Tesla hacker and Twitter user @greentheonly has speculated that it won’t be possible to retrofit current MCU 2 (Media Control Unit) Teslas employing Intel chips with the new and improved Ryzen-based processor that is used in MCU 3.
In an up-close inspection of a new Model Y’s internals Green stated that “retrofit for intel cars definitely looks impossible - totally different power and other harness and thickness of the unit.”
The news hasn’t been confirmed nor denied by Tesla or its CEO, Elon Musk, but if proven to be accurate it would most certainly disappoint a great number of MCU2 vehicles owners, who were expecting to be offered the possibility of an upgrade, in the same way current MCU1 owners are able to upgrade their chips for a $2,000 (plus tax) fee.
MCU (Media Control Unit) is the computer controlling Tesla’s touchscreen, processors, RAM (short term memory), non-volatile memory (long-term memory), the audio subsystem, 5 amplifiers, WiFi, Cellular, Bluetooth, GPS, the Ethernet bridge, multiple CAN bus communications, the LIN bus, USB ports and many more.
It handles every software operation, excluding Full Self-Driving/Autopilot, which are unaffected by which MCU version a Tesla is equipped with. All Tesla’s built after November 2016 are capable of Full Self-Driving.
MCU2 came out in the spring of 2018 (fall of 2017 for Model 3) as an upgrade to the NVIDIA’s Tegra 3 processor found in MCU1. All cars delivered after that point benefited from the improved responsiveness and extra features that came with the Intel’s Atom E8000 Series CPU.
From a technical standpoint, the two chips possessed entirely different architectures. The release of software update V10 highlighted the differences, as MCU1 owners were excluded from both Tesla Theater and Tesla Arcade. Effectively, MCU1 doesn’t support Netflix, Hulu, YouTube, or any other streaming services that may be added in the future. It also doesn’t support any of the games Tesla added. Additionally, the web browser on MCU2 is much quicker and more capable as it’s built on Google’s Chromium platform.
In summer of 2021 Tesla released the redesigned Model S with a more powerful infotainment processor MCU. At the time no one was sure whether this was Tesla's next generation MCU or whether it would trickle down to other models.
Then in late 2021 the first news of a new Tesla MCU chip generation started to flood the web, with reports coming from China of a new AMD Ryzen-based computer being present in newly delivered Model Y’s.
The new MCU is faster and brings noticeable improvements in responsiveness in the web browser, as well as while using video streaming services, such as Netflix and YouTube.

We’ve known for a while now that Tesla has been using a custom build of FSD to allow its newly produced vehicles at Giga Texas and Fremont to autonomously navigate themselves from the production line to the outbound delivery lot.
While we knew they were using a custom build of what was likely FSD Unsupervised, thanks to a recent post from Tesla AI on X, this has now been confirmed. Tesla has also confirmed it has accrued over 50,000 driverless miles, totalled from vehicles autonomously driving themselves to delivery lots.

For most of Tesla’s vehicles - that’s a 1.4-mile trip that is shared with pedestrians, cars, trucks, and construction equipment. You can see in the video that the Teslas are navigating public roadways and encountering real human drivers.
That’s great news, especially since many were wondering whether Tesla would secure the necessary approvals in time to launch their Robotaxi network in June.
Increased Confidence
Following Tesla’s post to X, Musk followed up by saying that when Tesla launches FSD Unsupervised soon, it will be the first time there will be a generalized, pure AI solution to autonomy. Tesla and several executives continue to post more content about autonomy and the Robotaxi network, leading us to believe they’re feeling confident in the June launch.

Back when Tesla initially announced the autonomous travel of its vehicles from production to loading lots, they mentioned that the Cybertruck was the only vehicle at Giga Texas not receiving that same treatment.
Now, that’s changed - Cybertruck is now also navigating through the Cybertunnel to make its way from the factory directly to the loading docks, all on Unsupervised FSD. And that’s making us even more excited, especially because Tesla was supposed to launch an FSD Update for the Cybertruck a little while ago - but it hasn’t made it to production yet. This update is set to bring Start FSD from Park, as well as Actually Smart Summon - bringing the Cybertruck to feature parity with Tesla’s other AI4 vehicles.

