Kazuo Tadanobu, the CEO of Panasonic’s energy division, recently shared some insights about the company’s upcoming 4680 batteries, which would be sold to longtime partner Tesla. Tadanobu mentioned a number of key observations about the upcoming batteries, particularly on how the 4680 cells could effectively initiate change in the transportation sector.
Panasonic has been working on its 4680 battery for about a year and a half now, and it has not been easy. According to the executive, the development of the new batteries has “taken an immense amount of stamina.” This was because creating 4680 batteries is not as simple as enlarging existing cells. Tadanobu noted that changing the entire shape of the cell took “considerable nerve,” and that Panasonic “didn’t know how they would be received” by Tesla.
Fortunately for Panasonic, Tesla has reportedly acknowledged the Japanese company’s work on its 4680 batteries. Tesla has reportedly deemed Panasonic’s 4680 cells viable, as they meet the level of performance that the American electric vehicle maker is seeking. This is a good sign for Panasonic’s 4680 program, considering that Tesla itself is also ramping the production of its in-house 4680 cells.
Tesla’s home-grown 4680 cells will likely see their initial deployment in the Made-in-Texas Model Y, which will be produced at Gigafactory Texas. So far, Tesla’s 4680 production is limited to the company’s pilot line in Kato Road, close to the Fremont Factory. That’s a facility that has the potential to ramp to 10 GWh per year, but it’s still being improved today, with the company announcing last month that it had produced its 1 millionth 4680 battery cell in January. Tesla would likely need as many 4680 batteries as it could get, considering the launch of upcoming vehicles such as the Cybertruck, Semi, and new Roadster.
Panasonic, for its part, has been sharing its battery partnership with Tesla with rivals such as LG Energy Solution and Contemporary Amperex Technology Co. (CATL), both of which are extremely aggressive. Yet despite the rising competition, such as LG Energy Solution previously stating back in 2020 that it intends to be Tesla’s primary battery supplier in the future, Panasonic believes that the quality and safety of its batteries would speak for themselves.
According to Tadanobu, Panasonic’s advantage in the market lies in its capability to “use craftsmanship to maintain safety even while raising the performance of a battery.” And after leading the development of the next-generation cells, the executive noted that Panasonic would work very hard to retain its spot. “We don’t want to lose,” the Panasonic executive said.
Overall, the executive explained that Panasonic’s hard work in developing 4680 batteries for clients like Tesla is due to the company’s belief that the cells themselves have the potential to change the world of transport. If 4680 battery cells become successful, they would have a considerable impact in lowering the cost of electric vehicles. And if this happens, electric vehicle adoption would likely increase. “We see them as a new path forward,” Tadanobu said.

Tesla Full Self-Driving v14 ‘Lite’ Release Notes: new capabilities and features
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 Full Self-Driving v14 ‘Lite’ for older cars finally gets released
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 Q2 delivery consensus confirms this long-standing theory
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.
