GM to announce second U.S. battery plant, in Tennessee, with LG Chem, sources say

General Motors and South Korean joint-venture partner LG Chem will announce a second U.S. battery cell manufacturing plant on Friday, revealing plans for a $2.3 billion factory in Spring Hill, Tennessee, three people familiar with the matter said. The plant will use a different, more cost-effective battery chemistry than the one the companies will offer from the joint-venture plant they are building in Lordstown, Ohio, the sources said on Wednesday. The battery will be for the Cadillac Lyriq electric crossover vehicle that GM will begin building at its nearby Spring Hill assembly plant next year, the sources said. The timing of the Tennessee battery plant's opening is unclear, but there will be a period when the battery is supplied for the Lyriq by another LG facility until the Tennessee plant opens and it will not come from Lordstown, one of the sources said. GM would not confirm the details and declined further comment, and a spokesman for LG did not have an immediate comment. A Tennessee economic development spokeswoman also declined to comment. The No. 1 U.S. automaker previously said it was exploring the feasibility of another U.S. battery cell plant with LG's battery unit, LG Energy Solution, via its Ultium Cells LLC joint venture. Sources previously told Reuters that GM and LG Chem were in advanced talks with Tennessee officials, and that the plant there would be similar in scope to the $2.3 billion Lordstown plant. GM said in October it would invest $2 billion in Spring Hill to build EVs. The Detroit automaker said last year it was investing $27 billion in electric and autonomous vehicles over the next five years. Sources previously said GM would need more battery plants beyond the Tennessee one to meet aggressive EV targets. GM has set a target in January of halting sales of light-duty gasoline and diesel-powered vehicles by 2035. LG Energy said last month it planned to invest more than $4.5 billion in U.S. battery production over the next four years, including plans to build at least two new plants. LG had been embroiled in a high-profile dispute with rival South Korean firm SK Innovation in the United States after LG alleged SK stole trade secrets, but the companies settled that and other disputes with SK agreeing to pay $1.8 billion to LG.

Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.

Ghostbusters trailer stars Ecto1 and a quartet of actresses

"Um... you didn't disclose that the vehicle was going to be a hearse," says funnywoman Melissa McCarthy in the brand-spankin'-new trailer for the upcoming Ghostbusters reboot. Traditionalist fans may be similarly angered by the vehicle's basis, since the original Ecto1 was an ambulance, not a vehicle for the dead. Leslie Jones' response to McCarthy wasn't meant to answer those critics, but it does a good job of it anyway: "It's a Cadillac!" Naturally, there's a lot more to look at in the new trailer than just the Ecto1. There are, obviously, ghosts. Lots of 'em, in fact. There's also an opening piano sequence that's pretty darn great, but we ought to warn you that if you watch the video up above, you're going to be humming the theme from Ghostbusters for the rest of the day. We're sorry, but it simply cannot be avoided. You've been warned. Related Video:
