Wouldn't it be smart to switch all models to the 100kWh battery and thereby lowering the cost of unnecessary manufacturing complexity?

Isn't Tesla using the insight of the big O notation to reduce manufacturing complexity by keeping the BOM parts as low and as simple as possible?

I think two things:

- The battery packs are already created of modules.

- battery manufacturing capacity might be the limit to growth of tesla as a company (cars, trucks, semis, utility power)

Since the model S is bumping up to 400 mile range right now, the smaller more energy-efficient model 3 would easily surpass it.

If 75kwh gets 322 miles, using dumb math gives 429 miles from 100kwh.

Now ludicrous... I wonder if the model 3's permanent magnet motors could handle it or would they need to be upgraded.

Model 3 motors could handle it. It’s what they swapped out the front motors on the S and X Raven powertrains for.

Cell manufacturing is currently the limit, especially for utility storage (which Musk said demand for is tremendous on the last earnings call), but Tesla has a new battery partner (China based CATL) that has the capacity necessary for the Class 8 Semi project.

The evidence for this is pretty weak right now. This "greentheonly" posted in February that Tesla removed the KWh rating from Model S/X battery labels though. Considering previous occasions with Osborne effect it'd be a smart way for Tesla to switch to newer batteries ahead of "Battery Day".

The front motors were added to the S and X for efficiency, not power.

The internal-cost difference between 75kWh and 100kWh might be higher than the cost having two pack sizes
