General Motors is ditching its ‘Ultium’ name

General Motors has decided that it will ditch the “Ultium,” the name of its electric vehicle and battery technologies project, after several years of using it to denote things related to its development of EVs.

Before its Investor Event on Tuesday, GM said that it would drop the name in a statement, bringing an end to several years of developments that have fallen under the moniker:

“As GM continues to expand its EV business, the company is no longer branding its electric vehicle architecture, battery and cells, or EV components with the Ultium name, starting in North America.”

Make no mistake, the company is not ditching its development of EVs, batteries, or other technologies. All of those things will still be developed and remain under GM’s business, but the company saw it as time to lose the Ultium label for these projects.

Why? GM has already shifted its battery strategy to incorporate types and chemistries outside of the Ultium pouch cells. These are produced by LG with nickel, manganese, and cobalt.

It has already put $3 billion into a battery manufacturing deal for prismatic cells with Samsung SDI, and its VP of Battery, Kurt Kelty, told The Information earlier this week that it is hoping to simplify its battery strategy across multiple suppliers to optimize manufacturing and its vehicles:

“We’re moving from a single-source, single-form factor, single-chemistry to a multi-chemistry, multi-form factor, multi-supplier strategy. What we’re going to do going forward is really optimize for each vehicle.”

It’s also no secret that GM has struggled to truly get its EV segment moving to a point where it is comfortable. Chevrolet, a GM brand, was fourth in overall EV market share in the United States last year with 5.6 percent. Cadillac had 0.8 percent, GMC had 0.3 percent.

GM was the third-best-selling EV maker in the U.S. last year, holding 5.6 percent of the market. Tesla was first with 59.1 percent, and Ford was second with 6.5 percent, according to CleanTechnica data.

Although GM has its place on the podium, it, like Ford, has truly struggled to make a considerable dent in Tesla’s dominating market share. Ford decided to prioritize hybrids over EVs in an announcement earlier this year, shifting its focus as customers are more interested in the best of both ICE and EV engines.

Former Apple research scientist Yilun Chen has left the tech giant to join Tesla’s Optimus AI team. Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.

Apple veteran closes a major chapter

In a farewell note, Yilun Chen reflected on his tenure at Apple as a period defined by rapid growth and exposure to notable internal projects, some of which remain unreleased. His roles spanned engineering, research, early product incubation, and hands-on prototyping, allowing him to build expertise across both mature and emerging teams.

Chen credited mentors, colleagues, and cross-functional collaborators for shaping his trajectory, calling the experience unforgettable and emphasizing how each team taught him different lessons about scaling technology, guiding product vision, and navigating fast-moving research environments. “Each role has offered me invaluable unique lessons… My deepest gratitude goes to my colleagues, mentors and friends,” he wrote.

Tesla’s Optimus lab secured the hire

Chen said the move to Tesla was driven by the momentum surrounding Optimus, a humanoid robot powered by LLM-driven reasoning and Physical AI. After visiting Tesla’s Optimus lab, he admitted that he was “totally blown away by the scale and sophistication of the Optimus lab and deep dedication of people when I got to visit the office.”

His first week at Tesla, he noted, involved spontaneous deep-tech discussions, a flat team structure, rapid prototyping cycles, and what he called a “crazy ideas with super-fast iterations” culture. Chen emphasized that the team’s ambition, as well as its belief that humanoid robots are now within reach, creates an energy level that feels aimed at changing the world.

“You can feel the energy to change the world here,” he wrote in a post on social media.

Elon Musk gives nod to SpaceX’s massive, previously impossible feat

It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.

Elon Musk gave a nod to one of SpaceX’s most underrated feats today. Following the successful launch of the Transporter-15 mission, SpaceX seamlessly landed another Falcon 9 booster on a droneship in the middle of the ocean. 

It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight. 

