Tesla proudly hides ‘Octovalve’ insignia in Model Y, hints at next-gen thermal system
A number of the Tesla Model Y’s secrets are now coming to the surface, as auto veteran and teardown expert Sandy Munro continues his disassembly and analysis of the all-electric crossover. Among the most noteworthy of these secrets is the vehicle’s “Octovalve,” which could very well be an upgraded version of the Model 3’s unique “Superbottle,” which serves as the heart of the all-electric sedan’s thermal management system.
The Model 3 broke all conventions when it became evident that instead of using a different cooling system for the vehicle’s battery pack, cabin, and electronics, the all-electric sedan used one compact centralized thermal management system. Traditional automakers usually install several cooling systems in a car, since components are outsourced to different companies. Tesla opted for a different strategy with the Model 3, thanks to its vertically-integrated approach to its vehicles’ design.
Based on recent photographs taken by auto teardown expert Sandy Munro, the Model Y is also equipped with a novel thermal management system. But instead of a Superbottle, Tesla appears to have provided its latest vehicle with an “Octovalve” instead. Munro is yet to tear down and analyze the Octovalve, but just like its predecessor, it seems to be the heart of the Model Y’s cooling and heating system.
Interestingly enough, the use of the Octovalve instead of the Superbottle in the Model Y may be due to the all-electric crossover’s heat pump. Prior Teslas like the Model S, Model 3, and Model X have used electronic resistive heating systems, which are quick but less efficient than heat pumps.
This is speculation of course, but it appears that the Octovalve may be a novel way for Tesla to combine all heating and cooling systems in the Model Y in one unit. To make this possible, Tesla needed a customized, smart valve system that can perform all the cooling and heating tasks for the Model Y. Based on Munro’s previews, this definitely seems to be the case, as hinted at by the Octovalve’s own badge — an octopus with a snowflake on its head.
Elon Musk has mentioned the Octovalve in a previous tweet, while responding to a Tesla community member who inquired if the Model Y had a solution that is better than the Superbottle. Musk noted in his tweet that the Octovalve is pretty special on its own right, though he was quick to emphasize that all credit for the creation of the system is to the Tesla team, not himself.
“Yes. PCB design techniques applied to create a heat exchanger that is physically impossible by normal means. Heat pump also has a local heating loop to spool up fast & extend usable temperature range. Octavalve is pretty special too. Team did great work. No credit to me,” Musk wrote.
While discussing the Superbottle during the Model 3’s teardown, Sandy Munro stated that device, apart from giving serious technical and cost advantages for Tesla, is the very representation of the electric car maker’s vertical integration. By adopting such a device, Tesla pretty much saved on space, assembly costs, and final assembly time. Such is just not possible with other EVs such as the Chevy Bolt, an otherwise great electric car that utilizes three separate cooling systems.
“The Superbottle is a great example of how the normal automotive companies don’t work together, and Tesla does. That Superbottle crosses many lines that you can’t cross here (in Detroit). If I’m in charge of engine cooling or battery cooling, I don’t want nothing to do with cooling the cabin. And yet, we’ve got the motor cooling, the battery cooling, and electronics, all going through one little bottle that’s got some clever little ball valves that open and close to make sure that everything’s getting heated or everything’s being cooled to where it needs to be. We all thought that was the best thing in the whole damn car,” Munro commented.
Very little is known about the Octovalve and its actual functions for now, but if speculations are correct, it appears that Tesla has created something novel for its newest vehicle’s cooling and heating system once more. This bodes well for the company’s next vehicles as well, such as the Plaid Model S and Model X, the Cybertruck, the Semi, and the next-generation Roadster. Needless to say, it would be very interesting to see what vertically integrated solution Tesla creates for its next electric cars.
After launching in Austin, Texas, last week, Tesla is looking to expand the Cybercab to new parts of the United States in an effort that will see the driverless, steering wheel-less, and pedal-less vehicle chauffeur people around as part of the Robotaxi ride-hailing service.
However, the expansion will go far beyond the United States, and CEO Elon Musk revealed he hopes Europe will be the next market where Cybercab will be operational.
Musk has publicly expressed hope that Tesla’s Cybercab robotaxi will reach Europe in the near future.
On September 8, Tesla’s Chief Executive quoted a German rider who had just completed a trip in Austin, Texas, and wrote that he hoped the vehicle would not take years to arrive in Germany. Musk replied with a short but notable message: “Hopefully soon in Europe too.”

The comment arrived only days after Tesla opened Cybercab ride-hailing to the public in Austin. The two-seat vehicle has no steering wheel or pedals and relies entirely on Tesla’s Full Self-Driving software. Early passengers have described the rides as quiet, smooth, and more stylish than competing robotaxis such as Waymo.
Austin is currently the only city where members of the public can hail a Cybercab through Tesla’s Robotaxi app. The initial fleet is small; Texas registration records show only a few dozen of the purpose-built vehicles on the road.

