A series of articles on Sina Finance, a leading Chinese finance news organization, recently reported that Tesla’s FSD would soon start rolling out in China. Although there have also been reports of delays, Tesla appears to have finally addressed those regulatory issues as it has now officially started rolling out FSD in China.
FSD is being enabled with software update 2024.45.32.12 to owners who have purchased FSD outright. However, it isn’t clear whether this is exactly the same FSD as North Americans know it.
Urban Road Autopilot Assistance
This software update introduces “Urban Road Autopilot Assistance” (let’s call it URAA for short), an FSD-based driver-assistance system for Chinese Tesla owners. On controlled-access highways and urban roads, URAA guides vehicles according to navigation routes, assisting with entering and exiting highways, navigating intersections, and recognizing traffic lights to perform actions like going straight, turning left or right, or making U-turns.
Same FSD as North America?
While URAA shares many similarities with Tesla’s Full Self-Driving based on the information Tesla released, it’s not clear whether its functionality is exactly the same. It could just be FSD under a different name, or it could be slightly different.
Based on initial videos (shown below), FSD looks very capable and similar to what we’re used to. In the video, you can see the vehicle using its turn signals to go around vehicles, stopping at red lights, and making turns. It also slows down appropriately when there are pedestrians nearby. If there are differences between North American “FSD” and URAA, Tesla doesn’t make it clear what they are.
It appears that FSD in China is trained on its own set of data, as China did not want Tesla to use data from other countries to train their system, so there could be some limitations or differences between what’s available in North America and China. However, it’s also possible that it’s just a name change and Tesla was not allowed to use the term “Full Self-Driving" in China.
The full suite of FSD visualizations are also available in China with this update. They appear to be the same ones available in North America and we haven’t been able to detect any differences so far. However, it’s great to see additional owners being able to experience them for the first time.
Navigation Update
In September 2024, Tesla added the FSD option in Chinese vehicles, but it was just greyed out and required a navigation update. With this FSD update going out, Tesla is also requiring users to update the navigation maps to version CN-2025.8 before FSD can be enabled.
Most Teslas Now Have Access to FSD
This is Tesla’s first release of FSD outside of North America, which millions of customers have been waiting to see. Just recently, Tesla released FSD in Mexico, and before that, it expanded it to Puerto Rico, making it now available in four countries. Since North America and China are Tesla’s two largest markets, Tesla’s FSD is now available to the majority of Tesla owners, the first time this has happened.
While Tesla initially faced difficulty in getting regulatory approval in China due to data transmission laws, it appears Tesla is making progress with regulatory laws outside of the United States. Europe and Oceania are the next two phases for FSD, with Europe likely coming first due to it being a left-hand drive market.
While it’s not surprising to see FSD released in China, we expected more of a hold-up due to Chinese laws, so this is an encouraging sign of Tesla being able to work around country-specific laws.
In Tesla’s 2024 roadmap, Tesla said that it’d release FSD in China and Europe in Q1 2025, which it has partially achieved. The next step appears to be Europe, where many users are anxiously awaiting.

Tesla’s Megapack is rapidly becoming a key component in energy storage and grid modernization efforts worldwide. Though often associated with powering AI infrastructure or industrial operations, Megapack’s true strength lies in its ability to stabilize electrical grids during blackouts and brownouts.
In a recent behind-the-scenes reveal, Tesla showcased the impressive scale of Megapack production at its Mega Lathrop facility, along with real-world examples of how these systems are already transforming energy resilience across the globe.
Mega-Scale Megapack
Tesla is operating the largest utility-scale battery manufacturing facility in North America at Mega Lathrop, which has the capacity to produce 10,000 Megapacks annually. Thanks to a highly automated assembly process that uses over 30 welding robots to assemble the core Megapack structure. This is the largest manufacturing fixture Tesla uses— likely to only be matched by future developments at Mega Shanghai.
Tesla uses a highly automated powder coating process, utilizing over 90 robotic paint atomizers to apply more than 140 pounds of powder coat to each Megapack. This process delivers Tesla’s signature white reflective finish, engineered for long-term durability and corrosion resistance that lasts up to 20 years, even in harsh coastal or high-heat environments.
All of Megapack’s power electronics are designed and built in-house. Each Megapack uses 24 battery modules, electrical busing, and thermal management systems to ensure grid reliability and help to maximize energy density. The architecture pairs each inverter with a battery module to maximize energy availability and overall uptime. Plus, before each Megapack ships its way across the world, Tesla performs rigorous on-site quality control to ensure that the installation process is as seamless as possible.
