Tesla Model 3 and Model Y to have faster processors, 12v li-ion battery and more

New Tesla Model Y Performance models coming out of China this month have the biggest changes we've seen to the car so far. The cars have several major hardware changes that improve the infotainment system, noise isolated and more.

Tesla starts using 12v lithium-ion batteries

Infotainment Processor

The first major upgrade is the processor that powers the car's infotainment display. It has been upgraded from the Intel Atom processor to a much faster AMD Ryzen chip. It's the same chip that's used in the redesigned Model S and X, although the Model S and X feature 16GB of ram while these new Model Ys appear to have only 8GB.

This processor is much faster than the Atom processors that are currently in Model 3s and Model Ys.

Graphics Processor

The new Model S and X feature a dedicated GPU that is capable of PS5-like graphics. The system is able to play one of the most intensive video games, Cyberpunk 2077.

We thought that this chip would be exclusive to Tesla's higher-priced vehicles, but surprisingly, the new Model Ys feature the same graphics processor in the new Model S and X.

It appears that Tesla plans to keep the infotainment and graphic processors the same across their entire lineup of cars. Having such an advanced processor will surely open up the possibilities to new games and enhanced capabilities in the car.

MCU 3

When the Model S was unveiled, it contained this new processor and high-end gaming capabilities. At the time, no one was sure whether this hardware would be exclusive to the Model S or whether it would trickle down to other vehicles.

Does AMD Ryzen seem to make the new MIC Model Y Performance look smoother than ever?

What do you think?

AMD YES？

However, at this point it's fairly certain that the AMD Ryzen chip and graphics processor Tesla is using will be a part of Tesla's MCU 3 and will be used across their entire fleet.

Software

Although the new Model Ys coming out of China contain the same CPU and GPU processors as the new Model S, they still feature the same 15" screen as other Model Ys. They also still use the same user-interface as all current Model Ys, although they're certainly capable of running the same Tesla interface in the new Model S.

It's not clear whether the new interface is still being adapted for slightly smaller screens, but we expect that these new Model Ys with MCU 3 will be running the updated Tesla interface in the future.

We don't know if vehicles with MCU 2 will be able to run the updated interface at some point. Tesla employees have previously said off the record that MCU 2 isn't capable of running the new interface found on the new Model S, but it's possible that Tesla figured out a way to run the new interface on MCU 2 vehicles. If the new interface comes to MCU 2 cars, it'll likely need to be adapted to be able to run on slower hardware or limit some of its features, such as dragging and docking windows.

12v Battery

All Teslas up until the release of the redesigned Model S and Model X used 12v lead-acid batteries. This lower voltage battery is used to power door locks, electronics and other smaller items in the car that can't be run off of the high voltage battery.

The 12v lead-acid batteries in Model 3 and Model Ys are the same kind found in just about every other car. The battery is recharged off of the car's main battery. These lead-acid batteries last about four to five years, but we've seen them last only a couple years as well.

With the new Model S, Tesla switched to a lithium-ion based battery that is much lighter and lasts much longer than lead-acid batteries.

These new Model Ys coming out of GIGA Shanghai are coming with the same lithium-ion battery that is found in new Model S and X vehicles.

The battery is estimated to last the life of the vehicle and never needs replacing. This is a nice improvement and it's a great way for Tesla to reduce Tesla service visits.

It also helps increase customer satisfaction and lower the maintenance required for Teslas even further.

Although replacing a lead-acid battery in a vehicle isn't an expensive procedure, having a lithium-ion battery that doesn't need to be replaced is a nice improvement for all future Tesla owners.

It'll be interesting to see whether Tesla will be able to upgrade lead-acid batteries to their lithium-ion models in future service calls for any customers that need one replaced.

Other Changes

Another change that has been noticed in these new models is that the rear passengers windows now have double laminated glass similar to the front windows, to help further isolate road noise.

It's possible that there are other smaller changes in these new models as well, but these have been the major changes observed so far.

These hardware changes are currently exclusive to new Model Y Performance models coming out of China. Tesla slowly makes changes to its lineup throughout the year when possible, but the changes we're seeing here are major improvements to the vehicle.

You can be sure that all Tesla factories will adopt the same hardware changes we're seeing in China across all models in the coming weeks or months.

There has now been a video posted that compares how much faster MCU 3 is compared to MCU 2 when loading various apps.

