Tesla Gigafactory 3 substation on track for activation by end of September
Reports from local Chinese news outlets are suggesting that the substation for Tesla’s Gigafactory 3 site in Shanghai is on track to begin operations by the end of September. The update comes amidst news that workers in the site have laid 16.7 km (10 miles) worth of cabling for the facility. With the cabling in place, Gigafactory 3 has taken yet another step closer to its activation.
Similar to Tesla and its construction partner’s other projects in the Gigafactory 3 complex, the buildout of the substation also saw a significant degree of support from the local Shanghai government and its related departments. Barring any delays in its end-of-September target, the activation of Gigafactory 3’s substation could end up taking no more than 159 days, which is about twice as fast as normal.
The completion of the southwest substation is key to the operations of Tesla’s electric car production facility. Once the substation is complete, it will be capable of transmitting power to the rest of the Gigafactory 3 complex, which could, in turn, open the doors for trial Model 3 production activities. Thus, if the substation starts operations in late September, trial production runs of the Model 3 at Gigafactory 3 this month could be plausible.
Recent videos taken of Gigafactory 3 suggests that the buildout of Tesla’s Model 3 and Model Y production site is continuing at an incredibly rapid pace. Preparations seem to be underway to construct even more buildings in the Gigafactory 3 complex. This was highlighted in footage recently taken of the site, which depicted multiple cranes and pile drivers operating south of the general assembly building.
Neither Tesla nor local Chinese news outlets have shared details about the nature of the site’s upcoming buildouts, though statements from workers have indicated that construction activities in the overall complex have entered their second phase. The actual plans for Gigafactory 3’s Phase 2 construction are yet to be announced, though speculations from the EV community suggest that the upcoming buildings could be allotted for the production of electric car drivetrains and battery packs, similar to Gigafactory 1’s activities in Nevada.
Gigafactory 3 is just as important to Tesla as it is for China. The facility stands to benefit the electric car maker as it would open the doors to China’s greater EV market, which has so far been dominated by local carmakers that roll out affordable electric cars. On the other hand, Gigafactory 3 is also an important structure for China, as the facility stands as a strong symbol for the country’s dedication to embracing sustainable transportation. China has aggressive electrification goals, after all, and there are few better ways to emphasize this than to host the auto industry’s most notable EV maker in its shores.

Tesla utilizes its ‘Rave Cave’ for new awesome safety feature
Part of the massive interior overhaul of both the Model 3 “Highland” and Model Y “Juniper” was the addition of interior accent lighting to help bring out the mood of the vehicle, increase the customization of the interior, and to create a unique listening experience.
Tesla is utilizing its ‘Rave Cave’ for an awesome new safety feature that will arrive with the upcoming Spring Update for 2026.
Part of the massive interior overhaul of both the Model 3 “Highland” and Model Y “Juniper” was the addition of interior accent lighting to help bring out the mood of the vehicle, increase the customization of the interior, and to create a unique listening experience.
Tesla added a Sync Lights feature that will strobe the accent strips with the beat of the music.
It is one of the most unique and one of the coolest non-functional features of a Tesla, as it does not improve the driving of the vehicle, but makes it a cool and personal addition to the interior.
However, Tesla is going to take it one step further, as the Rave Cave lights will now be used for blind spot recognition. This feature will be added as the Spring 2026 Update starts to roll out.
A lot of CRAZY new features coming with Tesla’s 2026 Spring Update, including a new FSD app!
– Self-Driving App (AI4 hardware): New app in App Launcher > Self-Driving for one-tap FSD subscriptions, activation guides, and ongoing stats.
– “Hey Grok”: Voice-activated Grok with… https://t.co/ljeYPlq9Qt— TESLARATI (@Teslarati) April 13, 2026
Tesla writes:
“Accent lights now turn red when an object is in your blind spot and your turn signal is engaged, or when an approaching object is detected while parked.”
This neat new safety feature will now increase the likelihood of a driver, who is operating their Tesla manually, of seeing the blind spot warnings that are currently available on the A pillar and on the center touchscreen.
These new alerts will now warn drivers of cross traffic as they back out of a parking space with little to no visibility of what is coming. It is a great new addition that will only increase the safety of the vehicles, while also utilizing something that is already installed in these specific Model 3 and Model Y units.
The Model 3 and Model Y were the central focus of the Spring 2026 Update, especially considering the fact that the Model S and Model X are basically gone, with only a few hundred units left. Additionally, Tesla included new Immersive Sound and Car Visualization for the Model 3 and Model Y specifically in this new update.

Tesla parked 50+ Cybercabs outside its Texas Factory with some crash tested
Dozens of Tesla Cybercabs have been spotted at Giga Texas crash testing facility ahead of launch.
Drone footage captured by longtime Giga Texas observer Joe Tegtmeyer shows over 50 units of Tesla Cybercab at the Austin factory campus, including several units clustered by Tesla’s on-site crash testing facility.
The outbound lot at Gigafactory Texas sits just outside the factory exit and serves as the primary staging area where finished vehicles are held before being loaded onto transport carriers or dispatched for validation testing. On any given day, the lot holds a mix of Model Y and Cybertruck units alongside the growing Tesla Cybercab fleet, as can be seen in the drone footage captured by Joe Tegtmeyer.

Tesla announced its Spring 2026 software update, and it’s the most feature-dense seasonal release the company has put out. The update covers twelve named changes spanning FSD, voice AI, safety lighting, dashcam storage, and pet display customization, among other things.
The centerpiece for owners with AI4 hardware is a redesigned Self-Driving app. The new interface lets owners subscribe to Full Self-Driving with a single tap and view ongoing FSD usage stats directly in the vehicle.
Grok gets its biggest in-car upgrade yet. The update adds a “Hey Grok” hands-free wake word along with location-based reminders, so a driver can now say “remind me to pick up groceries when I get home” without touching the screen. Grok first arrived in vehicles in July 2025, but each update has pushed it closer to genuine daily utility. Musk framed the broader vision clearly at Davos in January, saying Tesla is “really moving into a future that is based on autonomy.”
On safety, the update introduces enhanced blind spot warning lights that integrate directly with the cabin’s ambient lighting, building on the blind spot door warning that arrived in update 2026.8.
Dog Mode has been renamed Pet Mode and now lets owners choose a dog, cat, or hedgehog icon and add their pet’s name to the display.
Dashcam retention now extends up to 24 hours, up from the previous one-hour rolling loop, with a permanent save option for any clip. Weather maps now show rain and snow with better color differentiation and include the past hour of precipitation data along the route.
Tesla has now established a clear rhythm of two major OTA pushes per year. As with last year’s Spring update, that cycle started taking shape in 2025 with adaptive headlights and trunk customization. The 2025 Holiday Update then added Grok to the vehicle for the first time. This Spring follows that structure: the Holiday update introduces new architecture, and the Spring update broadens it across the fleet.
Two notable features still did not make it. IFTTT automations, which launched in China earlier this year, were held back from this North American release for unknown reasons, and Apple CarPlay remains absent, reportedly still delayed by iOS 26 and Apple Maps compatibility issues.
Below is the full list of feature updates released by Tesla.
