I don't think your description is quite right. One of the electric
motors had fixed gearing, relative to the output shaft. The other
electric motor and the ICE have variable gearing. I think that the new
Prius has discarded the principle of having only one of the motors
effectively with fixed gearing by replacing the silent belt drive to the
differential and reduction gears with a pair of V pulleys operating as a
CVT, hence the description of the new model as a CVT transmission.

(Note carefully: there is no gearbox we are informed!!!)

This appears to have been necessary because of the wider speed range
required of the final drive as the performance has been increased.
Incidentally, apparently only 1/6 of the battery capacity is actually
usable because of the necessity to achieve battery life.

Maybe IMM can inform us!!!
