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

By Nuno Cristovao

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.

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.

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.

Tesla Plans CyberCanopy Supercharger with RGB Lighting and UFO-Inspired Design

Back in 2023, Tesla put together a rather unique Supercharger site idea - one with a CyberCanopy. This canopy is intended to provide solar power for Supercharging, helping to reduce the impact on the local grid while also providing a futuristic and Cybertruck-themed location that would set it apart.

Unfortunately, the plans never moved beyond the filing stage. Instead, Tesla opened a standard-looking Supercharger at the same Canton, Massachusetts location. However, the site is still well-situated just off the highway and benefits from natural tree cover in the parking area.

However, Tesla is at it again with a concept for another CyberCanopy with RGB lighting. Thanks to MarkoRP for spotting this. No April Fool’s this time.

We want to build a few Superchargers cool enough to be worthy of the trip itself. - Max de Zegher

CyberCanopy 2

This second Supercharger with CyberCanopy is set for Roswell, New Mexico, at the Whataburger in town. Featuring just eight stalls, this will be one of Tesla’s smaller Supercharger sites, but for what it lacks in size, it makes up for it in uniqueness. The charging stalls are covered from the rain by a futuristic, Cybertruck-themed canopy, which will have solar panels installed on the top of it.

According to the plans, the CyberCanopy boasts 20.88kW of solar panels on its roof, providing shelter from the elements while also providing some power back to the grid.

RGB Lighting

At nighttime, the Supercharger will make a big statement. Tesla intends to light the long edges of the canopy, which will not only look amazing, but it’ll actually make finding the Supercharger easier in a large parking lot.

The lighting coming off the edge of the canopy reminds us a lot of the lightbar on the Cybertruck and now the new Model Y. It’s definitely the direction Tesla is moving for all their models, so expect all future models to have it, including the new Roadster and the next-gen model.

Tesla’s Max de Zegher also took to X after the plans for the new Supercharger were found and shared the image above. He stated that Tesla wants to build a few cool Superchargers that will be worth stopping at, even if they’re out of the way a little bit. So it seems like this isn’t just a concept, but an idea that Tesla wants to expand to several areas around the country or world.

Sending Energy to the Grid

This particular site doesn't have a Megapack or other form of energy storage, unlike the upcoming Harris Ranch Supercharger site in California. That means that Tesla won’t be storing the solar energy gained from this site, but instead will be either offsetting the immediate grid impact or serving energy back to the grid when the site isn’t actively charging.

Tesla will likely be incorporating V4 Superchargers, including both V4 posts and the new, more powerful V4 Cabinets, as the permit states that Tesla will be redesigning the site internally before beginning construction. For Cybertruck owners, 500kW charging may be around the corner.

We’re hoping Tesla continues to deploy these kinds of Supercharger sites around the world - they make a stylistic statement about Tesla’s futurism, like the Shell gas station that was upcycled into a Supercharger site earlier this year in Spain.

They also make a big impact for ownership because it is a far more comfortable charging experience when you stop at a site that’s shaded from the elements - and one that’s better for the environment with offset emissions.

Imagining Tesla’s Robotaxi Network Charging Stations

By Karan Singh

It was a rainy April 1st when a news-searching author went on a delve into the depths of April Fools to find fact from falsehood. And while we found a lot of fantastic jokes, we also found some good ideas.

So, with a shoutout to MarcoRP on X, whose April Fool’s Joke gave us a good run for our money for a couple of minutes, we thought to ourselves - what would a Cybercab Charging Station / Cleaning Hub really look like?

Cybercab Wireless Charging Sites

Now, before continuing, we’d like to point out that the image up top is a joke from Marco - it isn’t an accurate or real site map submission from Tesla. However, it gave us the impetus to think critically about what is required for a Robotaxi fleet, based primarily on the Cybercab, to be able to service a city.

Requirements

Tesla will likely need to charge a small fleet of Cybercabs at a single time and in a single place. That means that the site needs to be large enough to cover a major metro area while also still being compact enough to not cost too much money to build out.

In addition, we need to factor in charge times. The Cybercab is likely to launch with a battery around 50 kWh, which will result in a range of approximately 300 miles. With that much range, the average Cybercab may not need to charge more than once or at all during daytime shifts, so instead, most of the vehicles will charge overnight.

MarcoRP

Math and Charge Times

The overnight charging means that most of these vehicles could be charged slowly. When we did some back-of-the-napkin math last year, we determined that Tesla’s wireless charger will likely peak around 17 kW (for comparison, Tesla’s Wall Connector at 32 amps charges at about 7 kW). If we scale Tesla’s wireless charger down slightly to 10 kW, accounting for some energy loss and the potential size of the site, that means a Cybercab will be able to charge in about 5 hours.

Tesla’s upcoming V4 Supercharger unit can currently handle 1.5MW per cabinet, but this slower-speed charging is A/C, not DC, which means there is a step-down loss of about 3-5%. Let’s make that a comfortable 10% for any other overages, but we can estimate around 1.35MW of power. That 1.3MW will easily handle charging up to 100 Cybercabs at once - all wirelessly, using Tesla’s unique beam-forming and beam-steering technology to keep efficiency high at every single stall.

Within about 5 hours, a whole fleet of 100 Cybercabs could be charged overnight when electricity rates are cheaper and still be out in time for the morning commute.

While this is all just hypothetical, it really does make sense that Tesla will be establishing these sites that won’t require much space or a ton of energy.

Tesla recently curtained off a large section of the parking garage at Giga Texas, as well as some of their chargers on the eastern end of the facility, leading us to believe they may just be testing this at scale internally.

There’s a lot to look forward to with Tesla’s V4 Supercharger deployment coming this year and with Robotaxi launching in just a couple of months.
