Tesla recently showed off Giga Small Haus, an interesting new display project hosted at Giga Berlin. The small new house is located just outside the main entrance of Tesla’s Giga Berlin factory, with a Quicksilver Model Y parked inside.
Giga Small Haus is powered only by solar and Powerwall 3 - disconnected from the local grid and from Giga Berlin itself. It serves as a live demonstration of Tesla Solar and Tesla’s Powerwall battery backup.
Giga Small Haus
The centerpiece of the display is a Model Y in Quicksilver - a beautiful pick for a beautifully lit house. However, that’s not the real focus here - it's the Powerwall and Gateway on the wall.
The Powerwall is the focus of Giga Small Haus, and there’s a display with some additional information on the wall. Part of the display also includes a screen that displays the current output of the Powerwall itself versus the consumption of Giga Small Haus, as well as the input from solar.

The text on the exhibit is divided into several sections. Here’s a translated and edited version of what we can see from Tesla’s images. Some additional text is obscured. If someone visits Giga Small Haus, let us know.
Powerwall
Powerwall is a home battery system that stores energy from solar panels, the electrical grid, or during off-peak hours and powers your home during the day or during a power outage.
With Powerwall, you can use self-generated solar energy during the day and night, thus avoiding high electricity costs. You can also store excess energy produced during sunny periods for use during times of low production or power outages.
Key Features
Energy Storage: Powerwall stores excess energy from solar panels or the grid for later use or during power outages.
Backup Power: In the event of a power outage, Powerwall automatically switches to battery power to ensure continuous power supply.
Integration: Powerwall can be seamlessly integrated with existing solar systems and other power sources.
Scalability: Multiple Powerwalls can be installed to meet higher energy storage needs.
Smart Energy Management: Powerwall works with Tesla's software to optimize energy consumption and reduce costs.
How Powerwall Works
Storage: During the day, when solar panels produce more energy than needed, the excess is stored in Powerwall.
Usage: At night or during times of low solar production, the stored energy is used to power the home, reducing reliance on the grid.
Backup: During a power outage, Powerwall automatically provides power to critical circuits, ensuring continuous operation of essential appliances.
Benefits
Cost Savings: By storing and using solar energy, you can reduce your electricity bills.
Reliability: Provides backup power during outages, ensuring your home remains powered.
Sustainability: Promotes the use of renewable energy by storing excess solar production for later use.
Overall, Giga Small Haus is an interesting real-life demo of what Powerwall and Solar can accomplish. It would be neat if Tesla built more of these displays - perhaps near major Delivery and Service Centers and at Giga Texas, Fremont, Giga Shanghai, and other facilities. Many Tesla owners have yet to learn about and experience some of Tesla’s Energy products.

