Toyota Gen-I, -II, -III Prius explained!
 

Found this presentation covering Gen-I ('97-'03), Gen-II ('03-'09), and current Gen-III ('10-'14) Prii, and thought it might be useful to others, too:

For those who need a little more help understanding the interaction between MG1, MG2, and the ICE's RPMs, this link explains it well.

Toyota Prius - Power Split Device

Also, Ford's hybrids (not sure about any other brands) use similar concepts in their transaxles (except the AWD Escape uses the same AWD setup as the conventional AWD Escape, not a separate motor in the rear like Toyota does).

What about MG3 and MG4?!?!?!?! :eek:

Not on Gen-III Prii...maybe on Gen-IV?

lots of good info here
