Update: 3:46 PM EST 12/19: Quote from Aptera added to para. 6
Due to recent economic turbulence, the future of solar EVs is being called into question.
This morning, Sono Motors reservation holders were hit with a shocking notification; the company is on the verge of abandoning its solar electric vehicle project due to a lack of funds. A few weeks prior, solar EV brand Aptera announced that they would be making yet another prototype variation and pushing back its production start date. And while Lightyear Motors has begun producing its Lightyear 0 solar EVs, it is far from the scale many hoped for. So is this the end of solar EVs? It’s not immediately clear.
Starting with the announcement from Sono Motors this morning, the message was grim. Despite securing over 20,000 orders, they couldn’t secure the necessary investment to continue the development of their upcoming vehicle. However, this is not the end. At the very least, Sono will continue to produce solar panel technology as they already have been, but they also have another route. Sono is throwing a hail mary play and asking reservation holders to either increase their investment into the company, increase their downpayment, or even share the #savescion tag.
Looking to Aptera, many were optimistic earlier this year when the company showed off the Gamma prototype, a vehicle that at the time was supposedly production ready. Optimism was built further when Teslarati interviewed Aptera CEO Chris Anthony, where the CEO claimed that production would start in early 2023. Now it appears those plans may have changed.
Not only will Aptera be developing another prototype vehicle, the Aptera Delta, but production has become funding-dependent. And even with the funding, the company will be nine months away from beginning any delivery, according to a recent Aptera webinar.
Aptera Motors sent this comment in response to an inquiry from Teslarati:
Our development plan consists of four phases: Alpha, Beta, Gamma, and Delta. We have efficiently completed the first three phases and are currently in Delta, the final phase of Aptera’s path to production, which includes: the completion of our production-intent design, systems integration & Delta builds, crash testing and production validation, and lastly, the start of production. Once we meet our funding objectives, we will be able to provide a more accurate delivery timeline. In the meantime, we thank our reservation holders for their patience and continued support.
Finally, the glimmer of hope for solar EVs, Lightyear Motors has begun production of its solar EV in Finland. However, the company has been criticized for its small production volume and morose production timeline, only planning to produce 150 units. The company has defended the move as it plans for the vehicle to demonstrate technology ahead of a mass market option.
What is being seen in the solar electric vehicle space is colloquially called “production hell.” As countless EV startups have come to market over the past few years, there is a reason that essentially only Tesla, Lucid, and Rivian have actually made it to market; production is harrowing, and funding might be even more challenging.
Overall, the sad reality is that these EV startups are going through the gauntlet, and simply due to the challenge of introducing a new vehicle to the market, they are suffering for it. And while many consumers, engineers, and company CEOs have pointed out the benefits of solar EVs, that doesn’t necessarily mean they will make it to the market. Here’s to hoping that each of these manufacturers can work their way out of the woods and bring these remarkable technologies to the market.

Elon Musk’s X will start using a Tesla-like software update strategy
The initiative seems designed to accelerate updates to the social media platform, while maintaining maximum transparency.
Elon Musk’s social media platform X will adopt a Tesla-esque approach to software updates for its algorithm.
The initiative seems designed to accelerate updates to the social media platform, while maintaining maximum transparency.
X’s updates to its updates
As per Musk in a post on X, the social media company will be making a new algorithm to determine what organic and advertising posts are recommended to users. These updates would then be repeated every four weeks.
“We will make the new 𝕏 algorithm, including all code used to determine what organic and advertising posts are recommended to users, open source in 7 days. This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed,” Musk wrote in his post.
The initiative somewhat mirrors Tesla’s over-the-air update model, where vehicle software is regularly refined and pushed to users with detailed release notes. This should allow users to better understand the details of X’s every update and foster a healthy feedback loop for the social media platform.
xAI and X
X, formerly Twitter, has been acquired by Elon Musk’s artificial intelligence startup, xAI last year. Since then, xAI has seen a rapid rise in valuation. Following the company’s the company’s upsized $20 billion Series E funding round, estimates now suggest that xAI is worth tens about $230 to $235 billion. That’s several times larger than Tesla when Elon Musk received his controversial 2018 CEO Performance Award.
As per xAI, the Series E funding round attracted a diverse group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group, among others. Strategic partners NVIDIA and Cisco Investments also continued support for building the world’s largest GPU clusters.

