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.

Tesla eliminated a newly formed marketing team of about 40 employees as part of its global layoffs, Bloomberg reported on Monday morning. On X, Elon Musk said the ads created by the team were “far too generic” adding that they would apply to “any car”.
Exactly. The ads were far too generic – could’ve been any car.
The team was led by Alexander Ingram who joined Tesla in August 2019 as Communication lead for Automotive. After a few different roles connected with content and social media, Ingram was promoted last December to Senior Manager of Global Growth Content. In the new role, he was leading a global team of creatives focused on Tesla's first ads, as well as social media.
Ingram put out some excellent behind-the-scenes videos on Tesla’s technological advancements such as the one below explaining Tesla’s single casting.
Tesla’s Advertisement Strategy
At Tesla’s 2023 annual meeting of shareholders, Elon Musk said that the company would “try a little advertising and see how it goes”. Since then, Tesla ads have been seen in Google search results and on YouTube.
In Tesla’s proxy statement filed last week, it is seen that the automaker has spent around $200,000 on X-advertising through February 2024.
“As part of a multi-platform advertising campaign, Tesla also directly or indirectly purchased advertising on X, which totaled approximately $0.2 million through February 2024”
Bloomberg’s source added that Tesla still has a smaller marketing team in Europe.
Tesla shared on X that it’s ending its current referral program globally by the end of April. It’ll be replaced by a new one, but that is still “a few months away”, according to CEO Elon Musk.
When Musk was asked if the current credits would be lost, Musk responded by saying “No, just that new credits would not be earned until we launch a future referral program.” That means there’ll be a gap of a couple of months when owners will not be able to earn referral credits.
Tesla was always famous for relying on its community to promote its vehicles rather than spending millions (or even billions) in ad campaigns.
Through Tesla’s referral program — which started back in 2015— customers have been earning referral credits by having friends use their referral link when ordering a Tesla product or taking their first demo drive. At the time, it started with a direct $1,000 prize for the referrer but later evolved to a more complex system with different tiers and points.
Prizes have changed a lot over the years
In its latest version, scheduled to end by the end of the month, Tesla models (S, X, and Y), along with Powerwall, solar panels, and solar roofs, are available for purchase using a referral link. In this version, owners can redeem credits from merchandise to software upgrades for their vehicles. They can even redeem credits for several months free of Premium Connectivity or FSD.
Our current referral program benefits will end after April 30 in all markets
Tesla’s first referral program was released in July 2015 where customers who referred new buyers would receive $1,000 for every new Tesla Model S delivered. For those who were able to accrue 5 or 10 referrals for the US automaker, Tesla raised the bar and offered invitations to the opening of its Giga Factories or even a fully loaded Model X.
Over the first 2 years, Tesla significantly increased the value of the prizes and even offered free or discounted Roadsters with enough referrals. However, in 2019, Elon Musk decided to stop amid cost concerns.
The referral program was re-launched in late 2019 offering new buyers free supercharging for a period of time, FSD access, premium connectivity, or $500 off a new vehicle.
What’s Next
Given the considerable gap of “a few months” between the current program and the next one, it is expected that Tesla will bring a new structure with updated awards focused on minimizing Tesla’s cost while increasing the brand’s awareness.
