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.

Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.
Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released
He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
Tesla has finally released its Full Self-Driving v14 ‘Lite’ suite for older cars that equip the Hardware 3 or AI 3 chip, which have not been able to handle the newest versions of the company’s driver assistance software.
Tesla officially started releasing the v14 Lite suite to owners in the Early Access Program last night. The company’s Head of AI, Ashok Elluswamy, said that the rollout will continue over the next few weeks. The build distills the driving behavior from AI4’s v14 series into both the camera and compute configurations of an AI3 car.

It also includes a variety of new features that were available to AI4 cars running v14, including:
- Start Self-Driving from Park
- Arrival and Parking Options
- Speed Profiles
The release is highly anticipated because those owners with AI3 vehicles were early adopters into the FSD platform and were promised that their cars would be capable of achieving Full Self-Driving.
However, Tesla CEO Elon Musk admitted during the company’s recent Q1 Earnings Call that these vehicles would not be capable of achieving unsupervised Full Self-Driving, which is what Tesla had originally said.
Owners were not pleased with this answer, or the idea that their commitment to buying the suite outright for thousands of dollars would not yield the ability to drive without operating the car. Tesla gave some solutions for this, including a discount on a new car, or an upgrade to an AI4 or AI5 self-driving computer and new, upgraded cameras.
Tesla owners do not seem pleased with these options, as they require giving the company more money.
Nevertheless, it is important to note that Tesla came through for owners here by releasing v14 Lite before the end of Q2, something it had promised owners during the previous Earnings Call. Tesla has had trouble keeping up with timelines, but this is a big achievement for the team.
Tesla released what analysts believe the company will report in terms of deliveries and energy deployments for Q2, but the figures seem to confirm a long-standing theory on the company’s vehicle division.
For years, Tesla was just looked at as a car company. Now that it has established itself as a powerhouse in energy, AI, and tech as a whole, the company is now less hellbent on achieving quarterly growth, on a sequential basis, at least from a major standpoint.
Tesla topped out its annual deliveries in 2023 at 1.81 million, and in the two years since, the company has reported a decrease in deliveries for the entire 12-month term both times.
With Tesla delivering 358,023 cars in Q1, a 6.3 percent increase over Q1 2025, but falling short of Wall Street expectations at 365,000-370,000 units, the narrative around vehicle deliveries and their importance continued to change earlier this year. Some might say it is convenient, but others might say it is the typical evolution of a company that continues to change over time.
For Q2, Tesla’s delivery consensus estimates sit at 406,024 units, analysts believe. They were surveyed from Daiwa, DB, Wedbush, Cowen, Canaccord, Baird, Wolfe, BMP Paribas, Goldman Sachs, RBC, Evercore ISI, Barclays, Bank of America, Wells Fargo, Morgan Stanley, Truist, UBS, Jefferies, JPM, Needham & Co., HSBC, and William Blair.

Tesla is also expected to report deployments of 13.8 GWh this quarter.
The change to Tesla’s overall narrative now leans less on vehicle deliveries and more on its other projects. Most notably, Tesla’s Robotaxi project has taken the priority over most of its other business ventures, and investors and the public are more concerned about the deployment of vehicles into the fleet, the operation of a driverless ride-hailing service, Cybercab production and operation, and expansion into new cities.
Tesla analyst realizes one big thing about the stock: deliveries are losing importance
This big narrative switch happened when Tesla indicated it was looking at making transportation a service by launching a ride-hailing service that will operate using Tesla’s Full Self-Driving suite. Once unsupervised operation begins, Robotaxi could be a new way for people to get around, all without a driver in their car.
Instead, they will rely on the billions of miles Tesla has accumulated from its real-world fleet.
It is important to note that Tesla remains significant in the automotive sector, and deliveries must continue as they have for years. Tesla still has a strong automotive business and needs to execute further on all facets to keep its investors happy.