Tesla FSD Supervised wins MotorTrend’s Best Driver Assistance Award
The decision marks a notable reversal for the publication from prior years, with judges citing major real-world improvements that pushed Tesla’s latest FSD software ahead of every competing ADAS system.
Tesla’s Full Self-Driving (Supervised) system has been named the best driver-assistance technology on the market, earning top honors at the 2026 MotorTrend Best Tech Awards.
The decision marks a notable reversal for the publication from prior years, with judges citing major real-world improvements that pushed Tesla’s latest FSD software ahead of every competing ADAS system. And it wasn’t even close.
MotorTrend reverses course
MotorTrend awarded Tesla FSD (Supervised) its 2026 Best Tech Driver Assistance title after extensive testing of the latest v14 software. The publication acknowledged that it had previously criticized earlier versions of FSD for erratic behavior and near-miss incidents, ultimately favoring rivals such as GM’s Super Cruise in earlier evaluations.
According to MotorTrend, the newest iteration of FSD resolved many of those shortcomings. Testers said v14 showed far smoother behavior in complex urban scenarios, including unprotected left turns, traffic circles, emergency vehicles, and dense city streets. While the system still requires constant driver supervision, judges concluded that no other advanced driver-assistance system currently matches its breadth of capability.
Unlike rival systems that rely on combinations of cameras, radar, lidar, and mapped highways, Tesla’s FSD operates using a camera-only approach and is capable of driving on city streets, rural roads, and freeways. MotorTrend stated that pure utility, the ability to handle nearly all road types, ultimately separated FSD from competitors like Ford BlueCruise, GM Super Cruise, and BMW’s Highway Assistant.
High cost and high capability
MotorTrend also addressed FSD’s pricing, which remains significantly higher than rival systems. Tesla currently charges $8,000 for a one-time purchase or $99 per month for a subscription, compared with far lower upfront and subscription costs from other automakers. The publication noted that the premium is justified given FSD’s unmatched scope and continuous software evolution.
Safety remained a central focus of the evaluation. While testers reported collision-free operation over thousands of miles, they noted ongoing concerns around FSD’s configurable driving modes, including options that allow aggressive driving and speeds beyond posted limits. MotorTrend emphasized that, like all Level 2 systems, FSD still depends on a fully attentive human driver at all times.
Despite those caveats, the publication concluded that Tesla’s rapid software progress fundamentally reshaped the competitive landscape. For drivers seeking the most capable hands-on driver-assistance system available today, MotorTrend concluded Tesla FSD (Supervised) now stands alone at the top.

Elon Musk’s Grokipedia surges to 5.6M articles, almost 79% of English Wikipedia
The explosive growth marks a major milestone for the AI-powered online encyclopedia, which was launched by Elon Musk’s xAI just months ago.
Elon Musk’s Grokipedia has grown to an impressive 5,615,201 articles as of today, closing in on 79% of the English Wikipedia’s current total of 7,119,376 articles.
The explosive growth marks a major milestone for the AI-powered online encyclopedia, which was launched by Elon Musk’s xAI just months ago. Needless to say, it would only be a matter of time before Grokipedia exceeds English Wikipedia in sheer volume.
Grokipedia’s rapid growth
xAI’s vision for Grokipedia emphasizes neutrality, while Grok’s reasoning capabilities allow for fast drafting and fact-checking. When Elon Musk announced the initiative in late September 2025, he noted that Grokipedia would be an improvement to Wikipedia because it would be designed to avoid bias.
At the time, Musk noted that Grokipedia “is a necessary step towards the xAI goal of understanding the Universe.”
Grokipedia was launched in late October, and while xAI was careful to list it only as Version 0.1 at the time, the online encyclopedia immediately earned praise. Wikipedia co-founder Larry Sanger highlighted the project’s innovative approach, noting how it leverages AI to fill knowledge gaps and enable rapid updates. Netizens also observed how Grokipedia tends to present articles in a more objective manner compared to Wikipedia, which is edited by humans.
Elon Musk’s ambitious plans
With 5,615,201 total articles, Grokipedia has now grown to almost 79% of English Wikipedia’s article base. This is incredibly quick, though Grokipedia remains text-only for now. xAI, for its part, has now updated the online encyclopedia’s iteration to v0.2.
Elon Musk has shared bold ideas for Grokipedia, including sending a record of the entire knowledge base to space as part of xAI’s mission to preserve and expand human understanding. At some point, Musk stated that Grokipedia will be renamed to Encyclopedia Galactica, and it will be sent to the cosmos.
“When Grokipedia is good enough (long way to go), we will change the name to Encyclopedia Galactica. It will be an open source distillation of all knowledge, including audio, images and video. Join xAI to help build the sci-fi version of the Library of Alexandria!” Musk wrote, adding in a later post that “Copies will be etched in stone and sent to the Moon, Mars and beyond. This time, it will not be lost.”
