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.

With the first Tesla Robotaxi rides starting shortly for early access users in Austin, Tesla has published a detailed set of rules for its first passengers.
They outline everything from who can ride to how you can behave in a car with no driver, and are designed to ensure safety. Tesla is using a safety monitor during the initial rollout phases, so the front passenger seat will not be available for customers.
Who Can Ride
Tesla has laid out clear guidelines on who is eligible to be a passenger, as well as some expected in-car conduct.
You must be at least 18 years old to book a ride and to ride alone. Riders are permitted to bring one guest, provided that the guest is also over the age of 18. You cannot book a ride for another person; the account holder must be present for the entire trip.
That’s all pretty straightforward, and we expect Tesla to relax some of the rules in the coming months. That means that once the safety monitor is gone, the number could increase to three or four.
How to Behave
All passengers must remain seated with their seatbelts fastened for the entire duration of the ride. There is a strict prohibition on smoking, vaping, or consuming alcohol or other drugs inside the vehicle.
Riders are also asked to be courteous and leave the Robotaxi in the same condition as they found it. Those who damage or dirty the vehicle may be charged an additional, currently unspecified fee after the ride.
Hands Off: Driverless Vehicle
This is where the rules get a bit more interesting, focusing on the unique fact that the Model Ys that Tesla is using still have driver controls.
Riders are prohibited from sitting in the front-left driver’s seat. Additionally, riders must not tamper with, modify, or attempt to physically manipulate any vehicle equipment, including the steering wheel and pedals.
Interestingly, Tesla also has a rule on reverse-engineering and intellectual property protection. While photos and videos of the experience are permitted, riders are prohibited from bringing onboard instruments or equipment intended to record, measure, or conduct surveillance on Robotaxi.
Service Animal Exception
For riders with disabilities, Tesla has outlined a specific policy. Only small service animals that are trained to work or perform tasks are permitted in the vehicle. No other pets are allowed.
However, riders are not required to provide proof; however, support may ask you to confirm that the animal is required due to a disability and what task it is trained to perform.
At this point, we’re not sure whether Tesla will allow non-service animals in its Robotaxi Network in the near future. It would make sense if they did - many people travel with their pets, or need to take them from one location to another - but for now, only service animals will be allowed.
Tesla is definitely taking a safety-first approach in the initial launch, and with the presence of the Safety Monitor, they’re being very cautious. There is a long way to go before the average person becomes comfortable with an autonomous vehicle with no one in the driver’s seat, and building public trust is a good first step.
After several sets of spy shots showing camouflaged prototypes, the new Model Y Performance has finally broken cover in the German Alps. The performance variant was finally spotted completely undisguised and driving on public roads.
The video, captured by Nextmove on YouTube, gives us a great look at some differentiating features of the Performance variant.
Performance Model Aerodynamics
The new video confirms that the Model Y Performance model will receive a unique and more aggressive aerodynamics package. Clearly visible in the video is a new rear diffuser on the lower bumper, which is much more pronounced than the one on the standard Model Y.
Also confirmed is the longer, carbon fiber spoiler on the liftgate. Tesla is sticking with the carbon fiber look for its Performance variants, and this one in particular appears to be longer than the one on the original Model Y Performance.
New Badge & Wheels
Carscoops
For the first time, on what is likely a production-intent vehicle, we can make out a blurry shot of what appears to be a performance badge on the right side of the trunk. While the exact details are hard to make out, it appears to be a new icon in orange or red, similar in design to the Model 3 Performance Ludicrous badging.
The vehicle is also sporting the same new Performance wheels that were previously seen on the prototype, making the rounds on the Nürburgring. These unique wheels appear to be exclusive to the Performance variant, and look like they’re the first staggered option for the new Model Y.
Launch Soon
The appearance of a fully uncovered vehicle driving on public roads is typically one of the final stages for Tesla before it launches a new vehicle. We saw this with the lightly refreshed Model S and Model X just recently. While the key visual differentiators are all but confirmed, we’re still waiting on the most important parts: the official 0-60 mph time and details on the updated dynamics. It’s clear Tesla has some engineering magic working behind the scenes, and we can't wait to see the final results.
