We are now on 3rd gen and the ECVT stands for electronic, which is involved with providing power to the stator winding which are similar to a solenoid or electromagnet --no voltage = no eletromagnetic field = no resistance. Also the clutch is electronic and is not engaged.
When I parked my car today at work,I did it without hitting p button and the car moved more then it has in the past when I've parked .so, I will continue using the P button before shutting it down
But sir, I have little common sense since all my other cars are 6-speed manual shift cars. ..And when the simple push of the power button automatically performs the P function, why should one need any sense to be redundant ...and yes Scott you did point this out first ..I was senslessly on the wrong page.in all honesty, its common sense to press the P button once you come to a stop and the car is in a parked position..
I even engage the emergency brake when i've driven a prius, HS250h and CT200h as well...