With most vehicles moving on to Tesla’s 2025.14 Spring Update, we’re now taking a look at all the undocumented features that were discovered during Tesla’s 2025.8 update.
While these features tend to be smaller in nature, some of them are just as valuable as the features outlined in Tesla’s release notes in the vehicle.
This update includes changes such as improvements to maps, trip meters, and Rainbow Road. Let’s take a look at all the undocumented features in Tesla’s 2025.8 software update.
New Map Icons
Not a Tesla App
Icons on the map are being redesigned to be rounder and easier to see. They now feature a white border to make them pop out against a colorful background, which is especially better when using satellite views.
This feature started rolling out slowly but should now be available to everyone.
Trips & Odometer
Not a Tesla App
The Trips display has been improved to show more precise information, and a new metric has been added.
More Precision: The trip meters will now show values with a tenths place when they’re under a certain value. That means that the Current Drive and Since Last Charge trip meters will now show a fractional kWh and a mile. This is especially useful for Current Drive.
The Current Drive meter is automatically reset when your vehicle comes out of park so that it can track your current drive, while the Since Last Charge meter automatically resets after a charging session completes.
More Data: In addition to added precision, the Current Drive now features a new data point. kWh is now shown for the current drive, just like the other trip meters. Previously, the Current Drive showed minutes instead of kWh -- it now features both.
These changes affect the Trips widget in the Model 3, Model Y and Cybertruck. While the added precision is also added to all vehicles under Controls > Trips, the new kWh metric for the Current Drive is only displayed in the small widget.
Additional Tool Tips
Not a Tesla App
Tesla has added some additional tips to the screen that show up in certain cases. For example, if you’re playing audio over Bluetooth, Tesla will suggest that you use their built-in music apps instead of streaming through your phone.
Destination Charging
Not a Tesla App
Destination charging icons are now visible on the map when you have Points of Interest enabled. You can enable Points of Interest by tapping on the map and choosing the Points of Interest icon on the right side near the satellite imagery icon.
Some destination chargers may charge a fee, while others may be open to the public or exclusive to paying customers.
Navigation Improvements
Not a Tesla App
If you're using Tesla's navigation system with voice guidance enabled, the spoken directions will now stop immediately when you end the trip. Previously, the spoken directions would continue being played until the phrase was completed.
Improved Rainbow Road
Not a Tesla App
The rainbow road feature has been greatly improved in this update with FSD. Rainbow road, which can be enabled in the Toybox app, now changes the vehicle's path when on Autopilot from a blue path to a rainbow one.
Previously, Tesla had to overlay the blue path on top of the rainbow colors because rainbow road didn’t support all the features of the path, such as showing chevrons when slowing down rapidly.
With this update, the rainbow path now incorporates all the same features as the blue path when FSD is active.
In addition, if you start Rainbow Road by tapping the right stalk four times, audio will play. Unfortunately, the sound couldn’t be stopped until it was completed before, but with this update, you can now stop the audio by reducing the volume with the left scroll wheel.
Additional Transparency Effects
Not a Tesla App
On Intel vehicles, several modules didn't include a transparency effect. This was primarily due to Intel cars not using the blur effect since it could slow down the infotainment unit.
With this update, Tesla has enabled the transparency effect across a set of modules. Notably, this fixes the issue when using full-screen visualizations where the music player had transparency, but the navigation module on the right did not.
Transparency has also been added to other modules that are displayed over the map, such as the list of Superchargers, destinations, search results, and the ETA / End Trip module displayed at the bottom.
Note: Due to the lack of the blur effect on Intel due to performance reasons, these changes could make some text more difficult to read.
No Phone Key Graphic
Not a Tesla App
The graphic that's displayed in the vehicle when it doesn't detect a phone key has been updated. Tapping on the blue text at the bottom displays the old animation showing you where to tap a key card.
Bluetooth Player
Not a Tesla App
The Bluetooth app typically only displays the connected devices and a button to connect a new device. There was a lot of white space, since there wasn’t much other information to display.
With this update, Tesla is making it easier to jump to another source by displaying available music streaming services underneath the connected Bluetooth device.
Tapping a music service will jump to the selected service.

Next Update
Tesla’s next update is the 2025.14 Spring Update, which has now rolled out to more than half of the Tesla fleet. If you’re still waiting for it, rest assured that you should be updated soon. If you’ve already updated, be sure to check out the undocumented features already found in the 2025.14 update.
Tesla has issued a strong denial in response to a Wall Street Journal report (Paywall) which claimed that Tesla’s Board of Directors had initiated a search for a new CEO.
In a statement posted directly on Tesla’s X account, Board Chair Robyn Denholm denied the report unequivocally. As per the statement, Tesla’s board did not reach out to recruiting firms in search of a new CEO.
Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company.
This is absolutely false (and this was communicated to the media before the report was published).
The statement reaffirmed the board’s position on Tesla’s current leadership and that the board is highly confident in Elon’s ability to continue executing Tesla’s plans and future growth.
This confidence behind Elon follows his recent statements made during the Q1 2025 Earnings Call that he would be stepping back from the Department of Government Efficiency (DOGE) in the coming days and significantly reducing time spent there. Instead, he would be returning to focus on Tesla’s operations and the upcoming deployment of Robotaxi.
Shortly after the denial was posted, Elon Musk also commented on the report, specifically tagging the Wall Street Journal and criticizing their handling of the report.
It is an EXTREMELY BAD BREACH OF ETHICS that the @WSJ would publish a DELIBERATELY FALSE ARTICLE and fail to include an unequivocal denial beforehand by the Tesla board of directors! https://t.co/9xdypLGg3c
We’re glad to see Tesla and Elon set the matter straight, but there could have been a better way to spread this message and maybe even prevent the report from WSJ from going out.
We recently published an opinion piece on why Tesla needs its PR team back, and this specific incident is a good example. Relying solely on platforms like X for critical corporate communications - and in this case, late at night (1 AM EST), with limited reach outside the existing follower base seems like an ineffective way of communicating important company information.
We’d love to see Tesla really put some thought into managing its image, as it seems that several recent reports from major financial news organizations have apparently been wrong.
Either way, the board’s stance is clear - there is no active search underway, and Elon has the full backing and support of the board to lead Tesla toward the future.
