Tesla may have multiple versions of FSD hardware 4.0
@GreenTheOnly/Twitter
Since its introduction, Tesla's Hardware 4 (HW4), the company's most advanced full self-driving computer, has been shrouded in mystery. Renowned Tesla hacker @greentheonly, or Green, has uncovered more details about HW4, providing valuable insight into its technology.
2-SOC Version and Camera Layouts
Green's analysis of firmware samples led to the discovery of the shipping version of HW4, internally referred to as the 2-SOC (System on a Chip) version. This version supports two possible camera layouts: the current one or an expanded one with added surround-view cameras, such as a front bumper camera and two additional side cameras. These cameras can run at a resolution of 2880x1876 and reach up to 45 frames per second. The main and backup cameras have unique specifications, with the vendor yet to be determined.
The new Global Navigation Satellite System (GNSS) is reportedly based on the Teseo V platform, while the radar system connects via Ethernet and operates on an internal IP address of 192.168.90.110.
Initial HW4 Camera Connectors and New Cameras
Initially, Green revealed HW4 with 12 camera connectors, and new cameras were expected to be used in HW4 vehicles. However, the first vehicles with HW4, specifically the Model S and Model X, have the new hardware but do not include the new cameras. As previously reported in our Project Highland article, Tesla plans to add a new camera to the bumper and one more to each side of the vehicle.
Two HW4 Setups and the 3-SOC Version
Green's latest findings show two HW4 setups: one with additional cameras and one without. Additionally, Green's firmware analysis has uncovered the existence of a 3-SOC version in development. The camera layouts for this version remain the same, but the internal deserializing routing differs.
Increased heat output from the GPU in HW4 has possibily led to limitations in its capabilities. The 3-SOC version could potentially address this issue by offering better heat dissipation or paving the way for new hardware. However, the exact purpose and development of the 3-SOC version remain uncertain at this time.
Tesla Semi Truck-related Findings
In another intriguing development, Green's firmware analysis revealed information related to Tesla's Semi truck, with the Battery Management System (BMS) and all three subpacks accessible over an internal ethernet network.
These discoveries by @greentheonly provide a comprehensive understanding of the advanced technology behind Tesla's HW4. As the most advanced full self-driving computer on the market, its potential applications and capabilities are undoubtedly exciting for the automotive industry and consumers.
As Tesla continues to develop and refine its full self-driving technology, it is crucial to address questions about its safety, functionality, and integration with existing systems. The world eagerly awaits further developments in the cutting-edge HW4 and the autonomous driving experience it promises to deliver.

It has been a long wait for FSD for European customers, many of whom paid for the feature years ago on now legacy hardware. While the FSD transfer program has come and gone multiple times, there’s something to be said about having it available in North America, where it can be used, and in Europe or other countries, where it still just remains the same as Enhanced Autopilot (differences between Autopilot, EAP, and FSD).
FSD Transfer is a nice goodwill gesture from Tesla that in theory doesn’t cost them anything. Instead, it keeps customers, especially those who have been waiting for years, loyal and happy. It also incentivizes them to upgrade to a newer Tesla with HW4, where FSD will hopefully be achieved.
In a reply to a post on X, Elon agreed with the suggestion that offering FSD transfers in Europe would be a fair solution for those who have already purchased FSD but can’t use its capabilities.
FSD Transfer directly addresses a growing concern for many long-term European Tesla owners. Thousands of customers purchased the full package, often many years ago, with the expectation that FSD would eventually be capable and approved for use. However, the reality is that FSD, even as an advanced driver assistance system (ADAS), continues to be pushed back in Europe.
Without the transfer program, it's a difficult choice: either throw away your original investment in FSD and pay for the package a second time (FSD price history), or subscribe to it in the future.
Offering FSD transfers is a good way for Tesla to meet them halfway. It's a difficult situation, and one that’s being hindered by processes beyond the control of both the customer and Tesla. However, a transfer helps both parties. Tesla sells another vehicle, and the customer gets to keep FSD.
When Will it Be Available?
Based on how FSD transfers have worked in the past following Elon’s announcements, this feature is likely to become available for a limited time period in the coming days or weeks. If it happens, we should expect an announcement from Tesla Europe on X and emails being sent out to Tesla customers.
Once the program is in place, all you need to do is complete your vehicle purchase and then inform your Tesla sales advisor that you’d like to transfer FSD. You don’t even have to sell or trade in your old Tesla; FSD will simply be removed from it as a feature.
Hopefully, Tesla enables FSD Transfers for everyone, regardless of region. It should be an ongoing offer until at least FSD is approved in the given country or region.
The introductory price for Tesla’s Robotaxi Network has finally been updated. In a post on X, Elon Musk confirmed that the new fare would be rolling out to complement the new Robotaxi geofence expansion.
This change marks the first adjustment to Tesla’s fares since the initial $4.20 launch price 23 days ago. While the price increase may seem significant in terms of percentages, when compared to other options in the ride-hailing area, it is still drastically cheaper.
But the price is now a princely $6.90, as foretold in the prophecy 😂
Robotaxi currently operates on a simple, flat-rate model. The new $6.90 fare gets you a ride to anywhere within the recently expanded geofence.
So far, this is the opposite approach compared to other services, such as Waymo or traditional ride-sharing options like Uber and Lyft. All these services use dynamic pricing based on distance, time of day, and demand. A comparable trip on any one of these services could cost anywhere from $30 to $65, and potentially even higher during peak hours.
That doesn’t even include the tip fees for human drivers either - another win for Robotaxi (can you tip a Robotaxi?).
Even with the adjustment, the flat $6.90 fare remains less than half the price of a typical competing ride, making Robotaxi the most affordable point-to-point transportation option in Austin, aside from mass transit, for now.
A “Maturing” Service
The price change, moving from one meme-worthy number to another, is a sign that Robotaxi is finally graduating from its initial pilot phase. Following the first major expansion of the service area, this adjustment is a logical next step towards finding a more sustainable flat price.
While the new fare is a 65% increase over the old fare, the key takeaway is that it is still far cheaper than other options, and still just as meme-worthy. Tesla is aiming to have its early access riders complete as many rides as possible during these early months, and this pricing is still very reflective of that.
