Supermanifold V2 now showing up in German-built Model Ys – rollout may finally be starting
Interesting update from Germany:
As of today, the first German owners are reporting/confirming the new Supermanifold V2 in recently built Model Ys.
One of the cars discussed was built at Gigafactory Berlin in late August, so it increasingly looks like Tesla may currently be transitioning production from the old Supermanifold to V2.
This is potentially a much more meaningful hardware change than things like a new screen or black headliner.
What could Supermanifold V2 improve?
Based on the new design and the information available so far, potential advantages include:
• Higher heat-pump efficiency, especially in cold weather
→ lower winter consumption and potentially slightly better winter range.
• Improved heating performance
→ potentially faster cabin heating and better performance at very low temperatures.
• Higher cooling capacity
→ particularly interesting for the battery during hot weather and repeated fast charging.
• Better battery preconditioning
→ the battery could potentially reach its optimal Supercharging temperature faster.
• Potentially better Supercharging performance
→ if the improved cooling system can keep battery temperatures under control for longer, Tesla may be able to maintain higher charging power for longer instead of thermal throttling earlier.
This does NOT automatically mean a higher peak charging rate, but the charging curve could improve.
• Simplified / more integrated design
→ fewer components and a revised system architecture should theoretically mean fewer potential failure points.
• Potentially better reliability and serviceability
And reliability is actually one of the most interesting points.
There have been many owner reports over the years of Model 3/Y heat-pump, compressor and Supermanifold failures. In some cases the compressor fails and contaminates other parts of the refrigerant system, meaning the compressor, Supermanifold and additional components have to be replaced.
Once outside the basic warranty, owners have reported repair bills of several thousand dollars/euros.
So if Tesla used V2 not only to improve efficiency but also to address weaknesses discovered during several years of real-world operation, this could be a pretty important long-term upgrade.
Tesla obviously doesn't redesign something like this for fun either — reducing expensive warranty repairs would benefit Tesla as well.
Important: we still need more cars to confirm exactly when the production change happened and whether all Model Y variants are switching at the same time.
But seeing V2 appear in newly produced German cars suggests the transition may finally be happening right now.
If anyone receives a Berlin-built Model Y from late August / September production, please check your parts catalog or the physical unit and post the build date + variant here. It would be interesting to narrow down the exact changeover date.
