    I am just starting my research since we just bought a 2007 Prius. I am curious if this has been done successfully.

    Which one?

    Do you mean has anyone replaced the transmission or has anyone actually replaced one of the motors from within the transmission? I guess it would be an difficult thing to do.

    The two hybrid three phase AC motor/generators are mechanically and electronically integrated into the HSD. You can't "remove and substitute" them. At any rate, where would you find a 520V three phase motor generator that runs at 90% or better efficiency to put in even if you could?

    Here are the Gen II (left) and Gen III PSD/MGs in their naked beauty:

    This shows how the Gen II is imbedded in the "transmission" housing:

    Seems like there is very little room/chance for experimentation here...
    never mind purely electrical considerations and computer control
    algorithms.

    Of course you could put yet another motor driving the rear wheels of a Prius (and another battery pack) as in a Highlander Hybrid;

    Thanks guys. Not exactly what I was hoping to see...

    In Maine, it seems nearly impossible to obtain insurance at reasonable rates on a full electric car that is not a "name brand". I was hoping to be able to utilize the Prius as a host.

    Have you considered a 2000-2006 Honda Insight? The IMA motor/generator is a standalone piece of hardware, curb weight is 1000 lbs less (aluminum!!!), and you still get EPS. Given the major problems with short service life of IMA batteries, these cars often come up for sale for $3000 or less.

    You are right of course, but the PHEV did not exist when this thread started.
