Will Toyota offer upgrades when its solid state comes out?

The downside of LiFePO4 is that it's energy density is about 25% lower than regular Lithium-ion batteries. That would translate into lower range for the same physical volume. The upside of LiFePO4 is that it's much less volatile than regular Lithium. If you beat on it hard enough, you might be able to get a small fire, but it's almost impossible to make it explode. And since it's the electrolyte that burns rather than the lithium, it's not hard to extinguish it.

 

That was the funniest thing I think I have ever seen you post.

 

Not a remote chance in you know what, Toyota is way behind in Tech and is not really trying to play catchup.

 

The coolest upgradeable feature ever, was the Model S. You could buy a 60kWh sedan - for MANY $1,000's less than a 75kWh Model S.
It's actually the same battery only much bigger lower & upper buffers making less of the pack usable.
So if you purchased the vehicle in California, you could have avoided paying over 8% sales tax on the more expensive/larger (usable) battery model. But "upgrading" (relatively simple software command) was a 'service' - which does not count towards sales tax.
