Tesla’s ‘Roadrunner’ cell production facility is taking form ahead of Battery Day
Tesla’s Battery Day is only a few weeks away, and as the electric vehicle community eagerly waits for the highly-anticipated event, the company’s pilot battery production line appears to be well on its way to being completed, and perhaps even ramped. This was hinted at by a recent drone flyover of Tesla’s building at Kato Road, located close to the company’s Fremont factory.
Footage taken by a Tesla enthusiast who runs the Living with Intent channel on YouTube shows that the expansion of the Kato Road facility is well on its way. Based on the short video taken of the site, it appears that much work is being done inside the building, as hinted at by the massive amount of materials that are seemingly waiting to be taken inside the facility. The extra floor that Tesla has been constructing is also showing progress since it was initially photographed early last month.
Tesla is a disruptive company that moves fast, and thus, sightings of facilities with ongoing improvements are not really new. However, the Kato Road building is quite unique in the way that it is expected to house the pilot line for Tesla’s own battery production system. Elon Musk has been pretty open about his enthusiasm for Battery Day, stating that the event will likely blow people’s minds. At the same time, the CEO also suggested that the event will include a tour of Tesla’s in-house battery cell production setup.
This cell production system is the first of its kind, as Tesla has partnered with other battery firms in the past. Panasonic is a key partner in Gigafactory Nevada, while LG Chem and CATL are partners for Gigafactory Shanghai. But while Tesla reportedly continues to work with its partners to make better batteries, the company is also hard at work developing its own cell production capabilities. This was hinted at during the 2019 Annual Shareholder Meeting, when company executives described the effort as a step towards Tesla becoming the master of its own “destiny.”
Filings to the City of Fremont suggest that Tesla’s Kato Road facilities will be utilized for the “Roadrunner” project, which refers to the company’s own custom battery cell production line. Tesla’s “Roadrunner” cells have not been discussed in depth by the company yet, but speculations and reports suggest that the batteries are next-generation lithium-ion cells that are capable of lasting a million miles. Such batteries could make a big difference for Tesla’s flagship products like the Plaid Model S and the Megapack.
Once completed, the Kato Road facility is expected to house about 45 research and development employees and up to 425 manufacturing workers that are spread through several shifts from Monday to Friday. This may allow the pilot cell production line to produce enough batteries for low-volume vehicles, perhaps like the Plaid Model S and the new Roadster. Tesla has since opened a number of job openings related to cell manufacturing that are seemingly for the Kato Road location as well. Among these job listings are Cell Engineers, Production Process Engineers, and Controls Engineers, all of which were listed as based in Fremont, California.

Tesla Cybercab is going to get some pretty substantial updates, including improvements to efficiency and a new color.
CEO Elon Musk said in a post on X on Saturday that Tesla would be working to refine the Cybercab even more, following the announcement during the week that the company would eliminate the Cybertruck lines within Giga Texas for more Cybercab manufacturing capacity.
“There are efficiency improvements coming that will allow for a 40kWh Cybercab pack,” Musk posted on X. “We will make this in liquid silver, so the colors are not too monotonous.”
There are efficiency improvements coming that will allow for a 40kWh Cybercab pack. We will make this in liquid silver, so the colors are not too monotonous.
The biggest thing most people fail to understand is that there are a very limited number of smart, dedicated people! They can only do so many things.
If we have to maintain a complex production line, supply chain and allocate engineering for Cybertruck, we can’t use those people or factory space and machinery for scaling Cybercab, which is the vehicle that will PROFOUNDLY transform the world of terrestrial transport!

A new, more efficient model of the Cybercab will be engineered, which will only help Tesla’s profitability and margins, and it also boosts the argument for why the Cybertruck should be discontinued, at least from a business perspective.
The current Cybercab that operates in the Robotaxi platform in Austin, Texas, has a 48 kWh pack, and it sounds like Musk believes Tesla is on its way to introducing a version that has fewer cells but can manage the same workload thanks to engineering efficiencies.

Musk also doubled down on the decision to prioritize Cybercab production over Cybertruck, which is a decision that has been extremely polarizing within the community, and many fans have made it abundantly clear that they are not particularly pleased with the plans.

