Hello all, New poster here. I am/have been an aircraft mechanic for the past 30 years. I have not gotten any manuals for this car yet but plan to. My question: The ICE naturally stops and starts many times during the course of an average trip. Does the starter engage the ICE each time it starts, or does the transmission /power splitter just grab the engine when it needs it and then provide fuel and igintion to light it off? As if you are rolling a standard transmission auto and "pop" the clutch.... Seems to me if the ICE starter does engage every time, it HAS to wear out sooner than later as compared to a regular starter. Just curious. Thanks for any replies.
There is no "starter", at least not the kind you are talking about. Go to the following web site, click on "Understanding the Prius", and then read the articles to gain the understanding you seek. I think the "What's Going On As I Drive?" article is the best for a casual understanding of the prius powertrain. Graham's Toyota Prius pages

The smaller of the two motors essentially either holds it in place or gives it a nudge to invoke movement. The fact that the PSD (Power-Split-Device) is always engaged is what makes the process so simple... and smooth. http://john1701a.com/prius/prius-psd_details.htm http://john1701a.com/prius/prius-psd_animations.htm Those links provide illustrated examples of the clever stuff the PSD does.
