What will happen to obsolete built-in batteries in Tesla cars? Able to replace?

Evolution goes on... and so does the power and range of batteries.
Unevitably the built-in power batteries of a Model S and X today will be far less powerfull and shorter in range than the new batteries within already 5 to 10 years. Also the electromotors will evolve. Now they are already constructing 100kWh motors, which means that the 70 - 85 and 90kWh motors are already a bit obsolete.

My question is: will it be possible to renew your old built-in batteries and/or electromotor with the newer and more powerfull versions after some years? Is that technically possible?
Or would you have to buy a totally new car?

current motors have 350kW (kW, not kWh)

old batteries can be reused in stationary applications or recycled at gigafactory. That is why crashed Model Ses has still high value if battery did not burn.

Also batteries and motors can be changed. It just costs quite a bit right now (batteries are still quite expensive). Wiring and PEM affects a lot what those new parts can offer, but capacity can increase without affecting much else.

It is quite realistic to assume a better battery will be available in the future. A new motor is not so likely as motors aren't likely to wear out very soon (few moving parts) and the rest of the car has to be built to handle a stronger motor.
As an example of better battery: Tesla's replacement Roadster batteries are 70 kWhr, replacing the original 50 kWhr. This will boost the original 244 mile range to about 400 miles (with a few other drag reduction improvements).

Just as one can replace the entire drive train in any car, the same can be done in a Tesla, so I don't get the question.

Lithium batteries are 100% recyclable. However, currently, recycling the lithium out of a battery is more expensive than generating the compound from raw material.
It's the other rare metals that are currently recycled from old lithium batteries that are viable.
Here is a link to an article which explains the lithium battery recycling process.

Electric motors routinely operate at 98-99% efficiency, and different types of motors operate in different ways. Although there are some electric motors that are less efficient.
Tesla engineers know all of the different types of motors, and which ones work the best for automobiles. They are even implementing a few tricks of physics that some people, not versed in physics, would be in disbelief.

The packs are designed to be swappable, so, in the future, you will be able to upgrade to newer battery technology, although Elon noted its not cost effectives unless there is a 10-15% improvement, IIRC.