Cybercab is obviously Tesla’s path forward in an automotive sense. It seems that Tesla is less concerned about catering to the passenger vehicle market and is more prone to focus on transforming passenger transportation in a way that prioritizes autonomy. However, this requires some sacrifice on Tesla’s end, and the Cybertruck is unfortunately a victim of this.
Cybercab holds an extremely crucial part of Tesla’s future. With the company already revolutionizing passenger transportation once, this is the next phase, and Cybercab is the path forward.

Tesla Robotaxi app update now tells riders if Cybercab is the better choice
Tesla’s Robotaxi app now shows ETAs, wait times and availability for Cybercab and Model Y.
Tesla has rolled out a new vehicle selection screen in its Robotaxi app, and it puts the numbers riders care about most in front of them before they book.
Version 26.11.0 of the app shows the estimated arrival time, the expected wait and current availability for each vehicle option on a single screen, according to a video shared by @gheeunit on X on November 7. Riders deciding between a Cybercab and a Model Y Robotaxi can now compare those figures side by side instead of picking a car first and learning how long it will take afterward.
Tesla first gave riders that choice on September 3, the day paid Cybercab rides began in Austin. The original version of the screen listed the Cybercab, which seats two, next to the Model Y, which seats four. A later build, 26.8.2, added a seating capacity indicator so groups knew which car would fit them. What it did not show was whether choosing the Cybercab meant standing on the curb a few extra minutes.

That question matters more now than it did two months ago. Tesla had 45 Cybercabs on the Texas DMV roster when rides started. By late October the state listed 573, alongside 631 Model Ys, and community trackers logged a record 1,576 Cybercab sightings across Austin on Halloween alone. With two large fleets sharing one service area, the closest car and the quickest pickup are not always the same vehicle.
Inline availability also changes what happens when demand spikes. If no Cybercab is free nearby, the rider sees that on the selection screen rather than after trying to book one.
For now the comparison is mostly an Austin feature. Riders in Dallas, Houston, Fort Worth and the Florida markets are still matched with Model Y vehicles, though Tesla said on its third quarter earnings call that Cybercab rides would launch in Dallas this month.
The update follows a steady run of smaller changes to the rider experience. Late last month Tesla brought a quiet mode that blacks out the cabin screen to Model Y Robotaxis after first testing it in the Cybercab, and it has stretched Austin service to run from 6 a.m. to 2 a.m.
The Cybercab side of that selection screen is about to get much busier. Elon Musk said this week that Tesla will wind down Cybertruck production at Gigafactory Texas around the middle of 2027 to make room for more Cybercab output, and Tesla has said it is aiming to get Cybercabs to customers by the end of this year.
Tesla has not published official release notes for version 26.11.0.
Tesla is ending Cybertruck production sometime in mid-2027, according to CEO Elon Musk.
Musk made the announcement on X last night, which came as a shock to many. He said that the Cybertruck will end production “to make room for increased Cybercab production” at Gigafactory Texas.
It is a huge blow to the fans of Tesla who have come to love the Cybertruck and identify with it as a symbol of their fandom. It has been the best-selling electric pickup, but it has had an underwhelming sales performance in terms of what was expected. This is mostly due to Tesla not meeting the prices it planned to offer the Cybertruck, as its unveiling and actual release were four years apart.

Overall, the responses were mixed. Some fans understood the move toward Cybercab production, especially as Tesla is truly pushing the autonomous future through its Robotaxi platform. However, others did not understand it.
“Damn, how many Cybercabs do you guys need?” one response read. Another said it was “Sad but understandable.”Even analyst Gary Black had responded to the news, stating he hoped Tesla planned to replace it with a traditional pickup design.
It doesn’t seem like that will be the case.
Tesla is so hell-bent on delivering autonomy and eventually providing a driverless service that owning a car seems like an arbitrary idea, according to their thesis. Instead, Cybercabs will be available to pick you up and drop you off on demand, safely, without any human help.
As a result, Tesla has thinned its lineup considerably, and one can only ask where the vehicle lineup goes from here. Eventually, it seems like Cybercab could be the only vehicle that Tesla will sell.
