Tesla requested more time for details to be kept confidential, and in doing so, everyone now knows something is up. A document dated November 18, 2022, appeared on Twitter on December 6. It’s from Tesla Inc. and addressed to the Federal Communications Commission. In the brief letter, Certification Engineer Cindy Li requests a 60-day extension of a previous agreement to keep a device secret. This mysterious letter set the Tesla sphere on fire with speculation to find out what is the secret device.
All we know from the letter is that model number 1541584 includes a user manual, internal photos, external photos, and test setup photos. Whatever this device is, it was going to be made public by the FCC on December 7, 2022. Tesla asked for an extension because the device will not be ready until mid-January 2023. The company wants to “avoid any unnecessary disclosure and competitive harm before our product launch…”
The poster of the letter, Twitter user @Taka87 reached out to well-known Tesla hacker @greentheonly, for some insight. The response: … something potentially major planned for mid-January which is just a bit over a month away... Like something that coincides with a sensor suite change.
That opens the door for the return of radar, which was removed last year and/or ultrasonic sensors, which Tesla just scrapped in October when it made the call to go completely with Tesla Vision. At that time, Tesla said in a statement: With today's software, this approach gives Autopilot high-definition spatial positioning, longer range visibility and the ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time.
There has also been a lot of speculation about HW4, where a high-resolution radar is believed to be part of the full self-driving sensor suite. HW4 goes as far back as the 2021 A.I. Day when Elon Musk said a new FSD computer would come out with the Cybertruck. This upgrade is now reportedly being developed by the Taiwan Semiconductor Manufacturing Company Limited (TSMC). It is expected to be much more powerful than the current hardware by as much as four times.
Elon has also previously commented on HD radar, saying "A very high-resolution radar would be better than pure vision, but such a radar does not exist. I mean vision with high-res radar would be better than pure vision."
An unidentified part, closely resembling a new radar was found on Tesla's Parts Catalog back in September by @GreenTheOnly. This mysterious item was marked but suspiciously not given a name, a part number or a description. However, given Green's experience with the inner workings of these vehicles, Green believes it is a new Tesla radar. In a follow-up tweet, he doubled down on his stance, saying the part matches the high-resolution radar Tesla registered with the U.S. Federal Communications Commission in June.
Fans recently spotted multiple Model 3 vehicles that had parts of the front and rear of the vehicle covered up. If Tesla is planning to add HD radar or change some of the vehicle's sensor suite, these vehicles may be testing exactly this.

It was a rainy April 1st when a news-searching author went on a delve into the depths of April Fools to find fact from falsehood. And while we found a lot of fantastic jokes, we also found some good ideas.
So, with a shoutout to MarcoRP on X, whose April Fool’s Joke gave us a good run for our money for a couple of minutes, we thought to ourselves - what would a Cybercab Charging Station / Cleaning Hub really look like?
Cybercab Wireless Charging Sites
Now, before continuing, we’d like to point out that the image up top is a joke from Marco - it isn’t an accurate or real site map submission from Tesla. However, it gave us the impetus to think critically about what is required for a Robotaxi fleet, based primarily on the Cybercab, to be able to service a city.
Requirements
Tesla will likely need to charge a small fleet of Cybercabs at a single time and in a single place. That means that the site needs to be large enough to cover a major metro area while also still being compact enough to not cost too much money to build out.
In addition, we need to factor in charge times. The Cybercab is likely to launch with a battery around 50 kWh, which will result in a range of approximately 300 miles. With that much range, the average Cybercab may not need to charge more than once or at all during daytime shifts, so instead, most of the vehicles will charge overnight.

