I'd test-drive one. But I'd never buy the first year any new car is released.
Hope my Volt holds together for another couple of years.

From Consumer Reports:
"By Toyota’s estimates, the Prius should be EPA-rated at 57 mpg combined. The new Prius Prime should get at least a 50 percent longer all-electric range. The EPA estimates that the current Prius gets 22 miles per charge before it transitions to regular hybrid operation." (emphasis mine)

I take that to mean 22 * 50% + 22 = 11 + 22 = 33 miles.

That's a might disappointing. But it is what it is.

No mention of passive v. active management of battery temperature.

Surely they've learned by now You need active thermal battery management to get any longevity.

I do believe that in the 2022 version of the Prime its smaller battery is fan-cooled with cabin air and heated electrically.

The how and why and when of 2023, I don't find.
