GM and LG Energy Solution will build their second battery plant in Tennessee

DETROIT — General Motors and South Korean joint-venture partner LG Energy Solution on Friday said they will build a second U.S. battery cell manufacturing plant, revealing plans for a $2.3 billion factory in Spring Hill, Tennessee. The planned 2.8 million-square-foot plant, scheduled to open in late 2023, will employ 1,300 people and will have production capacity of about 35 gigawatt-hours, similar to the companies' Ultium Cells joint-venture plant in Lordstown, Ohio, as they move to respond to the growing demand in the electric vehicle market. The plant's capacity would enable it to supply battery packs for more than 500,000 electric vehicles a year. "The addition of our second all-new Ultium battery cell plant in the U.S. with our joint venture partner LG Energy Solution is another major step in our transition to an all-electric future," GM Chief Executive Mary Barra said. The United Auto Workers on Friday called on GM to ensure the new plant is staffed with union-represented workers, which GM officials have said would be determined by the employees. LG Chem said in a regulatory filing that its LG Energy Solution unit will invest $933.5 million in the plant between this year and 2023. GM and LG Energy Solution will use a different, less-expensive battery chemistry in Tennessee than the one to be used in the Lordstown plant that opens next year, sources previously told Reuters. Sources have said the No. 1 U.S. automaker will need more battery plants beyond Tennessee to meet aggressive EV targets, including projected sales of more than 1 million EVs globally in 2025. GM's longer-range target includes halting sales of light-duty gasoline and diesel-powered vehicles by 2035. Most battery manufacturing is currently concentrated in China and Korea, while Tesla and Japanese partner Panasonic largely control most U.S. battery production. When it opens, the new GM-LG battery plant will supply batteries for the Cadillac Lyriq crossover EV that GM is slated to start building at its nearby Spring Hill assembly plant next year. LG is expected to supply the batteries from Korea until then. Supplier sources said a second Cadillac electric crossover, called Symboliq, is expected to join the Lyriq in production at Spring Hill in 2024, along with two new electric crossovers for Honda and its premium Acura brand. GM said in October it would invest $2 billion in Spring Hill to build EVs.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

Cadillac CT6 to be lighter than CTS, get PHEV model

Cadillac is suddenly one of the most talked about automakers in the US with Johan de Nysschen taking control. The brand claims that it eventually wants to become, once again, the standard of the world. One of the first vehicles to actually prove whether that's possible is its upcoming CT6 flagship sedan. We still don't know what the production version looks like undisguised, but other important details are falling into place. The latest big news sheds some light on the Caddy's powertrain and some estimates of its weight and size.
General Motors product chief Mark Reuss dropped the details at the automaker's Global Business Conference. According to The Detroit News, he revealed that the CT6 would use a twin-turbocharged, 3.0-liter six-cylinder engine with an eight-speed automatic transmission, and a plug-in hybrid would be an additional option. He reportedly claimed it would be the most "powerful six-cylinder gas engine in the segment" and said the hybrid could get around 70 miles per gallon.
Reuss also revealed that the CT6 would be about 53 pounds lighter than the current CTS, despite being about 8 inches longer, according to The Detroit News. If that's the case, the new flagship is about 203.5-inches long, which is 1.5-inches more than the XTS.