Math and Charge Times
The overnight charging means that most of these vehicles could be charged slowly. When we did some back-of-the-napkin math last year, we determined that Tesla’s wireless charger will likely peak around 17 kW (for comparison, Tesla’s Wall Connector at 32 amps charges at about 7 kW). If we scale Tesla’s wireless charger down slightly to 10 kW, accounting for some energy loss and the potential size of the site, that means a Cybercab will be able to charge in about 5 hours.
Tesla’s upcoming V4 Supercharger unit can currently handle 1.5MW per cabinet, but this slower-speed charging is A/C, not DC, which means there is a step-down loss of about 3-5%. Let’s make that a comfortable 10% for any other overages, but we can estimate around 1.35MW of power. That 1.3MW will easily handle charging up to 100 Cybercabs at once - all wirelessly, using Tesla’s unique beam-forming and beam-steering technology to keep efficiency high at every single stall.
Within about 5 hours, a whole fleet of 100 Cybercabs could be charged overnight when electricity rates are cheaper and still be out in time for the morning commute.
While this is all just hypothetical, it really does make sense that Tesla will be establishing these sites that won’t require much space or a ton of energy.
Tesla recently curtained off a large section of the parking garage at Giga Texas, as well as some of their chargers on the eastern end of the facility, leading us to believe they may just be testing this at scale internally.
There’s a lot to look forward to with Tesla’s V4 Supercharger deployment coming this year and with Robotaxi launching in just a couple of months.
Tesla released its Q1 2025 delivery and production numbers this morning, reporting 336,681 vehicles delivered and 362,615 produced—marking the company’s weakest quarter since 2022. Deliveries declined 13% year-over-year and fell well short of Wall Street estimates, which ranged from 360,000 to 370,000. Some analysts had forecast as many as 407,000 units.
Despite the shortfall, Tesla stock is actually up about 4% this morning, not only suggesting the market had already priced in weaker performance, but that this may be seen as the low point for the company. Tesla began delivering its refreshed Model Y in March, and production across all four Gigafactories was impacted by several weeks of downtime as Tesla retooled lines to accommodate the newer model. However, there’s no doubt that there is some brand impact from Elon Musk.
Comparing Numbers
Most of the deliveries—323,800 units—came from the Model 3 and Model Y lineup, while the “Other Models” category (including the Cybertruck, Model S, and Model X) accounted for 12,881 deliveries. That’s a 31% drop for Model 3/Y and a sharper 45% drop for the Other Models category compared to the previous quarter. However, comparing it to a more applicable Q1 2024, these numbers are only down about 13% for the Model 3/Y and down about 24% for the Model S/X and Cybertruck.
In terms of production, Tesla built 345,454 Model 3/Y vehicles and 17,161 from its “Other Models” line. The company attributed the production drop to the Model Y changeover but said the ramp is “going well.” This still leaves a large gap between production and delivery numbers, although they may not be as large as many had feared.

Cybertruck
One major weak point in Tesla’s numbers seems to be Cybertruck deliveries. While Tesla previously expected the Cybertruck to sell more than 250k units per year, we’re already seeing a decline in numbers. This is likely due to several factors, including the higher-than-expected price point of the truck, the unavailability of the RWD model, and the Cybertruck’s polarizing design, which may attract unwanted attention right now.
While the Cybertruck was ramping up production in 2024, making the lower numbers reasonable, the deliveries for Q1 2025 dropped drastically compared to the previous quarter. Cybertruck deliveries are estimated to be in the 5- 6k unit range for the quarter.
The good news to take away here is that the Single Motor variant of the Cybertruck appears to be nearing release. The price of the RWD version is expected to be about $60k USD before any incentives.
Q1 Earnings Call
Tesla announced their quarterly numbers this morning and posted on social media that they’ll live stream their Earnings Call on April 22nd.
This post was later edited to change “Q1 Earnings Call” to “Q1 Company Update.” It’s not clear whether there’s any significance in this change, but it could mean that Tesla has more to announce during the call.
The Company Update will occur on April 22nd at 2:30 PM PT / 5:30 PM ET. The standard Q&A session with executives and Musk is expected to follow the release of additional financial results for the quarter.
Tesla is set to launch its long-awaited Robotaxi service in June, and a cheaper, mass-market model is also planned for this year. With delivery numbers coming in soft and the refreshed Model Y just hitting the road, all eyes will be on forward-looking commentary during the update.
