Tesla Model Y wiring efficiencies questioned in latest Munro teardown
Sandy Munro took the opportunity to show the Tesla Model Y’s new wiring structure, however, the Detroit automotive veteran noted to be “kind of disappointed” in some of its design.
“What I see here is a nice application of the wire troughs and candy striping…But unfortunately, there’s just as many wires; the wires are just as long,” Munro said.
In July 2019, Tesla published a patent that aimed to improve the wiring, power, and communications systems for its vehicles by reducing the amount of wires found within a car. The idea for a new wiring architecture was needed as many miles of cables can be located within a vehicle, all of which need to be installed by humans and not by machines. The installation of these power lines can take a significant amount of time when needed in excessive lengths. Thus, Tesla maintained it would be decreased from 1.5 kilometers of wire in the Model 3 to just 100 meters in the Model Y.
A Tesla vehicle’s wiring system is responsible for powering everything from turn signals and interior lights to the vehicle’s charging system. It consists of both 12-volt and 400-volt wiring, and the length of wiring needed varies from vehicle to vehicle. However, one thing remains consistent: efficient wiring is crucial for faster production speeds. However, a reduction of wiring also can contribute to reducing the vehicle’s weight as miles of power cords can be present within a car’s power infrastructure.
Reducing the wiring is something Tesla worked on when developing the Model 3, as the Model S contained around three miles of wiring to power its various systems. Tesla halved this amount of wiring with the Model 3 but aimed to decrease it even further when the Model Y was announced. Munro claimed he did not see less wiring, only a more organized wiring architecture. The new design is still an improvement from the Model 3.
Munro then suggests other strategies that Tesla could have used to increase the effectiveness of its wiring systems without using excessive amounts of wires. One of these strategies is called “communications over power,” or, more commonly, Power Line Communication (PLC). Munro explains this system reduces the number of wires by allowing for the implementation into a single power line, instead of many separate lines that all have different functions.
One of the most significant differences between the design of the Model 3 and Model Y was supposed to be its wiring system. In a video from Tesla owner-enthusiast TeslaRaj, the Model Y owner’s manual shows a single track wiring system, where the Model 3 had two tracks. The new single-track system could hint toward the overall design improvements in the Model Y wiring architecture.
Tesla’s wiring design was improved through a more organized harness setting within the Model Y. While the amount and length of the wiring system appeared to be the same according to Munro, these initial changes could end up being a catalyst to a more efficient and less puzzling architecture. Of course, fewer wires would be a dramatic step toward manufacturing efficiency, but this should come with time as Munro’s suggestions just might be accounted for in future Tesla vehicles.

Tesla lands regulatory green light for Robotaxi testing in new state
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
Tesla has landed a regulatory green light to test its Robotaxi platform in a new state, less than three months after the ride-hailing service launched in Texas.
Tesla first launched its driverless Robotaxi suite in Austin, Texas, back on June 22. Initially offering rides to a small group of people, Tesla kept things limited, but this was not to be the mentality for very long.
It continued to expand the rider population, the service area, and the vehicle fleet in Austin.
The company also launched rides in the Bay Area, but it does use a person in the driver’s seat to maintain safety. In Austin, the “Safety Monitor” is present in the passenger’s seat during local rides, and in the driver’s seat for routes that involve highway driving.
Tesla is currently testing the Robotaxi platform in other states. We reported that it was testing in Tempe, Arizona, as validation vehicles are traveling around the city in preparation for Robotaxi.

Tesla is also hoping to launch in Florida and New York, as job postings have shown the company’s intention to operate there.
However, it appears it will launch in Nevada before those states, as the company submitted its application to obtain a Testing Registry certification on September 3. It was processed by the state’s Department of Motor Vehicles Office of Business Licensing on September 10.

It will then need to self-certify for operations, essentially meaning they will need to comply with various state requirements.
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
CEO Elon Musk has stated that he believes Robotaxi will be available to at least half of the U.S. population by the end of the year. Geographically, Tesla will need to make incredible strides over the final four months of the year to achieve this.
Tesla is set to improve a critical feature that has not been present in older vehicles with a new update.
Tesla vehicles feature a comprehensive suite of driver assistance features, some of which aid in driving itself, while others support the vehicle’s surroundings.
One of those features is that of Driver Visualization, and with the rollout of a new update, owners of Intel-based Tesla vehicles are receiving an upgrade that will come with a simple software update.
Tesla plans to use Unreal Engine for driver visualization with crazy upgrade
The update will provide new visualizations while Intel-based vehicles are in reverse, a feature that was not previously available, but will be with Software Update 2025.32.2.
The improvement was spotted by Not a Tesla App via TheBeatYT_evil:
Noticed something new in 2025.32.2 on my Intel MCU + USS car with FSD.
When shifting into reverse, the full FSD visualization now stays on instead of switching to the old plain autopilot visuals.

Previously, vehicles Tesla built were equipped with Intel-based processors, but newer cars feature the AMD chip, which is capable of rendering these visualizations as they happen. They were capable of visualizations when driving forward, but not in reverse, which is what this change resolves.
It is a good sign for those with Intel-based vehicles, as Tesla seems to be paying attention to what those cars are not capable of and improving them.
This was an undocumented improvement associated with this particular update, so you will not find any mention of it in the release notes that Tesla distributes with each update.

Tesla looks to make a big splash with Robotaxi in a new market
Tesla has been transparent that it is prioritizing safety, but it believes it can expand to basically any geographical location within the United States and find success with its Robotaxi suite. CEO Elon Musk said it could be available to half of the U.S. population by the end of the year.
Tesla is looking to make a big splash with Robotaxi in a new market, as the company was spotted testing validation vehicles in one region where it has not yet launched its ride-hailing service.
After launching Robotaxi in Austin in late June, Tesla followed up with a relatively quick expansion to the Bay Area of California. Both service areas are operating with a geofence that is expansive: In Texas, it is 173 square miles, while in the Bay Area, it is roughly 400 square miles.
Tesla has been transparent that it is prioritizing safety, but it believes it can expand to basically any geographical location within the United States and find success with its Robotaxi suite. CEO Elon Musk said it could be available to half of the U.S. population by the end of the year.
There have been plenty of reports out there that have speculated as to where Tesla would land next to test Robotaxi, and Nevada, Florida, Arizona, and New York have all been in the realm of possibility. These regions will need to approve Tesla for regulatory purposes before Robotaxi can officially operate.
Tesla is still testing and performing validation in several regions, and in Tempe, Arizona, things are moving forward as a Model Y with a LiDAR rig was spotted performing ground truth for the platform:

With the LiDAR unit, many followers of the self-driving and autonomy space might wonder why Tesla uses these apparatuses during validation, especially considering the company’s stance and vision-based approach.
LiDAR is used for “ground truth,” which is basically a solidification or confirmation of what the cameras on the car are seeing. It is a great way to essentially confirm the accuracy of the vision-based suite, and will not be used on Robotaxi units used within the ride-hailing suite.
The Robotaxi platform was made available to the public earlier this month, as Tesla launched its app for iOS users.
