That seems like a natural course of events. Musk built Tesla vertically integrated because they were producing something very different, at least in a lot of the core systems and body chassis design. But now that Tesla has a few platforms, it’s all about cost reduction and volume with minor redesign and OTA software updates. Maybe sell part interest in the factories to a Foxconn or other, license the platforms (like IP) and disaggregate into design and manufacturing, with many makers leveraging the factory/car foundry and IP.
Tesla (automotive) is arguably a hybrid already as the largest single expense of the car (battery cells) are sourced three ways:
- Inhouse manufacturing (4680 cells - Cybertruck/Semi)
- Joint agreement with Panasonic for 2170/4680 cells (Gigafab Nevada is co-owned between Panasonic and Tesla) (All models)
- Purchase as a customer" LFP batteries from CATL (some Model 3/Y)
They also source a lot of 12V parts from others; it's why the Cybertruck is a hybrid of 48V and 12V architectures. Accessories are also mostly third party; example the "Tesla" floor mats are rebranded WeatherTech. However, the motors (much smaller expense than the battery) are built in-house.
On the solar side, they're "fabless" -- they use LFP batteries now in PowerWall 3 (purely outsourced), and the solar panels are from third party OEMs such as QCell.
Of course the software for everything is internally developed, but that's what makes Tesla's infotainment and electronics systems years ahead of legacy carmakers.
I don't think outsourcing any part of manufacturing would make any sense just yet. They're able to make EVs for a much lower cost than any other maker except the Chinese; adding more hands will just increase complexity and cost. Example: "
VW about 30 hours to produce one of their new ID. 3 EVs, whereas Tesla needs just 10 hours to make a single Model 3." (Note that this is the older Model 3 while the newer 3/Y take substantially less time).
