The Super Manifold is Tesla’s solution to reducing the complexity of a heat pump system for an EV. Tesla showed off its engineering chops back with the original Model Y in 2019, where it introduced a new 8-way valve (the Octovalve) and a new heat pump alongside the uniquely designed Super Manifold to improve efficiency.
Now, Tesla is launching an improved version with the refreshed Model Y - the Super Manifold V2. We got to hear about it thanks to Sandy Munro’s interview with Tesla’s Lars Moravy (Vice President of Vehicle Engineering) and Franz Von Holzhausen (Chief of Vehicle Design). You can watch the video further below.
What Is The Super Manifold?
The Super Manifold (get it, Superman?), is an all-in-one package that brings in all the components of a heat pump system into one component. The Super Manifold packs all the refrigerant and coolant components around a 2-layer PCB (printed circuit board).
This Super Manifold would normally have 15 or 20 separate components, but Tesla managed to integrate them all into one nice package. That presented Tesla with a new challenge: how to integrate a heat pump—capable of both heating and cooling—into a single, efficient platform?
Several years ago, Tesla designed the Octovalve. It combines inlets and outlets and can variably change between heating or cooling on the fly - without needing to be plumbed in different directions. This is especially important for EVs, which may need to heat the battery with the waste heat generated from the motors or the heat pump while also cooling the cabin - or vice versa.
Original Super Manifold V1.1
Tesla launched the Super Manifold V1.1 back in 2022, and it provided some minor improvements to the waste heat processing of the heat exchange system. It also tightened up the Octovalve, preventing the leakage of oils into the HVAC loop that could cause it to freeze at extremely low temperatures.
Tesla has been using the V1.1 for several years now, and it has really solved the vast majority of issues with the heat pump system that many older Model Ys experienced.
Super Manifold V2 Coming Soon
Now, Tesla is introducing the Super Manifold V2 in the new Model Y. It will improve the overall cooling capacity provided by the original Super Manifold, but unfortunately, not every single new Model Y will come with it equipped. Tesla will be introducing it slowly across the lineup and at different rates at different factories, depending on part availability.
Eventually, the Super Manifold V2 will also make its way to other vehicles, potentially including the upcoming refresh for the Model S and Model X, but initially, it’ll be exclusive to the new Model Y. Tesla expects to have the new manifold in every new Model Y later this year.

Update: It turns out that the Cybertruck already includes the Super Manifold V2 and it’s now going to be used in some new Model Ys.

Sometimes, even with Tesla’s intensive bug-testing regime, bugs manage to make it out into the wild. In this particular case, a European user noticed that their 2024 Model 3 was using up more battery than normal while parked. Normally, they noted that the vehicle would lose about 1-2% per week; however, recently, they noticed much larger drops of 3-4% per night.
They monitored their Tesla widget and noticed the car wasn’t entering deep sleep. The widget consistently showed a recent connection time—usually within the past 45 minutes.
Fix Inbound
After discussing the issue with other Tesla owners and realizing it was somewhat widespread, they contacted Tesla Service. The service team confirmed that it was a firmware bug affecting the Telematics Control Unit (TCU), which prevented the vehicle from entering deep sleep mode.
The TCU is essentially the communications hub of your Tesla - and is mounted on the ceiling of newer vehicles such as the Model 3 and the new Model Y. It enables cellular and location services (via GPS) and also handles Wi-Fi and Bluetooth services. Tesla Service stated that this bug is planned to be fixed in update 2025.14.6, although the exact version number could change. However, they confirmed that they are aware of the issue and it is being addressed.
Not a Tesla App
When the user reached out to Tesla Service, Tesla Service responded with the following (translated from Dutch):
“It has been confirmed that this is a firmware bug. The fix is in one of the next updates. Currently, it is planned for 2025.14.6 (subject to change). Do you have any more questions?”
Potentially Region-Specific
This bug could potentially be region-specific. TCUs often require specific hardware components, such as modems, as well as specific firmware versions that support different regions and cellular providers. These enable Tesla to comply with local cellular standards and regulations and ensure that your vehicle can connect to the networks available in that particular region.
At this point, it’s not clear when the fix will roll out, but given that update 2025.14.1 has practically stopped rolling out, Tesla may be waiting to resume the rollout with update 2025.14.3 or this 2025.14.6 version.
If you’ve noticed this issue and are in a non-European nation, let us know.
There has been extensive reporting on what the long-anticipated affordable EV option would become, and we’ve seen numerous news stories mentioning that it was delayed or even arriving on time. The executive team revealed the near-term and long-term plans for Tesla’s upcoming vehicles, and there’s definitely good news to share here.
Updated Timeline
The most important piece of news is that despite all the talk of delays from supposed inside sources, Tesla has confirmed that the plan for its more affordable model remains on schedule for production to begin in the first half of 2025. Tesla’s executive team narrowed that timeline down further - and said that they expect production to kick off as soon as June and that the new model will be in the market shortly thereafter.
While the production timeline itself is on track, Tesla did note that the subsequent ramping process will likely be slower than initially hoped, citing global tariff and financial impacts as challenges to overcome to prepare its production lines.
Hybrid Production Approach
Tesla has once again confirmed that this will not be their next-generation vehicle, built using new production methods. Instead, they outlined a relatively more pragmatic approach for this new model.
Tesla will utilize aspects of both the next-generation platform as well as some parts of its current platforms (namely the Model 3 and Model Y). This means that Tesla will produce this new vehicle on the same manufacturing lines as the Model 3 and Model Y.
This strategy allows Tesla to bring the vehicle to the market more quickly, while also managing capital expenditures more efficiently by using existing infrastructure. However, Tesla’s executive team also noted that this approach, while faster, will result in fewer cost reductions than what might have been achieved with an entirely new platform and dedicated manufacturing process.
Vehicle Design
Using these existing production lines means that Tesla’s new vehicle will likely share some considerable similarities with either the existing Model 3 or Model Y. Rather than being a radically different and smaller vehicle, this new model will resemble the overall form factor and shape of Tesla’s current core offerings, while being optimized for a lower cost.
This doesn’t mean that Tesla is forgetting the overall goal here. Their ultimate goal is to reduce the initial cost of ownership and lower monthly payments for customers while maintaining a standard of excellence and safety.
Not Unboxed
Both at this Earnings Call and previous ones, Tesla has indicated that this new vehicle will not be using the innovative unboxed assembly method, at least for the time being. That relatively unique method will be developed and implemented specifically for the purpose-built Cybercab and for future vehicles on the next-generation platform.
We’re just a few days away from May, so it won’t be long before we see more about this upcoming vehicle. Stay tuned.