Now that Tesla is confidently using a build of Unsupervised FSD to navigate the tight confines of the tunnel and park, we’re pretty sure that Tesla will likely launch the expected FSD update in the near future.
FSD Update Soon?
It’s been a while since any FSD hardware variant has received an FSD update. It appears that Tesla has been focused on Unsupervised FSD and launching FSD outside of North America.
It seems like we may get a new FSD update soon, and we don’t believe it’ll be just for the Cybertruck. Those who have the opportunity to sign up for Tesla’s new Early Access program will likely be some of the first recipients to receive the FSD update, so stay tuned.
Lars Moravvy, Tesla's Vice President of Vehicle Engineering, recently took to X to pose a question to the community: “Let's make Teslas better… what do you all want for 2026?”
The question absolutely took off, and there were tons of fantastic suggestions about what Tesla owners would love to see from their vehicles in the future.
There were more than 12k suggestions, so let's take a look at some of the most popular feature requests.
Top Suggestions
CyberSUV - A classically styled SUV with a stainless steel exterior.
Faster Charging & Better Charge Curves - Tesla vehicles start off with fast charging speeds, but usually taper off quickly in comparison to other brands. This is especially true when compared to some Chinese brands, which sustain 500 kW charging at up to 70% state of charge. Let's get improved charging speeds on Teslas as well, especially with the 500 kW Superchargers coming in Q3.
450mi / 500mi range vehicles - Lots of customers want longer range vehicles, even though Tesla's analysis says the 300-mile range is ideal for 90% of its customer base. Range really does matter - especially for customers in more rural locations or those who choose to tow or haul with their vehicles.
Ambient Lighting Reacts to Music - This one is pretty straightforward, and it's surprising we don't already have this feature. Having basic integration with the currently playing audio is a neat feature, and really helps to make the entire experience even more seamless and premium.
Refresh Model 3 Signal Stalk Retrofit - Some people really love their signal stalks. While there aren't retrofits available just yet, we do recommend the Enhauto Stalks. For those who want an official retrofit, there is now some hope - Lars responded and said he'll try.
Lumbar Support in the Profile - Right now, lumbar support is the only seat item not saved to the Tesla Profile. This may change soon, as Lars followed up and mentioned that there are a few technical issues preventing it, but Tesla could make it work with some of their magic.
Model 3 Track Pack - The Model S has an exclusive Track Pack as a post-factory retrofit offered by Tesla, including premium brakes, tires, and wheels. The Refreshed Model 3 Performance is a killer track vehicle - but getting real track support from Tesla would be a game-changer for those who love to race.
Some of Our Favorites
Sentry Mode Improvements - Several users suggested adding B-pillar recording to Sentry Mode. And it looks like Tesla has already been working on this, and it'll be available in the upcoming 2025 Spring Update, which will be update 2025.14. Unfortunately, it'll be limited to what appears to be HW4 vehicles due to the additional processing.
Massaging Seats - A touch of luxury for Tesla's most premium models would be nice. Many other luxury brands already offer massaging seats so it’d help keep the Model S on par with these brands. Edit: Corrected that the Model S has never come with massaging seats.
Powershare for More Vehicles - Powershare is a fantastic feature, and bringing it to every Tesla is a must, especially as many other brands, including Ford, Kia, and Hyundai, offer either Vehicle to Load or Vehicle to Home capabilities as an option on their EVs. Tesla recently introduced the Mobile Connector with Powershare capabilities and an Outlet Adapter, but it's still exclusive to the Cybertruck for now.
Starlink Integration - Tesla currently uses cell networks for connectivity, which can sometimes be spotty. Starlink is a clear, high-tech solution that could provide data to vehicles when they have a clear line of sight to the sky.
Grok in Vehicles - Musk has already confirmed that Tesla will be integrating Grok into Tesla vehicles. We expected it to be included in Tesla's Spring Update, but it looks like they'll need a little bit longer. One of the lead xAI/Grok developers mentioned the request with a wink emoji, so it's clear it’s a feature that Tesla and xAI are actively working on. The way users will be able to naturally talk to AI will be game-changing for many users who are used to driving alone.
There was a lot of positivity in the comments, as well as a ton of interesting requests that could eventually be implemented in Tesla vehicles. Lars also responded to quite a few of the comments, which was nice to see.
While nothing is certain, some of these popular requests may come in a future update, while others may need hardware changes if Tesla wants to implement them.
2026 may seem far away, but there's already plenty of coming this year with a cheaper vehicle and the launch of the Robotaxi network.
