Tesla FSD Hardware 4.0 Revealed: More Cameras, New Placements

Tesla's FSD hardware 4.0 is uncovered

@GreenTheOnly/Twitter

News and rumors have been heating up about Tesla's upcoming FSD hardware 4.0. Now, thanks to @GreenTheOnly, we have our first look at Tesla's latest FSD hardware, version 4.0.

The new hardware will not only include a faster computer and higher resolution cameras but it will include HD radar, additional cameras and new camera placements.

Cameras

It's been rumored for a while now that Tesla will use upgraded camera sensors with increased resolution. We reported last year that these new cameras are also expected to have LED flicker mitigration that will aid in reading digital signs. 

Tesla's current cameras produce 1.2 megapixels, and while we don't know for a fact what the updated resolution will be, numerous rumors have pointed at them having 5 megapixel sensors.

One of our sources says that while the increased resolution will be useful in certain scenarios, it won't be 'critical' because the higher resolution also comes with some downsides, such as more noise and will require additional processing power.

However, we expect that it will be useful in certain scenarios and Tesla may even be selective about when the increased resolution is used. The new cameras will also provide a better picture and will benefit non-FSD features such as Sentry Mode.

However, the increased resolution of the new cameras is only a small part of the upcoming camera changes.

Camera Placement

Tesla's hardware 4.0 features 12 camera connectors

Tesla's hardware 4.0 has 12 camera connectors on board, with one being labeled spare. All current Teslas feature nine cameras in total. Three of them are forward-facing cameras and located underneath the windshield, two are on the fenders, two on the B-pillars, one in the rear and one for the cabin camera.

A leak last month revealed that Tesla plans to reduce the number of front-facing cameras to two, down from three. This is likely due to the higher-resolution cameras, making the third telephoto lens unnecessary.

That means there may be up to three additional cameras in hardware 4.0, or possibly four if you count the spare. According to Green, these three cameras appear to be destined for the vehicle's front bumper, although it's not clear in which direction they'll be aimed.

There have been various documented issues where Tesla has a blindspot when the vehicle is coming out of a secondary road that is obstructed by buildings or other objects. Having a camera that could look to the sides near the front of the vehicle would solve these situations, by giving it better than human vision since they'd be placed near the front of the vehicle.

According to the camera port names, it appears that Tesla may also be repositioning some of its cameras. The B-pillar cameras, which look forward, may be moved onto the vehicle's fenders to presumably help provide a better view as well.

Another leak last month revealed that Tesla is added a heater element to cameras in the B-pillar of the vehicle, which will help with fog build-up underneath the glass. 

Processing Power

Hardware 4.0 was previously rumored to be about 2-4x faster than hardware 3.0. Some of this power will undoubtedly go toward processing the new camera feeds and additional pixels the new cameras are providing. However, the additional power is crucial given that hardware 3.0 is nearing its processing limit.

Green provided the specs from the new hardware's chips, revealing it contains 20 cores, up from 12, and it maxes out at 2.35 GHz. Green also talked about the number of TRIP cores increasing from two to three and maxing out at 2.2 GHz.

While the number of cores and its frequency don't reveal how powerful this new hardware may be, Green says that the new hardware has 'a lot less improvement than many hoped for.'

It's not clear how much faster hardware 4.0 will be compared to hardware 3, but it sounds like the improvement may be toward the lower limit of the 2-4x speed bump we were expecting.

The hardware specs provided are per node, with the board having two nodes, which are expected to be used for redundancy.

Redundancy

When Tesla introduced hardware 3.0, they also built it for redundancy in case of emergencies. Each board was built with two identical nodes. Both nodes could compute the same data and compare the outputs, letting the vehicle know if there was an issue. If one node failed, the vehicle could also continue driving itself long enough to pull over safely.

However, as Tesla's processing requirements increased, redundancy was removed on hardware 3.0 so that Tesla could leverage the processing power of both nodes.

With hardware 4.0, Tesla has once again added redundancy into their hardware, not only in terms of chips and processing but power redundancy as well.

Retrofits

During Tesla's earnings call last month, Elon talked a little bit about hardware 4.0, saying that it would not be economically feasible to perform retrofits.

