Tesla registered a new high resolution radar unit with the U.S. Federal Communications Commission (FCC). Tesla's intended use for these radar units is unknown, but it appears they are intended for imaging, similar to how LiDAR uses lasers to map surroundings.
While Tesla's FSD software has used radar in the past, Elon Musk has a rather unfavorable stance on LiDAR. For the purposes of autonomous driving, Musk sees LiDARs as a "fool's errand." Yet, people have been spotting Tesla prototypes with LiDAR sensors since last year.
Tesla files a patent for a high-res radar sensor
The latest instance of Tesla using LiDAR comes from Twitter user @ManuelRToronto who spotted a LiDAR-mounted Tesla in downtown Toronto, only a few weeks after the release of FSD Beta in Canada.
He took a video of the LiDAR-mounted Model Y with manufacturer license plates from California.
There has been no official announcement from Tesla about these LiDAR-mounted vehicles, but it is safe to assume that Tesla will not use LiDAR on any production vehicles.
Tesla is likely using LiDAR to help train their machine learning algorithms, using it as the ground truth when checking for accuracy. Unlike cameras, LiDAR captures extremely accurate 3D depth measurements.
LiDAR could be used to train these algorithms to accurately interpret depth by relying on precise, non-interpretive LiDAR sensors.
Cameras are limited to 2D data combined with computer vision algorithms to interpret 3D depth. The downside to this approach is that it requires a computational process versus having precise 3D depth measurement from a LiDAR sensor.
However, LiDAR sensors are expensive; the benefit of relying solely on cameras is that it makes Teslas much more affordable.
LiDAR can't be the only sensor used in a vehicle since it can only build a wireframe 3D environment. Without cameras it wouldn't be able to read traffic signs, traffic lights or anything that doesn't have depth.
Vehicles with LiDAR also rely on camera data and fuse the two outputs of the two sensors together to build a virtual representation of the real world.
Musk believes that self-driving cars should navigate the world in the same manner as human drivers. Since humans use their eyes and brain to navigate three-dimensional space, cars with cameras and enough computational power should be able to achieve the same thing.
"Humans drive with eyes and biological neural nets, so it makes sense that cameras and silicon neural nets are the only way to achieve a generalized solution to self-driving, " says Elon Musk.
While other self-driving initiatives like Google's Waymo have taken a LiDAR approach, Tesla is outpacing the competition using vision-only, machine learning and the network effect of over 100,000 vehicles in the FSD Beta program.
Tesla's vision-only approach has become smart enough that adding radar data gives the system more information than it needs and disorients the FSD software.
LiDAR and radar may be helpful in training the FSD software, but Tesla wants to avoid using multiple sensors with potentially conflicting perceptions that would overwhelm the system.
With Tesla's recent patent of a high resolution radar, and the recent reported use of LiDAR, it is possible that Tesla's Robotaxi will employ radar and/or LiDAR in order to reach full automation.
Levels of driving automation
Synopsys
Tesla's FSD software could eventually be segmented into consumer and commercial self-driving vehicles with consumer vehicles reaching conditional autonomy (L2/L3) using vision-only and commercial vehicles reaching full autonomy (L4/L5) with the help of radar or potentially even LiDAR sensors.
Commercial robotaxis could even be multi-sensor (cameras, radar, LiDAR), costing much more, while consumer self-driving vehicles would be vision only and more affordable.
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.

Not a Tesla App
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.
Tesla has added the Acceleration Boost option to the Tesla store for owners of the 2024 Model 3 Long Range - specifically owners in Australia and China. Acceleration Boost is an upgrade that provides a significant performance boost, drastically narrowing the performance gap between the Long Range and Performance versions of the same model.
This upgrade will likely become available in Europe, Canada, and the United States in the next few days as Tesla updates its shops globally.
Acceleration Boost
This new Acceleration Boost is retailing for $3,000 AUD, or approximately $2,000 USD. That’s the same price for current owners of older Model 3 or Model Y Long Range vehicles, which all have the option to purchase Acceleration Boost through the shop.
The boost provides improved 0-100km/h (0-60mph) performance, bumping the 2024 Model 3 LR from 4.4s to 3.8s. The 2024 Performance version comes in at a blazing fast 2.9 seconds, so while it isn’t equivalent to just buying a performance variant in the first place, it is still a noticeable and significant upgrade.
Performance variants also come with a different front fascia vent for cooling, performance drive units, sport seats, adaptive suspension, 20-inch wheels, and Track Mode V3. That’s a significant number of additional features in the $10,000 USD price difference between the Long Range and Performance versions.
Should You Buy It?
If you’ve purchased a Long Range model and are itching to go just that little bit faster at every red light, this is the upgrade for you. It previously came with the cost of slightly reducing vehicle range, but the Tesla store doesn’t make a note of reduced range this time around. The 2023 Model 3 and Model Y Long Range models had an efficiency loss of about 5% due to the additional always-available acceleration and cooling.
You could drive in Chill mode to mostly negate that efficiency loss, but what’s the fun in driving in Chill when you just got Acceleration Boost? Anyhow, the shop listing for the 2024 variant doesn’t include this detail, so it's possible Tesla may have worked some more engineering magic.
Overall, if you’ve got the $3,000 AUD burning a hole in your pocket, some Tesla referral credits sitting around, or just want to go faster, it's definitely an upgrade many users find valuable.