Tesla has also been operating a larger number of conventional Model Y robotaxis in the same area, but the Cybercab itself represents the company’s first dedicated, controls-free taxi design.
Europe presents a different regulatory picture. The European Union does not permit manufacturers to self-certify vehicles the way Tesla did in the United States.
Type-approval rules and a small-series limit of 1,500 automated vehicles per type per year apply across the bloc.
Supervised Full Self-Driving has gained provisional approval in several member states through national recognition of Dutch certification, yet unsupervised robotaxi operation remains a separate and more distant step. Tesla has not announced a European launch city, date, or approval pathway for the Cybercab.
Musk himself has previously cautioned that the company does not control European regulators. In an earnings call earlier in 2026, he noted that even supervised FSD took an “immense amount of time” to clear and that unsupervised service would be “somewhat at the mercy of the governments in Europe and the EU.”
The latest social-media remark therefore functions more as an expression of intent than a timetable.
If the Cybercab eventually reaches European streets, it would mark a significant expansion of Tesla’s robotaxi ambitions beyond the United States. For now, the vehicle remains an Austin-only experience, and the gap between Musk’s hope and actual deployment will be decided by regulators rather than by engineering alone.
Tesla Cybercab might have just rolled out to the public as it entered the company’s Robotaxi suite in Austin this past week. However, the vehicle might already be on its way to becoming even better, as the company is asking riders to describe what they’d like to see improved with the Cybercab.
Tesla sent a rider experience survey to Cybercab passengers only days after paid rides began in Austin. The questionnaire asks how satisfied riders were with the overall trip. Then it requests star ratings for availability and wait time, door functionality, vehicle touchscreen, mobile app experience, seat comfort, interior space, ride comfort, cleanliness, and cargo space.
A later section asks which features riders would most like to have and allows selection of up to three items from a list that includes heated seats, ventilated seats, fully reclining seats, a tray table, a wireless phone charger, a better sound system, and more storage. Respondents may also choose none of these or write in another idea. The survey closes with a recommendation score from zero to ten.

This rapid request for input illustrates Tesla’s habit of treating early users as collaborators rather than mere customers. The company has long refined vehicles through software updates and hardware changes informed by real-world use across its passenger cars.
Collecting structured opinions so soon after commercial service started shows the same mindset applied to a purpose-built autonomous taxi. The questions themselves reveal an openness to cabin changes even after the first vehicles reached public streets, which is no surprise.
Tesla has always hoped to cater a great experience to anyone in its vehicles, which is why so many fan-requested features have made it into its vehicles.
Replies already circulating online favor reclining seats, tray tables, wireless charging, improved audio, and extra room when seats fold back.

Those preferences point toward comfort upgrades that Tesla can implement in later production batches or through cabin revisions. Because the Cybercab is designed around software first principles, many requested amenities can arrive faster than in traditional automakers.
Tesla’s willingness to survey riders immediately after launch therefore makes near-term cabin and experience improvements likely as the team reviews responses and iterates toward a more refined robotaxi people will choose daily.
Tesla Cybertruck Lead Engineer Wes Morrill revealed the company has made several changes to the all-electric pickup, which he calls a “living thing, constantly evolving and improving.”
Cybertruck is manufactured at Tesla’s Gigafactory Texas just outside of Austin, and over the past few years, Tesla has continued to make small changes to the pickup to improve everything from cost, reliability, serviceablility, and manufacturability.
“The finish line isn’t getting to production. A product is a living thing, constantly evolving and improving,” Morrill added.

Some of those changes are yet to be revealed, but perhaps the most notable one was the change Tesla made to the aero shield that sits underneath the truck. In the past, it was aluminum, but now the Cybertruck is using a self-reinforcing polypropylene.
Morrill said that the polypropylene is “stretched into fibers and then laminated into the form,” and is much more durable, much lighter, and significantly cheaper than aluminum when it is manufactured this way.
It also enabled some improvements in the geometry of the Cybertruck, improving the manufacturing around the bolts and edges, in addition to minor form changes. These all benefitted the Cybertruck in more ways than one: specifically with durability and improved drag.
I was surprised by how interested people were to find out we made a relatively benign change to the Cybertruck aero shield, a part of the car most people never even see. So I’ll share some more details.

Typically, Teslas are not necessarily identified by model year because these changes are fluid and occur when the company sees fit to implement them. It is not like other automotive companies, which usually make sweeping manufacturing changes when building a new model year.
Instead, Teslas are recognized by their “generation” or “era.” For example, those with a newer Model Y might refer to their car as a “Juniper.” This is the same with Model 3, as many refer to the new body style as the “Highland.”
Tesla’s manufacturing changes are proof of the company’s constant need to improve its products and move things forward with its vehicles. There is no need to drag one’s feet and wait until next year if the product can be made better right now, and that’s precisely what Tesla did with the Cybertruck.