However, given this look at Tesla's latest FSD hardware, it all but confirms that Tesla has no plans to offer any sort of retrofit.

Hardware 4.0 is also much more than just a faster computer. The power draw is much higher on hardware 4.0 than on hardware 3. The form factor is also completely different and will not fit in a previous model without modifications.

Tesla's previous FSD hardware upgrades were either camera upgrades or a computer upgrade, both of which were easily swappable. However, the hardware 4.0 suite now includes additional cameras, new camera placements, a new computer form factor, and an HD radar, making a retrofit unrealistic in every way.

There may be hobbyists that will dedicate their time and money to retrofitting their vehicles, but that's as far as we expect retrofits to go. The time and money Tesla would spend on retrofitting a vehicle would not make 'economical sense.'

Radar

Tesla's hardware 4.0 package augments vision with an HD radar.

Tesla started removing radar from their vehicles in 2021 with the Model 3 and Model Y. They later removed radar from their Model S and Model X vehicles as well in favor of a vision-only system.

However, with hardware 4.0, Tesla is reintroduced radar with a high-definition radar named Phoenix. HD radar is a step up from traditional radar, letting Tesla more accurately create an image with radar alone.

The inclusion of an HD radar isn't a surprise, as Elon Musk has previously said vision with high-res radar would be better than pure vision.

With hardware 4.0 Tesla is also going the extra distance with protecting its sensors. Not only will some of the cameras contain heaters to prevent weather-related issues, but Tesla will include a heater for the radar as well.

The radar heater will prevent snow and ice from accumulating on the front of the vehicle and blocking the radar signals.

Power Consumption

Since hardware 4's chips are more powerful it isn't a big surprise that they also require additional power. 

According to Green, hardware 3 consumed about 100 watts max, which is about the same as hardware 2.5. Hardware 3 was created with the same power restrictions as hardware 2.5 since it needed to be easily retrofitted.

However, since hardware 4.0 isn't going to be retrofitted, it didn't come with the same design restrictions. We don't know what hardware 4's max processing power is based on the information disclosed, but it will apparently idle at 80 watts, which is about double the idle power of hardware 3.

Which Models Will Have Hardware 4.0

Green believes that Tesla is producing Model S and Model X vehicles with hardware 4.0 now. However, Tesla is hanging on to them and they're not being delivered yet.

Tesla has their upcoming March 1st event titled Investor Day, where they may reveal hardware 4.0 to everyone. Possibly with a surprise announcement that all current vehicles contain hardware 4.0.

It's not clear whether the Model 3 and Model Y are currently being manufactured with the new hardware, the Model 3 and Y lines in China are currently paused for retooling which could be related to hardware 4.

First Look at Tesla's V12 User Interface, Full Screen Visualizations and New Media Player [Updated: Photos and Video]

Tesla's latest V12 user interface will change the look and feel of some of the vehicle’s operations. This new interface, announced on X, is already partially available on the Cybertruck but will now be rolled out to the Model 3 and Model Y, equipped with AMD Ryzen processors according to Tesla. However, the new Model S and Model X will likely receive it as well, although possibly not at the same time. It integrates several new features and aesthetics that set new standards in vehicle interface design.

The new interface will become available in Tesla update 2024.14, which started rolling out to employees yesterday.

New Parked Vehicle Visualization

A standout feature of the v12 UI update, not to be confused with FSD v12, is the centralized vehicle visualization, which dominates the display while parked (video below). This design choice enhances visual appeal and improves functionality by placing critical vehicle performance metrics, and status updates front and center. Similar to the layout in the Cybertruck, this feature provides drivers with a clear and immediate view of their vehicle's status and shows off the gorgeous 3D model.

New Media Player

There’s a new media player that’s larger and easier to use. By increasing the size of the media player, Tesla is now able to fit additional options that were hidden before, such as EQ and audio settings, the search icon and shuffle and repeat options.

The new media player appears while the vehicle is parked, driving or while the visualizations are in full-screen mode.

The media player is available on the Model 3 and Model Y and according to Tesla it’ll be limited to vehicles with the Ryzen-based infotainment center.