Watch Tesla’s video of the manufacturing process below:
Megapack’s Real-World Impact: Hawaii
The core purpose of Megapack is to make power grids more stable and resilient while also reducing reliance on dirty peak power plants like coal. They achieve this by balancing energy supply and demand in real-time, smoothing out fluctuations from variable renewable sources like solar and wind, which helps to prevent grid shortages.
Hawaii actually provides the most real and down-to-earth example of Megapack’s impact. In mid-2024, the Kapolei Energy Storage facility in Hawaii came online. Hawaii utilized 258 Megapacks with a combined capacity of 565 MWh, successfully replacing the state’s last coal-fired power plant. This single facility can power approximately 20% of Oahu’s peak electricity needs by itself for approximately 4 hours.
The project is more than just removing coal plants, though. It serves as an example of Megapack’s grid integration and grid forming technology. The Kapolei Energy Storage facility can manage grid fluctuations caused by weather changes impacting renewable energy, improving stability and preventing blackouts. Thanks to their rapid inverter response times of under a millisecond, Megapacks participate in complex grid balancing activities, including fast frequency and voltage support, which helps to maintain grid balance throughout the day. Beyond that, Kapolei also allows Hawaii to black-start the grid in case of a major power outage that takes out a large section of the grid.
This functionality would be especially useful in Spain, where black-starting the grid took over eight hours recently and is still disrupting the day-to-day life of people there.

In this article, we’ll cover Tesla’s updates on Optimus, batteries, and Tesla Energy.
Optimus
Tesla has been working away on their humanoid robot and continues to make progress in software and hardware.
First, Tesla is preparing the Fremont factory for the Optimus pilot production line, which is scheduled for completion later this year. Once it is, wider deployments of Optimus for internal use within Tesla’s facilities are expected as well. Tesla aims to have several thousand Optimus units working in its North American factories by the end of the year once the pilot production line is operational.
Tesla’s goals for production remain extremely lofty - 1 million units per year by 2030. However, they could face some challenges when ramping production.
Key components like the shoulder actuators use specialized permanent and rare-earth magnets, which are currently sourced from China. Due to recent Chinese restrictions on the overseas sale of these magnets, Tesla is seeking an exemption or alternative suppliers. They have not yet looked into modifying the shoulder actuator but will likely do so if they cannot obtain the necessary materials.
Batteries
Batteries are another item that Tesla’s teams have been working on behind the scenes for years now. The second generation of the 4680 - the Cybercell - has been IRA-compliant for some time now. This means that the Cybertruck is eligible for the US Federal EV rebate.
Tesla also achieved the lowest cost-per-kWh of any of its cells with the 4680 battery - and it is potentially one of the cheapest cells being manufactured by any vehicle battery manufacturer at this point. With dry-cathode still being worked on, Tesla may be able to squeeze more optimizations and cost efficiencies from the 4680 cells.
Additionally, Tesla is progressing with its plans for lithium refining and cathode production in the US, both of which are scheduled to commence in 2025. While the company says they’re no longer supply-constrained for non-LFP vehicle batteries, on-shoring production and sourcing critical minerals from nations outside of China will be key.
LFP batteries continue to be supply-constrained, namely for the Tesla Energy division. LFP batteries and their materials are sourced from China. Due to tariffs and limited exports, Tesla can’t obtain enough and is considering potentially building an LFP production facility in North America.
Energy
Tesla’s energy division is still experiencing some of the highest growth of any of its divisions. Year over year, Tesla saw a 154% increase in energy storage deployments, including both Megapack and Powerwall - for a total of 10.4 GWh deployed in just Q1 2025. While deliveries in energy storage remain volatile due to the nature of Megapack installations, Tesla expects growth to continue rapidly in this segment.
Tesla also deployed 1GWh of Powerwall 3 residential storage this quarter, marking its strongest quarter. Powerwall 3 has received positive feedback from customers, many of whom appreciate its new capabilities with its built-in inverter for solar.
Megapack is continuing to see demand increases, currently highlighted by utility-scale Megapack systems, as well as data centers requiring stable power delivery. Megafactory Shanghai is also online now and producing Megapacks - with an annual production capacity of 20GWh today and up to 40GWh in the future. The site has also produced over 100 Megapacks this quarter, which are all awaiting delivery.
There was a lot of interesting news from Tesla’s Q1 2025 Earnings Call, covering everything from FSD and Robotaxi - to the less glamorous but equally important Megapack and Powerwall.
