New images and details surrounding Tesla’s most robust self-driving computer, or Hardware 4 (HW4), were shown today, revealing additional cameras, a reintroduction of potential radar systems, and more.
Tesla released some details about HW4 during last year’s AI Day event. Still, additional specifications were revealed today by Greentheonly, a Tesla hacker who said the computer came from a Model X vehicle. Green said that Tesla has already started building vehicles with the new computer, but they are not yet being delivered.
I am sure you are all eager to know more about HW4, so I am going to show you the refreshed car computer from a Model X. Just don’t tell anybody you saw it, because it’s really a secret still.

Right off the bat, green confirms what CEO Elon Musk said during the most recent earnings call: retrofits of HW4 into older vehicles will not be possible. While green shows the form factor of the new computer is completely different than past ones, even the most recent applications that were installed in Plaid vehicles, the new HW4 is simply not compatible.
Musk said during the Q4 Earnings Call in late January:
“But it is the cost and difficulty of retrofitting Hardware 3 with Hardware 4 is quite significant. So it would not be, I think, economically feasible to do so.”
Many of the specifics of HW4 are extremely technical, but it appears Tesla aimed to simplify the infotainment system to void a GPU daughterboard. The entire unit is smaller and sleeker, but the RAM, NVMe (nonvolatile memory express), CPU, and GPU are all identical to past units.
Green adds:
“A lot less improvement than many hoped for. Still Samsung Exynos-IP based. Bumped CPU cores from 12 to 20 (5 clusters of 4 cores each), maxing at 2.35GHz, idle at 1.37GHz Number of TRIP cores increased from 2 to 3, 2.2GHz max freq All x2 since there are two SoCs per board.”

Perhaps one of the most notable differences are there are now 12 “fully-populated camera connectors,” with one being utilized as a spare. The cameras are also labeled, and some seem to indicate that cameras will be added to the front and rear bumpers. “There’s a huge blindspot up front on legacy cars up front,” green notes.
What’s SVC you might wonder? According to EPC, SVC is bumper. So I’d guess these are bumper cameras. There’s a huge blindspot upfront on legacy cars up front (welcome to the legacy camp, Plaid owners!), so front bumper camera and two in the (rear?) bumper corners for x-traffic pic.twitter.com/sixzNo7qII

This would make sense, considering Teslas currently utilize eight cameras, with the additional three connectors making way for the two rear and one front camera that will be added with the new hardware.
Another interesting detail found by green was Phoenix radar, which is a rumored 4-dimensional radar that will help extend current reach by double. Tesla wanted to move away from radar, opting for a completely camera-based approach, which it did with the introduction of its Vision model.
Musk said during the Q1 2021 Earnings Call:
“When your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes in the back of your head, beside your head, and has three eyes of different focal distances looking forward. This is — and processing it at a speed that is superhuman. There’s no question in my mind that with a pure vision solution, we can make a car that is dramatically safer than the average person.”
However, radar and a radar heater were both seen in vehicle coding. The Phoenix radar appears to be a type of forward radar that will be installed in HW4 vehicles.
Perhaps more details will be shed regarding HW4 in the coming weeks, especially as Tesla’s Investor Day is approaching and will take place on March 1.

Tesla Germany’s “Giga Train’s” improved service gets rave reviews
As per recent reports, Tesla’s free “train”Giga Train” service will increase its daily trips to six starting this week.
Tesla has expanded its employee shuttle service from Berlin Ostbahnhof East Station to the Gigafactory Berlin-Brandenburg. As per recent reports, Tesla’s free “train”Giga Train” service has increased its daily trips to six starting this week.
The service has so far received positive reviews from the facility’s employees, some of whom noted that the upgraded shuttle train has reduced their travel time by a notable margin.
Giga Berlin’s expanded shuttle service
As noted in a rbb24 report, Giga Berlin’s free shuttle train now operates six times daily, up from one previously. The service also goes directly to the Model Y production facility without stopping at other stations. Tesla employee Dené Schunck described the service to rbb24 in a comment: “The shuttle goes directly to the factory site, without any transfers, which reduces the commute time for our employees by almost half,” Schunck stated.
Operated by Ostdeutsche Eisenbahngesellschaft (Odeg) after switching from Niederbarnimer Eisenbahn (NEB), Giga Berlin’s shuttle train, which also stops at Ostkreuz and Erkner, remains free for all riders, including non-Tesla employees. It has been fully funded by Tesla Germany since September 2023.
Employees praised the changes: One Giga Berlin worker stated that it “definitely makes the journey easier” because employees “used to need two hours for the round trip from Berlin, but now it’s significantly faster.”
Tesla Germany’s previous comments
In late 2025, reports emerged stating that Tesla Germany will be expanding its shuttle train service by adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg. In a comment, Tesla Germany stated that the updated service would mirror the shift changes for the Model Y factory’s employees.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany noted.
At the time, Tesla Germany also stated that despite construction being done at Fangschleuse and Köpenick stations, the route of the Giga Train has been optimized to maintain a predictable 35-minute travel time. This should provide Tesla Germany’s employees with a convenient way to travel to and from Giga Berlin.

