Thanks for the reply on this. It definitely helps getting other peoples perspective on there experiences.
I am guessing we are at 80% as well, but will start to time it. So I am timing correctly the engine is on when the Green EV light is off, is that correct?
No, we don't have the turbo. We stayed away from the rx550 because of the gas milage. That had a window sticker with MPG between 26 and 28.
More info to come. Thanks again for the help.
