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.
Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.
Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.
The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.
Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:
- Heated/Ventilated Front Seats with Powered Thigh Cushion
- Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
- Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
- Improved Airflow, Increased Efficiency, More Range
- 89 cubic feet of trunk space
- Upgraded Acoustic Glass and Suspension to Minimize Road Noise
- Adaptive Damping for a Smooth, Stable Ride
- Staggered Tires for Enhanced Grip
- Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
- 16″ First Row and 8″ Second Row Touchscreens
- 19-Speaker Immersive Tesla Audio
- 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats
- FSD Supervised and Integrated Grok AI
Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:
- Door Trim Puddle Lights
- Suede Dashboard Wing
- Exterior and Interior Badging
- Floor Mats
- Sill Plates
The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.
Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.
Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.
The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.
The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.
With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.
However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.
Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.
Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.
Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.
Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.
It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.
As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.
The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.
It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.
Tesla’s ‘megacasts’ are key to massive build quality improvements
While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.
This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.
Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.