Tesla stands to gain from Elon Musk’s rekindled friendship with President Trump
“He’s 80% super genius and 20% he makes mistakes, but he’s a good guy. He’s a well-meaning person.”
Tesla CEO Elon Musk and President Donald Trump are back in each other’s good graces, and after a lengthy period where the two were at odds, the pair seemed to make up back in September.
The two were spotted at dinner at Trump’s Mar-a-Lago estate in West Palm Beach over the weekend, which was followed by a press conference on Air Force One, where the President called Musk, “great.”
He continued:
“He’s 80% super genius and 20% he makes mistakes, but he’s a good guy. He’s a well-meaning person.”
Musk previously had a position in Trump’s White House, as he was in charge of reducing government spending and waste by leading the Department of Government Efficiency (DOGE). Musk stepped back from his role in the government last year to focus on Tesla and SpaceX, as well as other projects.

However, Musk, back in Trump’s good graces, stands to get some assistance for Tesla from the White House moving forward, especially as he and the President are back to being friends and allies.
Reduced Scrutiny from a Regulatory Standpoint
Tesla has been the subject of several National Highway Traffic Safety Administration (NHTSA) probes, including ones that dive into Autopilot and Full Self-Driving and incidents involving the two.
Trump has already initiated a more relaxed environment for autonomous vehicle oversight. Last January, he proposed a voluntary framework system for self-driving vehicles, which reduced barriers for companies involved with autonomy.
In April, he relaxed crash reporting and exemptions for autonomous vehicles, creating a clearer pathway for companies to innovate and easing compliance burdens.
In September, Transportation Secretary Sean P. Duffy led efforts to update FMVSS, eliminating redundant human-driver requirements. This aimed to create a single national standard, boosting deployment and eliminating much of the bureaucracy that stalls innovation.
Favorable Autonomous Vehicle Framework
Some of the moves that were mentioned previously will assist Tesla in rolling out its Robotaxi network across the country, and although it currently has to go through the process on a state-level, things could become easier for Tesla and other companies exploring self-driving vehicles.
Musk could have a direct line to Trump that would help create fewer regulatory barriers for the companies involved in developing autonomous vehicles, which would directly benefit Tesla, but also its competitors like Waymo.
Protection from International Competition via Trade Policies
It is no secret that the President is focused on domesticating manufacturing, AI efforts, and everything in between. This is enforced by the tariffs the White House enforced last year, which have prioritized U.S.-based companies.
This could shield Tesla from potential foreign competitors, especially ones like BYD, which have been formidable opponents.
Overall, these gains stem from a more aligned political environment, where Musk’s influence could prioritize deregulation over enforcement; this leads to more innovation and relaxed regulations, but there are some risks. However, outcomes are dependent on the depth of President Trump and Musk’s reconciliation.
Long-term benefits to Tesla would require concrete policy actions.

Tesla FSD earns high praise in South Korea’s real-world autonomous driving test
As per the Korea Expressway Corporation’s report, the FSD test was conducted on December 15, 2025, from 10 a.m. to 6 p.m.
Tesla’s Full Self-Driving (FSD) has received a bullish assessment from the Korea Expressway Corporation following a real-world autonomous highway driving test.
A report of the test, shared on Naver Cafe, showed high praise for the system’s safety, capabilities, smooth maneuvers, and confidence.
South Korean highway test
As per the Korea Expressway Corporation’s report, the FSD test was conducted on December 15, 2025, from 10 a.m. to 6 p.m. Four people were in the Tesla that was tested, including the head of the mobility department. All four FSD driving modes were tested, from “Sloth” to “Mad Max.”
To test FSD’s performance, the system was tasked to operate on highways such as Gyeongbu, Cheonan, and Cheonan-Nonsan, as well as city areas in Dongtan New Town, Sejong Special City, and Daejeon Metropolitan City, among others.
Since FSD is only available for the Tesla Model S and Model X that are imported to South Korea from the United States, the system was not tested in a Model 3 or Model Y, which comprise the majority of Teslas on the country’s roads today.
Highway test results
Results showed FSD performing well, both in inner-city roads and on highways. In inner city roads, the testers noted that FSD was capable of autonomous driving at a level that already exceeds that of general human drivers, except in very few areas, such as unprotected left turns and work zone intersections.
In highways, the testers described FSD’s performance as “excellent,” though the system still showed frequent cases of violations in local bus lanes and max speed limit rules. These, however, could hopefully be addressed by Tesla in a future FSD update without many issues. The testers also noted that in some parts of the test, FSD seemed to be driving autonomously in accordance with traffic flow rather than strict traffic rules.
