CNG is common in my area as are random junked Toyota’s
It appears the hydrogen tank can be replumbed for cng
There are kits to convert various Toyota motors to CNG .
The Lexus HS hybrid motor/transaxle is a drop in replacement
Hmm, possiblities and I’m told the stock transaxle makes for a great BEV sans the tax increase.
I’m always up for something unique.
Too bad the shipping is over $3000
