 million examples of the affected vehicles are being called back due to "unintended ignition key rotation," though GM spokesperson Alan Adler tells Autoblog that this issue is not like the infamous Chevy Cobalt ignition switch fiasco.
For the sake of perspective, translated to US population, this total recall figure would equal a car for each resident of New Hampshire, Rhode Island, Montana, Delaware, South Dakota, Alaska, North Dakota, the District of Columbia, Vermont and Wyoming. Combined. Here's how it all breaks down:
7,610,862 vehicles in North America being recalled for unintended ignition key rotation. 6,805,679 are in the United States.

More than 100 pink Cadillacs assemble for Aretha Franklin’s funeral today

Aretha Franklin's funeral service is under way today in Detroit, and plans call for a service of at least five hours featuring performances by stars including Stevie Wonder, Ariana Grande and Chaka Khan, speakers including former President Bill Clinton and the Rev. Al Sharpton, and at least 130 pink Cadillacs lining the road in front of the church. The gesture is a nod to Franklin's Grammy award-winning 1985 hit "Freeway of Love" and its lyrics about driving in a pink Cadillac. Crisette Ellis, the wife of Bishop Charles Ellis III of Detroit's Greater Grace Temple, said they were inspired by how police line up their cars during funerals for fallen officers. "My husband said, 'Wouldn't it be awesome if we could have a sea of pink Cadillacs parked on Seven Mile Road to greet Ms. Aretha Franklin as she arrives?'" she told NPR.

"They're coming from everywhere," she said. "They are coming from as far as Texas; Omaha, Nebraska; Florida; North Carolina; Maryland." The funeral, which officially kicked off at 10 a.m. EST at Greater Grace, caps a weeklong celebration of Franklin's life and songs, including a two-day visitation at the Charles H. Wright Museum of African American History and concerts. Performers also include Faith Hill, Jennifer Hudson and the Clark Sisters, while Tyler Perry and the Rev. Jesse Jackson are also scheduled to speak. HLN and the Word Network, plus several local Detroit television affiliates, plan to broadcast the funeral, and outlets including The Associated Press and USA Today plan to livestream it. Having sung at the inaugurations of three presidents — Jimmy Carter, Bill Clinton and Barack Obama — Franklin was an American institution. She was awarded the Presidential Medal of Freedom by then President George W. Bush in 2005. Clinton entered the church with his wife, Hillary, to loud applause and stood quietly by Franklin's open casket before the service started. Franklin's body was dressed in a golden sequined outfit. The funeral was closed to the public, but crowds of fans gathered outside, many dressed in their church best.

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.
