Cybertruck

Front Display: The Cybertruck's display is 18.5-inch, horizontal screen, making it the largest display in any Tesla. The display has a resolution of 2650x1440, which is about a 16:9 screen ratio, similar to the Model Y.

Instrument Cluster: Like the Model 3 and Model Y, the Cybertruck does not include an instrument cluster, instead the speedometer, battery information and visualizations are displayed in the center display.

Rear Display: The Cybertruck has a rear display between the two front seats like the Model S/X. The touchscreen display measures 9.4" diagonally and has a resolution of 1440x900. Although this rear screen is used mostly for entertainment, it comes with a 16:10 aspect ratio instead of the more traditional 16:9.

Front Display: On the other hand, the Model 3 and Model Y take a different approach to screen design. Both models lack an instrument cluster, opting instead for a single, central 15.4-inch touchscreen with a 16:9 screen ratio. The display features a resolution of 1920 by 1200, which comes in just below 150 PPI. This minimalist approach further emphasizes Tesla's commitment to a clutter-free, user-friendly interface.

Instrument Display: Like most Teslas, the Model 3 and Model Y do not include an instrument cluster.

Rear Display: Like the newer Model S & X, the new Model 3 (late 2023+) also features a rear display. The touchscreen display measures 8" diagonally, but is only available in the newer Model 3. It's also expected to arrive in the refreshed Model Y when it arrives in 2025.

Model S & Model X - Screen Size & Resolution

2012-2020

Between 2012 and 2020, the Model S and Model X were equipped with vertical screens, which stood out due to their impressive size and orientation. These screens measured 17 inches diagonally and allowed intuitive control of the vehicles' various features.

In addition to the central touchscreen, both models featured an instrument cluster screen behind the steering wheel, displaying vital information such as speed, range, visualizations and charging status. The instrument cluster features a 12.3" screen with an 8:3 aspect ratio and a resolution of 1280 by 480.

2021-Present

In 2021, Tesla introduced a significant update to the Model S and Model X, replacing the vertical screens with horizontal ones. The new 17-inch screen boasts a 16:9.5 aspect ratio, providing users with an even more immersive experience. The display has a resolution of 2200 by 1300 pixels which is about 150 pixels per inch (PPI). Tesla later introduced the ability for the center display to tilt left and right so that it could face the driver or passenger.

The instrument cluster remains present in the newer models, ensuring drivers have easy access to crucial information, but Tesla added an 8" rear display for entertainment. In 2022, Tesla updated the rear display by reducing its bezels, resulting in a slightly larger screen size. The rear display has a resolution of 1440x900 with a 16:10 aspect ratio.

Finally, the Tesla Semi, a big electric rig designed for long-haul transportation, features dual 15-inch screens located to the left and right of the driver. These screens replace the traditional instrument cluster, providing the driver vital information and access to various controls. However, there is no rear screen in the Semi, as it's not necessary for its intended use.

Tesla's commitment to innovation and user experience is exemplified by integrating large, intuitive touchscreens in their vehicles. From the early vertical screens in the Model S and Model X to the current horizontal screens and the upcoming Cybertruck, Tesla continues to push the boundaries of automotive design and technology, ensuring that their vehicles remain at the forefront of the electric vehicle revolution.

Tesla’s Robotaxis Have a Strange New Rear Bar — Here’s What We Know

@DirtyTesLa on X

We’ve already seen that Tesla’s Project Halo has some hardware modifications not found on consumer cars. While some of these upgrades, like the second communications unit, have a clear purpose, another change is a bit more confounding.

Early-access testers in Austin spotted a simple, flat, likely metal bar under the rear trunk of the Robotaxi Model Ys. While we’re still not sure what exactly this new bar is for, we do have some speculative ideas.

The community has also floated some fantastic theories, but Tesla clearly put it here, and on these Robotaxi vehicles, for a specific purpose. Grab your notepads, we’re about to do some theorycrafting.

Could Be Wireless Charging

By and far, the most plausible and exciting theory is that this bar is related to future wireless charging capabilities and testing.

For a Robotaxi network to scale efficiently, the entire process, from cleaning to charging, must be autonomous. Relying on a human to plug in each vehicle, or even a complex robot arm, introduces a logistical bottleneck and a potential point of failure.

The logical endpoint here is that wireless inductive charging is a game-changer. A vehicle simply parks over a designated pad at the depot to begin charging, without any interaction.

The metal bar is in the exact spot where Tesla could potentially mount testing gear, or even the vehicle-side receiver for more informal testing, without needing to commit to a wholly new underbody design.

Tesla previously acquired Wiferion, a German inductive charging technology company, and demoed the wireless charging solution at We, Robot. With a series of patents on beam steering and wireless charging circuits, Tesla has been hard at work building up their tech base to support wireless charging for Robotaxi.

What It Probably Isn’t

We’ve seen several other theories discussed, but they really begin to fall apart under closer scrutiny. 

The first is additional underbody protection. While it is potentially practical, the bar’s position is far too rearward to offer any additional protection to the high-voltage battery pack or the rear drive units. Additionally, Tesla prefers to integrate this type of protection directly into the vehicle’s Gigacasting. Tesla has already made significant improvements to the structural rigidity of the new Model Y’s Rear Casting, so this makes no sense.

