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.

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 Model Y reclaims elusive sales title in competitive market
As more EVs have entered the market and some at better prices, Tesla’s Model Y has been put up against some very attractive options.
The Tesla Model Y reclaimed an elusive sales title in one of the most competitive markets it is in, outpacing key rivals and formidable competitors to regain the crown it once was a shoe-in for.
As more EVs have entered the market and some at better prices, Tesla’s Model Y has been put up against some very attractive options.
This is especially prudent in Europe and China, where domestic car companies have been offering attractive and cheap EVs as Tesla alternatives.
However, in September, the Model Y was able to battle back and take over the top sales spot for EVs in Europe.
In September, it had 25,938 sales, and although it was an 8.6 percent decrease compared to the same month in 2024, it was enough to be labeled the best-selling car in the European market, Automotive News reported.
500-mile test proves why Tesla Model Y still humiliates rivals in Europe
There are four vehicles that have been atop the European EV sales rankings for any given month this year: the Renault Clio, which has three titles, the Dacia Sandero, which has won four monthly sales titles, and the Volkswagen T-Roc, which was the best-selling car in the market in August.
The Clio captured the number-two spot in September with 20,146 sales.
Despite a strong September showing for the Model Y, which was its first monthly sales crown of the year, the vehicle has not been a top-three EV in Europe this year. That is still led by the Sandero, Clio, and T-Roc.
Despite that, Tesla’s Model Y is still likely to be one of the best-selling vehicles in the world, if not the best, for the year.
In the United States, it has dominated EV sales charts and has been one of the most popular cars in the region. The same goes for China, where the Model Y has more competition than in Europe, but is so attractive because of its premium look and feel, as well as its tech offerings.
The Model Y has been the best-selling car globally for the past two years, outpacing widely popular gas and EV models from around the world.
Tesla also just finished up its best three-month sales period in its history, delivering just shy of half a million vehicles from July to September.
A Tesla captured video of a crashing plane on an Oklahoma highway, as a shocking video shows a small aircraft coming across a local roadway, with various cars ducking to avoid it.
On October 23, an Oklahoma National Guard OA-1K Skyraider II turboprop plane crashed during a training mission after an engine failure. Both crew members escaped unharmed, but they were not the only ones at risk of injury.
A Tesla Dashcam video shared by a friend of the car’s owner shows the vehicle narrowly avoiding an impact with the plane, swerving left, then back onto its side of the road. It appears to be a serious miracle:
WOW! Tesla full self driving dodges a freaking plane falling out of the sky! @Tesla fsd for the win! @elonmusk pic.twitter.com/vTVxuLPsHg

David Bellow, the person who posted the video of the Tesla avoiding the plane, claims it was Full Self-Driving that performed the maneuver, but it is not confirmed. This is what he said:
This wasn’t me my friend sent me the video from Matthew Topchian it was his Tesla. I’ll see if my friend can reach out and get more details of what fsd version! I personally had a video of my Tesla maneuvering between two bunnies at night on the road so I fully believe this to be…

There are a few hints that suggest it could be Tesla’s Full Self-Driving suite, but it is important to note that neither the company, the driver, nor the friend has confirmed this.
The first hint is the vehicle’s maneuver and subsequent reaction. The car suddenly swerves to the left, which any human would do, but how the vehicle continues to travel as if nothing had happened seems to solidify the idea that FSD could have been involved in avoiding the plane.
Nevertheless, this does not confirm that FSD was in control.
My Tesla did this on FSD (Supervised) v14.1 and the internet went crazy
Most people would likely have stopped in their tracks after avoiding an aircraft while driving.
However, this is not enough proof to definitively say FSD was responsible for the avoidance.
Additionally, the “Jump to Event” button is activated in the video, suggesting that FSD was in control. The vehicle gives this option when something major has occurred, including human intervention.
Regardless of whether the car was on FSD or was controlled manually, it is pretty crazy to have this piece of dashcam footage.

Tesla Full Self-Driving got a minor feature that’s a massive improvement
“Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.”
Tesla’s Full Self-Driving suite seems to get better with every single release. However, it is also making it more seamless and easier than ever to use for passenger travel, thanks to a recent feature that has flown under the radar.
Tesla started rolling out its v14 iteration of the Full Self-Driving suite a few weeks ago to Early Access Program (EAP) members, and it finally started making its way to the public for the first time earlier this week.
Tesla Full Self-Driving v14.1 first impressions: Robotaxi-like features arrive
The wide rollout of Tesla v14.1.3 was long-awaited, as its capabilities were flexed by the handful of people lucky to have it. However, those sitting with v13.2.9 were still eager to get to their hands on the new FSD version, especially considering it came with a lot of cool upgrades.
One of which is flying under the radar and not getting as much attention as it should. Although it is a minor feature change from v13, Tesla has made FSD more seamless than ever with a simple fix that it started utilizing with v14.
With v14.1.1, Tesla started rolling out the removal of the “Brake Confirm” feature, which required drivers to touch the brake to activate Full Self-Driving. This is now an optional feature, as it now is defaulted to the off position by the car.
The release notes for the feature state:
“Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.
You can enable Brake Confirm in Autopilot > Brake Confirm.”

Simply put, you no longer need to touch the brake to confirm your intention to use Full Self-Driving, which is a small but very effective fix.
It makes your car much more active in terms of overall activation, and it is definitely a quicker and more streamlined departure from your current location than ever before.
Here’s a good look at how quick it is:
@teslarati With Tesla Full Self-Driving v14, there is no delay when you start FSD. Press “Start Self-Driving” and you’re on your way #fyp #viral #tesla #teslafsd #fsdv14 ♬ original sound – TESLARATI
The feature is small, but it is very noticeable with your first uses of FSD v14. Eventually, it will become even more streamlined as Tesla solves self-driving and autonomy, as it will require zero human intervention to get started, which means the “Start Self-Driving” button will also be removed.
