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 FSD approved for testing in Nacka, Sweden, though municipality note reveals aggravating detail
Nacka, Sweden, a municipality just a few miles from Stockholm, has given its approval for FSD tests.
Tesla has secured approval for FSD testing in an urban environment in Sweden. As per recent reports from the Tesla community, Nacka, Sweden, a municipality just a few miles from Stockholm, has given its approval for FSD tests.
A look at the municipality’s note regarding FSD’s approval, however, reveals something quite aggravating.
FSD testing approval secured
As per Tesla watcher and longtime shareholder Alexander Kristensen, Nacka is governed by the Moderate Party. The shareholder also shared the municipality’s protocol notes regarding approval for FSD’s tests.
“It is good that Nacka can be a place for test-driving self-driving cars. This is future technology that can both facilitate mobility and make transportation cheaper and more environmentally friendly,” the note read.
The update was received positively by the Tesla community on social media, as it suggests that the electric vehicle maker is making some legitimate headway in releasing FSD into the region. Sweden has been particularly challenging as well, so securing approval in Nacka is a notable milestone for the company’s efforts.
Aggravating details
A look at the notes from Nacka shows that FSD’s proposed tests still met some opposition from some officials. But while some critics might typically point to safety issues as their reasons for rejecting FSD, those who opposed the system in Nacka openly cited Tesla’s conflict with trade union IF Metall in their arguments. Fortunately, Nacka officials ultimately decided in Tesla’s favor as the company’s issues with the country’s unions are a completely different matter.
“The left-wing opposition (S, Nackalistan, MP and V) voted no to this, referring to the fact that the applicant company Tesla is involved in a labor market conflict and does not want to sign a collective agreement. We believe that this is not an acceptable reason for the municipality to use its authority to interfere in a labor law conflict.
“Signing a collective agreement is not an obligation, and the company has not committed any crime. The municipality should contribute to technological development and progress, not work against the future,” the note read.

Tesla Model 3 and Model Y named top car buys in Norway
Despite growing competition from European and Korean brands, both models stood out for their balance of price, performance, and everyday usability.
Norway’s annual roundup of the best car purchases featured Tesla’s two main sellers this year, with the Model 3 and Model Y securing top positions in their respective segments.
Despite growing competition from European and Korean brands, both models stood out for their balance of price, performance, and everyday usability. The verdict comes as electric vehicle adoption remained above 95% of new vehicle sales in the country.
Tesla Model 3 strengthens its value position
Among compact EVs, the Tesla Model 3 maintained its position as the best overall buy thanks to its strong blend of performance, efficiency, and updated features. Reviewers noted that every trim offered compelling value, especially with the all-electric sedan’s improved cabin ergonomics and the return of the turn-signal stalk, which was one of the few previous complaints among drivers.
The Model 3’s mix of long-range capability, low operating costs, and responsive handling has continued to set the benchmark for compact EVs in Norway. While competitors from Hyundai, Volkswagen, and Peugeot have narrowed the gap, Tesla’s price-to-capability ratio has remained difficult to beat in this segment, Motor.no reported.
“The Model 3 clearly offers the best value for money in the compact class, no matter which version you choose. Now it also gets the turn signal lever back. This eliminates one of the few flaws in a driving environment that many believe is the best on the market,” the publication wrote.
Tesla Model Y claims its crown
The Tesla Model Y emerged as Norway’s top family-car purchase this year. The latest refresh introduced improvements in ride quality, styling, and interior materials, allowing the Model Y to deliver a more premium driving experience without a substantial price increase.
Reviewers praised its spacious cabin, strong safety profile, and practical range, all of which reinforced its appeal for families needing an all-purpose electric crossover. The Model Y remains especially notable given its continued popularity in Norway even as Tesla faces declining sales in other global markets.
“The Model Y is back as the winner in the family class. The upgrade in the new year was even more extensive than expected. It is a slightly more elegant and significantly more comfortable Model Y that solidifies its position as Norway’s best car purchase in the most important class,” the Norwegian motoring publication noted.

Tesla Giga Berlin is still ramping production to meet Model Y demand: plant manager
Tesla Gigafactory Berlin has expanded to two full shifts, as per the facility’s plant manager, and a lot of it is due to Model Y demand.
Tesla Gigafactory Berlin has expanded to two full shifts, as per the facility’s plant manager, and a lot of it is due to Model Y demand. While registrations in some countries such as Sweden have fallen sharply this year, the company’s sales in other key territories have been rising.
Giga Berlin shifts to two shifts
Giga Berlin factory manager André Thierig told the DPA that the facility has been running two shifts since September to manage a surge in global orders. And due to the tariff dispute with the United States, vehicles that are produced at Giga Berlin are now being exported to Canada.
“We deliver to well over 30 markets and definitely see a positive trend there,” Thierig said.
Despite Giga Berlin now having two shifts, the facility’s production still needs to ramp up more. This is partly due to the addition of the Tesla Model Y Performance and Standard, which are also being produced in the Grunheide-based factory. Interestingly enough, Giga Berlin still only produces the Model Y, unlike other factories like Gigafactory Texas, the Fremont Factory, and Gigafactory Shanghai, which produce more than one type of vehicle.
Norway’s momentum
Norway, facing an imminent tax increase on cars, has seen a historic spike in Tesla purchases as buyers rush to secure deliveries before the change takes effect, as noted in a CarUp report. As per recent reports, Tesla has broken Norway’s all-time annual sales record this month, beating Volkswagen’s record that has stood since 2016.
What is rather remarkable is the fact that Tesla was able to achieve so much in Norway with one hand practically tied behind its back. This is because the company’s biggest sales draw, FSD, remains unavailable in the country. Fortunately, Tesla is currently hard at work attempting to get FSD approved for Europe, a notable milestone that should spur even more vehicle sales in the region.