Improved Navigation

The navigation system will see several improvements. You’ll now see a little trip progress bar that lets you visually see how far along you are on your route.

If your vehicle has a rear screen, as in the new Model 3, the redesigned Model S or Model X, then trip information such as ETA will also be displayed on the rear screen.

Tesla already has the ability to update your route if a faster route becomes available. You can change some of these settings under Controls > Navigate. However, now the vehicle will show you if a faster route becomes available and gives you a chance to cancel the updated route if needed.

Expanded Autopilot Visualizations

Tesla is now bringing its full-screen visualizations outside of North America. However, there will be some improvements as well. In addition to being able to have the visualizations go full screen, there will now be a small map displayed in the corner as well.

That’s one of the issues with the full-screen FSD visualizations right now. If you make them full-screen, you lose your navigation map completely and only have the next turn available.

This will be the first time full-screen visualizations are available outside North America. It’s not clear whether all the FSD visualizations will be available such as traffic lights, curbs and more will be displayed, but Tesla has slowly been adding additional visualizations for non-FSD users, so there’s a chance that this feature will finally display all FSD visualizations to users outside of North America.

It’s not immediately clear whether this feature will require Enhanced Autopilot (EAP) or FSD.

Update: The full-screen visualizations do not require FSD or EAP, but unfortunately the visualizations displayed are still the same ones as in previous updates, so it won’t display the surrounding environment and curbs.

Full-Screen Browser Support

With this update, Tesla will finally let you manually make the browser full-screen. While this will make Tesla’s Theater apps a little redundant since they just loaded the website of the selected streaming service, you’ll now be able to stream any video service full screen, as long as the service supports Tesla’s browser.

As expected, the full-screen button will only be available while the vehicle is parked.

Checking Compatibility

Owners can verify their vehicle’s compatibility with the new full-screen visualizations while parked and driving by navigating to Controls > Software > Additional Vehicle Info on their Tesla’s touchscreen. This update is tailored for Tesla vehicles equipped with the AMD Ryzen processor.

Tesla's Next FSD v12 Update Will Be Available For Users on 2024.8

Tesla will soon roll out a FSD v12 which is compatible with update 2024.8 Tesla began its public rollout of FSD v12 last month, which brings a much more refined, human-like experience to the self-driving software.

To celebrate the achievement and show owners how big of an improvement FSD v12 is, Tesla offered a free month of FSD to all owners with compatible vehicles in the U.S. and Canada.

However, there was a caveat. The latest FSD v12 (v12.3.4) is Tesla update 2024.3.15. Since Tesla doesn't roll back updates since the process isn't rigorously tested, that means many owners who had already received Tesla update 2024.8.9 were left without a free trial and access to FSD v12.

Subscribing to FSD on Update 2024.8

In fact, if you're in the U.S. or Canada and subscribe to FSD while on update 2024.8.x, you'll actually receive the older, and quite a bit worse FSD v11.4.9.

The FSD v12 update has been highly anticipated and aims to finally upgrade Tesla’s ADAS level 2 system to something higher. Musk has talked about level 4 or 5, and even recently said Tesla is going all-in on FSD.

FSD v12 for Update 2024.8 Is Coming

Rohan Patel, who recently left Tesla, recently said that Tesla is already working on an FSD v12 update that is compatible with users on update 2024.8.x. This means that the next FSD update may finally be based on the 2024.8 codebase.

However, just this morning Tesla released the next major update to the platform, update 2024.14 for employee testing. The update is massive and includes an updated UI, hands-free trunk opening, a full-screen browser and more.

However, Patel never specified which codebase the next FSD update would be based on. If it's based on update 2024.8, then users who are upgraded to 2024.14 in the next couple of weeks may face a similar fate as users on 2024.8 today.

Release Date

Patel said to expect the release of the next version of FSD v12 this week. Since update 2024.14 is still being tested with "wave 1" employees, we'll likely see one of two things happen. We may see the next FSD update be based on 2024.8 and released very soon, or it'll be based on update 2024.14, but it may not be available for another couple of weeks.

Once this update arrives, owners with a Tesla on 2024.8.x will finally be able to update and receive their one-month trial of FSD v12 and finally experience what everyone has been excited about.