Next up is a potential camera spray shield for the rearview camera. The centralized placement of the bar means it doesn’t actually protect from the rear wheels pushing road spray out and upwards. It simply won’t have an impact on the rear camera that we can see. 

Rounding up the theory crafting is a new aerodynamic part. However, the bar is flat and seems more like a mounting point than anything aero-related, such as the new rear diffusers spotted on the Model Y Performance. The bar likely makes more drag than it reduces.

Small Part, Lots of Ideas

When considering the logistical requirements of a large-scale autonomous vehicle fleet, wireless charging is a natural choice, especially given the mounting point. This simple metal bar is likely a preparatory step for Tesla to mount engineering samples for wireless charging in the near future.

If you’ve got any other ideas on what this could be, we’d love to hear what you think on social media.

Tesla’s ‘Project Halo’ Revealed: The Upgraded Model Ys Behind the Robotaxi Network

@DirtyTesLa on X

While the performance of FSD has been the star of the Robotaxi Network, new details are emerging about Tesla using modified Model Ys for the service. According to a report from Business Insider, the program to modify some vehicles for Robotaxi is known internally as “Project Halo”, and it involves more than just a newer FSD version.

These details help connect the dots between the subtle physical changes that have been spotted on the Robotaxi Model Ys.

Physical Clue: Expanded Rear Housing

Eagle-eyed observers in Austin were quick to spot a key physical difference on the Robotaxi fleet vehicles: a larger-than-normal housing on the rear window. This immediately sparked speculation that Tesla had integrated new components to support the Robotaxi rollout. We initially expected that these may have been minor changes like Tesla is known to roll out, but now we have a better idea of what exactly is under that new housing.

Halo Communications Unit

According to the insider source, Tesla’s Halo vehicles are equipped with a second telecommunications unit. That’s a significant change from customer vehicles, which are equipped with just a single unit near the roof of the vehicle.

According to the report, this unit serves a dual purpose. It provides redundant, high-precision GPS data, and most importantly, allows the vehicle to maintain a constant, reliable connection with Tesla’s Robotaxi support team. That includes connectivity for teleoperation, if necessary. This hardware may be the physical backbone for the human assistance portion of the pilot phases of Robotaxi.

As we saw in the command center image shared by Ashok Elluswamy, these vehicles are streaming video from six cameras, potentially putting too much of a strain on the vehicle’s single cellular modem.

Not a Tesla App

Probably Not Starlink

While we initially mused that this could be holding a Starlink Mini dish, the space taken up by the housing is far too small to permit the installation of a Mini. Instead, it is approximately the same size as the telematics control unit that Tesla installs in the ceiling of its newer vehicles, which include a 5G modem.

Tesla is likely using the second connection for redundancy or to increase data throughput.

Quickly Iterating on FSD

All that data throughput likely serves a third purpose as well - providing live data streaming for Tesla’s Robotaxi Operations Hub back at Gigafactory Texas. That isn’t necessarily for support teleoperations, as we previously mentioned.

It is likely that Tesla is pulling video data from the Robotaxis to quickly improve the current version of Unsupervised FSD. Early-access testers noticed that in just a day, Tesla was issuing improvements, which means data is moving from vehicle to training in a snap.

Yesterday robotaxi would get like an inch away from this wall (first video) while pulling up. I saw 4 different Robotaxis do it.

Today it seems fixed. I've seen 2 robotaxis. Is Tesla really changing things this quickly? pic.twitter.com/zfdchBL771

But Elon Said!

Well before the launch, Elon said that the vehicles used for Robotaxi would be unmodified vehicles coming straight from the factory. It seems that isn’t exactly true, but it could be in the future.

So, how can we reconcile the unmodified statement with the clear evidence of Project Halo hardware? The key here lies in the difference between a stock Tesla’s FSD capabilities, versus the operational hardware required to run a commercial Robotaxi service.

Elon’s entire point is that the fundamental FSD hardware — the cameras, sensors, and FSD computer — is standard on every car coming off the line. From a capability standpoint, a consumer car can perform Unsupervised FSD.

The second communications unit is best understood as service hardware. They don’t make the car drive better, but they provide the redundant connectivity needed for operational oversight, remote assistance, and the massive data uploads required for a pilot program.

This hardware may also be necessary for Tesla to meet regulatory compliance requirements for a commercial autonomous vehicle service for the foreseeable future.

These are unmodified Tesla cars coming straight from the factory, meaning that every Tesla coming out of our factories is capable of unsupervised self-driving! https://t.co/n94ln0Uas6

Camera Cleaning

The Business Insider report also mentioned that Halo vehicles would have self-cleaning cameras. That isn’t a new hardware feature; in fact, it appears to refer to the software feature where Robotaxis can thoroughly clean its front-facing cameras [video and details], which will eventually make its way to owner vehicles.

Wrapping Up

The insider confirmation of Project Halo and its specialized hardware helps to provide a clearer picture of exactly what Tesla is doing with Robotaxi. It seems that for now, it’s not simply just consumer cars running advanced hardware, it’s a fleet of very lightly purpose-modified vehicles meant to support the pilot rollout.
