Keep in mind the Autolline teardown export estimated that the Gen3 process saves 30% on the cost of building a car... That might only be 30% of GA, but it is still a fair chunk of money...
The Tesla China team did a god job on Highland, but so far they haven't produced a compact design that we know about.
It is likely that just having a smaller car with lower quality components isn't an easy path to a $25,000 car, however the BYD Seagull and some other entry level Chinese cars stack up well. MG (SAIC) is also producing good cars at very good prices.
It is likely that the unboxed construction method is better path to a $25,000 car, and in turn that requires, front and rear castings, a structural battery packs, probably 48V, definitely motors without rare-earths, and possibly an 800V architecture for the motors.
The "Holy Grail" for EVs has always been price parity with ICE especially at the entry level.
At least one Chinese car company is copying the unboxed process, others will follow, It is also a good path for an EV start-up, or for a country like India wanting to establish EV production. The problem for low volume production is sourcing the castings, we may see companies that eventually specialise in supplying completed castings to a number of different customers.
Better still, Gen3 production should be lower capex and a faster ramp, especially after it is dialled in at the first factory.
Give customers good entry level EVs at price parity with ICE, the vast majority are smart enough to do the maths on the fuel savings.
Lots of good work is also being done on improving batteries, and lowering costs... by many people, in many countries, couple improving batteries with Gen3 and the EV offerings become even more compelling...
IMO most people don't realise how fast this combination can take market share and drive down global demand for oil.