Exclusive: Tesla’s AI Assistant Now Uses Vehicle Data for Personalized Responses

Not a Tesla App

As part of Tesla’s App Update 4.42.5, which is now available on both the Android and iOS App Stores, Tesla has rolled out an improved AI Assistant.

If you’re not familiar with Tesla Assist, it’s the company’s AI-powered assistant, which can be found in the Service section of the Tesla app. The assistant was first introduced with app update 4.35.5, and it has slowly improved to help answer the most common Tesla-related questions.

At first, Tesla Assist could answer general support questions like “What is Sentry Mode?” or “Why is my range lower than expected?” It acted as a helpful starting point for answering questions, but the responses weren’t personalized for you or your vehicle. However, with this latest update, that is changing.

Personalized Support

The latest version of Tesla Assist introduces personalized responses. You can specify which vehicle or product your question relates to and ask specific questions about your vehicle. For now, the responses are limited to a few categories, like tire pressure, however, we expect the assistant to have access to more vehicle information in the future.

For now, you can ask questions such as, “What alerts were recently triggered on my vehicle?” or “Is my tire pressure low?”. We’ve also been successful in asking whether a particular accessory, such as a key fob, would work with our vehicle.

Tesla provides these answers based on information in their owner’s manuals, tutorials, and your vehicle’s details and data.

Just like before, Tesla continues to provide links to related articles, such as the Owner’s Manual or the Service Manual, depending on the context.

Not a Tesla App

Future Releases

While the assistant can’t access every detail just yet — how many miles are on my vehicle — it’s already capable of pulling a lot of service-related information. It appears Tesla may be looking to expand this to other areas, with some responses stating, “Based on your vehicle’s data…”

It’s not clear what’s powering this assistant, but it could be some version of Grok, which will soon be available inside of Tesla vehicles.

The AI-based assistant can be found in the Service section of the Tesla app or by going into the main menu and tapping the question mark in the upper-right corner. Let us know if you’ve seen any other interesting responses from Tesla Assist.

Tesla to Build Third Megafactory in Texas With $200M Investment

Not a Tesla App

Tesla has revealed the location of its third Megafactory, following Mega Lathrop and Mega Shanghai. The new facility will be in Brookshire, Texas, covering 1.6 million square feet—twice the combined size of Mega Lathrop and Mega Shanghai.

Tesla has had a lease deal at the Empire West industrial park since at least late 2021, where a third-party company has been managing the shipment of vehicle parts from Giga Texas and Fremont factories service centers across North America.

Mega… Factory?

The name says it all. Tesla’s Gigafactories focus on vehicle production—like Giga Texas, Giga Berlin, and Giga Shanghai—while Megafactories are dedicated to Tesla’s energy products.

Tesla Energy is expanding rapidly, with executives suggesting it could soon become one of the company’s largest revenue streams as demand continues to outpace supply.

Mega Brookshire will manufacture Megapacks and Powerwalls, Tesla’s primary stationary energy products. Both use LFP batteries, meaning their production won’t impact Tesla’s vehicle output, as most of the company’s cars rely on NMC batteries.

Looking at the Numbers

Tesla plans to invest approximately $194 million in upgrades and equipment across the two buildings, with the facility projected to generate between $8 billion and $10 billion in annual revenue.

Of that investment, $44 million will go toward facility improvements, such as parking, electrical upgrades, accessibility, and structural updates. The remaining $150 million will be allocated to Tesla-sourced manufacturing equipment for product production.

Tesla will also be employing approximately 1,500 people in the local community, which will be a considerable economic boost for the local residents.

Mega Brookshire Phase 2

The Megafactory plans also include funding for a distribution facility, with Tesla set to invest $31 million in its purchase and an additional $2 million for equipment and facility upgrades. Given its proximity to Giga Texas, it’s likely that Mega Brookshire’s distribution terminal will support the Tesla Semi.

This marks Tesla’s first factory announcement since Mega Shanghai. While there were initial plans for Giga Mexico, where Tesla initially planned to build their next-gen vehicle, those plans have seemingly been shelved as Giga Texas and Fremont continue to expand.

Although an official timeline for Mega Brookshire’s launch hasn’t been shared, Mega Shanghai is set to begin production soon after breaking ground in May 2024. Based on that timeline, Mega Brookshire could be operational by mid-to-late 2026.
