Hi, I am from europe and I am interested in vw bug conversion to EV.
What is your thoughts about nissan leaf donor?
Is it has some difficulties compared to AC50 ev conversion? ...

The challenge with the Leaf motor, compared to the various motors usually used for DIY conversions, is that there are no readily available parts to adapt the motor shaft to the VW transaxle input, or the motor housing to the transaxle case... assuming that you're using the VW transaxle.

You could use the whole Leaf drive unit (motor with transaxle), but it mounts very differently from the VW engine and transaxle, and sits further forward, so it wouldn't reasonably fit in the VW.

Might me good to first clarify if we are actually talking about the original, classic, beetle here, or the newer water cooled version...

Good point. I assumed original Beetle, both because that is the common conversion target, and because andrews called it a "Bug", rather than a "Beetle".

The important difference isn't air versus water cooling of the engine, but the completely different drivetrain layout (in opposite ends of the car), as well as different size and construction of the body.
