GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.

GM's Buckle to Drive teen safety feature comes to more models for 2021

In 2014, GM announced a feature called "Belt Assurance," which would prevent a vehicle from being shifted out of park until the driver and front passenger had buckled their seatbelts. Initially launched on certain fleet vehicles in 2014, the feature rolled out as a free option on the 2015 GMC Sierra, Chevrolet Colorado, Cruze and Silverado. At the time, GM said it would push Belt Assurance to more models if customers took to it. That appears to have happened; come 2019, GM repackaged Belt Assurance as Buckle to Drive, part of the automaker's Teen Driver System that bundled tech such as geofencing and speed limit warnings to help parents keep track of their children's driving habits. In that implementation, the system only works when Teen Driver Mode is activated, locking out the shifter and muting the radio for 20 seconds or until the seatbelts are buckled, whichever comes first. The system shows a visual warning in the gauge cluster, too.  For this model year, the Teen Driver System came standard on 10 Chevy models, but Buckle to Drive was only allotted to the Colorado, Malibu and Traverse. Later this year, the 2021 Camaro will join the Chevys outfitted with the Teen Driver System and will get Buckle to Drive in addition. GM Authority reports that for the 2021 model year, Buckle to Drive will also be picked up by the Cadillac CT4 and CT5. Previously, the Cadillac ATS, CTS, Escalade and XTS came with the Teen Driver System, but three out of those four vehicles are no more, and the 2021 Escalade makes no mention of the Teen Driver System nor Buckle to Drive among its safety features. Elsewhere around the GM empire, the Buick Envision and Encore GX include the Teen Driver System, as do six GMC vehicles, but it's not clear when any will be upgraded with Buckle to Drive. The tech could help save numerous teenagers' lives. On its page of teen crash facts, the Centers for Disease Control and Prevention writes that roughly 300,000 teens between the ages of 16 and 19 ended up in emergency rooms to treat crash injuries in 2017. Furthermore, "only 58.8% of high school students always wore seat belts when riding as passengers," and, "Among young drivers aged 15-20 who died in car crashes in 2017, almost half were unrestrained at the time of the crash (when restraint use was known)."

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.
