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.

According to Tesla Service, the game was only under a “temporary suspension.” The service representative goes on to state: “Indeed, this game is currently suspended, it will be re-integrated soon.”
Early last year, Tesla added Sonic to vehicles that did not have data-capable USB ports in the front via the glovebox. Version 2022.28.1 release notes read, “A game controller plugged into the glovebox USB port is required.”
Sonic the Hedgehog is a platform video game that was released in 1991 by Sega for their Genesis gaming system. Players control a blue hedgehog, named Sonic, to run at fast speeds on a mission to overtake Dr. Robotnik, a mad scientist who has locked away animals inside robot bodies while chasing after the Chaos Emeralds.
The removal of Sonic the Hedgehog is still unclear, but we’re speculating that it had to do with a bug or the license expiring.
Tesla also added Steam to a few of its vehicles, which signals that they may be transitioning away from adding more games. Instead, they’ll rely on Steam’s vast catalog of games for users to enjoy. Tesla may simply transition into making sure Steam is running smoothly on its operating system.
New information is leaked about Tesla's upcoming hardware 4.0 suite
@ChrisZheng001
We now have new information regarding Tesla's updated cameras that will be used in Hardware 4.0. Twitter user @ChrisZheng001, who has ties with the Tesla supply chain in China, posted three images that appear to be camera configurations. While the information in the picture is limited, there is enough text to uncover what may be in development at Tesla.
Three Cameras to Two
The front-facing cameras will be reduced to two
@ChrisZheng001
Perhaps the biggest change comes to the trio of cameras that make up the forward-facing view for the Autopilot system. The translation appears to state that Tesla will be reducing its three front-facing cameras down to two and all cameras, including the interior camera, will be upgraded to 'AP4' cameras. The newer cameras are expected to have a much higher resolution in addition to other improvements such as LED flicker mitigation.
The only information provided by @ChrisZheng001 in the post is: The Autopilot HW 4.0 front camera will be reduced to two Cz (because) of the significant increase in both pixel density and field of view.
In November of 2022, it was revealed that a Tesla supplier was producing 5-megapixel cameras. The current cameras are 1.2 megapixels. So, while the number of cameras is being reduced, Tesla Vision will actually improve.
Fans for Forward Facing Cameras
The front-facing cameras will feature a fan to help with condensation
@ChrisZheng001
That leads to the next change. The housing size doesn’t appear to change, just what is in it. According to the document, and again using Google translate, it states: the shape of the black border at the position of the front camera has changed/added a camera fan.
By that wording, it sounds like the new housing will include a fan, likely to prevent condensation buildup. However, it seems open for change with a window for feedback and further evaluation.
B-Pillar Changes
B-pillar cameras will gain a heater in addition to a new camera opening
@ChrisZheng001
There is one more picture. The text reads: B-pillar exterior trim. B-pillar exterior panel camera change, opening shape change, new camera heating device. Inspection station: final care exterior decoration inspection appearance; heating function will be evaluated after project feedback.
There is not much to figure out there. Tesla appears to be adding a heating device to keep the B-pillar cameras clear and changing the shape of the opening. That could be due to the size of the new cameras or the field of view they require.
It’s widely speculated that a new high-resolution radar unit is in the works. That radar combined with these high-powered cameras means Tesla’s already incredible Autopilot system will only improve.
