Tesla’s Project ‘Roadrunner’ opens the doors for the Model S Plaid’s release
Documents and filings about Tesla’s facility in Kato Road, near the Fremont Factory, suggest that the electric car maker is attempting to ramp its operations on the site, which is rumored to be an in-house battery research and manufacturing facility. The project, dubbed “Roadrunner,” is expected to start producing battery cells that are created by Tesla, for Tesla vehicles. And in a way, such a project could pave the way for the release of the company’s next flagship sedan: the Model S Plaid.
Recent filings from the company to the City of Fremont indicate that Tesla has a “small-scale” battery manufacturing operation in the city. That said, the company is now planning on ramping its operations, with workers increasing to 470 people overall, 400 of which “work in shifts, such that there are 100 employees working at manufacturing and production operations at any given time, all day, every day.”
Details of project Roadrunner have not been disclosed by Tesla, though expectations are high that it would play a huge role in the upcoming Battery Day event, which is scheduled this September. Just like the Kato Road facility, official details about Battery Day are quite slim, though speculations suggest that Tesla would be discussing the development of its next-generation cells, the million-mile battery.
The implications for the million-mile battery are numerous, from electric vehicles that could outlast their internal combustion counterparts to battery storage systems that could last literal decades. But apart from these advantages, better batteries could also help electric vehicles tap into even higher levels of performance. Fortunately, Tesla actually has a vehicle lined up with such a goal in mind. It was even sent over to the Nurburgring last year, where it set unofficial records before it was brought home to the United States.
This vehicle is the Tesla Model S Plaid. The Plaid Model S is, as per Elon Musk, equipped with three electric motors that would allow the vehicle to perform even better than the already impressive Raven Model S Performance that’s available today. What is particularly interesting is that neither Tesla nor Musk has spoken about the Model S Plaid’s battery. Speculations from the Tesla community suggest that the upcoming variant of the flagship sedan could be the perfect first vehicle to carry the company’s next breed of batteries.
In a way, it would be almost poetic. The Model S is the vehicle that represents the point when Tesla hit its stride as a legitimate automaker. It is also the car that put Tesla on the map in the car industry, with the vehicle sweeping multiple awards during its tenure. It would then be unsurprising if Tesla rolls out its next-generation batteries on the pinnacle of the Model S as well.
Such a project would be a good match too, considering that the Kato Road facility is just a pilot battery cell production line, and thus, likely able to support only a limited number of vehicles per year. What’s more, Elon Musk has also suggested that the Plaid Model S’ was poised for a 2020 release, practically making it a perfect fit for the company’s project Roadrunner ramp.

Elon Musk takes latest barb at Bill Gates over Tesla short position
Bill Gates placed a massive short bet against Tesla of ~1% of our total shares, which might have cost him over $10B by now
Elon Musk took his latest barb at former Microsoft CEO Bill Gates over his short position against the company, which the two have had some tensions over for a number of years.
Gates admitted to Musk several years ago through a text message that he still held a short position against his sustainable car and energy company. Ironically, Gates had contacted Musk to explore philanthropic opportunities.
Elon Musk explains Bill Gates beef: He ‘placed a massive bet on Tesla dying’
Musk said he could not take the request seriously, especially as Gates was hoping to make money on the downfall of the one company taking EVs seriously.
The Tesla frontman has continued to take shots at Gates over the years from time to time, but the latest comment came as Musk’s net worth swelled to over $600 billion. He became the first person ever to reach that threshold earlier this week, when Tesla shares increased due to Robotaxi testing without any occupants.
Musk refreshed everyone’s memory with the recent post, stating that if Gates still has his short position against Tesla, he would have lost over $10 billion by now:

Just a month ago, in mid-November, Musk issued his final warning to Gates over the short position, speculating whether the former Microsoft frontman had still held the bet against Tesla.
“If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon,” Musk said. This came in response to The Gates Foundation dumping 65 percent of its Microsoft position.

Musk’s involvement in the U.S. government also drew criticism from Gates, as he said that the reductions proposed by DOGE against U.S.A.I.D. were “stunning” and could cause “millions of additional deaths of kids.”
“Gates is a huge liar,” Musk responded.
It is not known whether Gates still holds his Tesla short position.
Tesla made a change to the Cybertruck, and nobody noticed. But to be fair, nobody could have, but it was revealed by the program’s lead engineer that it was aimed toward simplifying manufacturing through a minor change in casting.
After the Cybertruck was given a Top Safety Pick+ award by the Insurance Institute for Highway Safety (IIHS), for its reputation as the safest pickup on the market, some wondered what had changed about the vehicle.
Tesla makes changes to its vehicles routinely through Over-the-Air software updates, but aesthetic changes are relatively rare. Vehicles go through refreshes every few years, as the Model 3 and Model Y did earlier this year. However, the Cybertruck is one of the vehicles that has not changed much since its launch in late 2023, but it has gone through some minor changes.
Most recently, Wes Morrill, the Cybertruck program’s Lead Engineer, stated that the company had made a minor change to the casting of the all-electric pickup for manufacturing purposes. This change took place in April:
We made a minor change on the casting for manufacturability in April. Our Internal testing shows no difference in crash result but IIHS only officially tested the latest version
— Wes (@wmorrill3) December 17, 2025
The change is among the most subtle that can be made, but it makes a massive difference in manufacturing efficiency, build quality, and scalability.
Morrill revealed Tesla’s internal testing showed no difference in crash testing results performed by the IIHS.
The 2025 Cybertruck received stellar ratings in each of the required testing scenarios and categories. The Top Safety Pick+ award is only given if it excels in rigorous crash tests. This requires ‘Good’ ratings in updated small and moderate overlap front, side, roof, and head restraints.
Additionally, it must have advanced front crash prevention in both day and night. Most importantly, the vehicle must have a ‘Good’ or ‘Acceptable’ headlights standard on all trims, with the “+ ” specifically demanding the toughest new updated moderate overlap test that checks rear-seat passenger protection alongside driver safety.
Tesla has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.
The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.
The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.
The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.
It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”

Tesla has used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.
It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.