Elon Musk celebrates a veteran Falcon 9 booster’s feat

SpaceX completed another major milestone for its Smallsat Rideshare program on Friday, successfully launching and deploying 140 spacecraft aboard a Falcon 9 from Vandenberg Space Force Base. The mission, known as Transporter-15, lifted off two days later than planned after a scrub attributed to a ground systems issue, according to SpaceFlight Now. SpaceX confirmed that all payloads designed to separate from the rocket were deployed as planned.

The Falcon 9 used for this flight was booster B1071, one of SpaceX’s most heavily flown rockets. With its 30th mission completed, it becomes the second booster in SpaceX’s fleet to reach that milestone. B1071’s manifest includes five National Reconnaissance Office missions, NASA’s SWOT satellite, and several previous rideshare deployments, among others. Elon Musk celebrated the milestone on X, writing “30 flights of the same rocket!” in his post. 

Skeptics once dismissed reusability as unfeasible

While rocket landings are routine for SpaceX today, that was not always the case. Industry veterans previously questioned whether reusable rockets could ever achieve meaningful cost savings or operational reliability, often citing the Space Shuttle’s partial reusability as evidence of failure.

In 2016, Orbital ATK’s Ben Goldberg argued during a panel that even if rockets could be reusable, they do not make a lot of sense. He took issue with Elon Musk’s claims at the time, Ars Technica reported, particularly when the SpaceX founder stated that fuel costs account for just a fraction of launch costs. 

Goldberg noted that at most, studies showed only a 30% cost reduction for low-Earth orbit missions by using a reusable rocket. “You’re not going to get 100-fold. These numbers aren’t going to change by an order of magnitude. They’re just not. That’s the state of where we are today,” he said. 

Former NASA official Dan Dumbacher, who oversaw the Space Launch System, expressed similar doubts in 2014, implying that if NASA couldn’t make full reusability viable, private firms like SpaceX faced steep odds.

Tesla AI and Autopilot VP hints that Robovan will have RV conversions

Tesla’s vice president of AI and Autopilot software, Ashok Elluswamy, hinted at the linitiative in a reply to Y Combinator CEO Garry Tan.

It appears that Tesla is indeed considering an RV in its future pipeline, though the vehicle that would be converted for the purpose would be quite interesting. This is, at least, as per recent comments by a Tesla executive on social media platform X.

Robovan as an RV

Tesla’s vice president of AI and Autopilot software, Ashok Elluswamy, hinted at the linitiative in a reply to Y Combinator CEO Garry Tan, who called for a startup to build RVs with Full Self-Driving capabilities. In his reply, Elluswamy simply stated “On it,” while including a photo of Tesla’s autonomous 20-seat people mover. 

Tesla unveiled the Robovan in October 2024 at the “We, Robot” event. The vehicle lacks a steering wheel and features a low floor for spacious interiors. The vehicle, while eclipsed by the Cybercab in news headlines, still captured the imagination of many, as hinted at by X users posting AI-generated images of Robovan RV conversions with beds, kitchens and panoramic windows on social media platforms. One such render by Tesla enthusiast Mark Anthony reached over 300,000 views on X.

Elon Musk on the Robovan

Elon Musk addressed the Robovan’s low profile in October 2024, stating the van uses automatic load-leveling suspension that raises or lowers based on road conditions. The system maintains the futuristic look while handling uneven pavement, Musk wrote on X. The CEO also stated that the Robovan is designed to be very airy inside, which would be great for an RV.

“The view from the inside is one of extreme openness, with visibility in all directions, although it may appear otherwise from the outside. The unusually low ground clearance is achieved by having an automatic load-leveling suspension that raises or lowers, based on smooth or bumpy road conditions,” Musk stated.

Elluswamy’s response on X suggests that Tesla is considering a Robovan RV conversion, though it would be interesting to see how the company will make the vehicle capable of reaching campsites. The Robovan has a very low ground clearance, after all, and campsites tend to be in unpaved areas.
