Never been there, but occasionally I see the inevitable bumber sticker... "I climbed Mount Dora" It's kind of refreshing to know the town doesn't take itself seriously.hyperion said:Is Mount Dora a cool place to visit in the heat of a Florida summer?

There is some additional noise in B with "full" battery in comparison with B with charging battery because the engine is spinning faster to compensate for the loss of electric motor braking. It's perfectly normal and corresponds to what would happen on a priustoric car with manual transmission."
This makes sense, except... I have questioned my Toyota dealer about this myself as I go over a mountain in my commute. By the time I get about 3/4 the way down in "B", the engine starts reving higher. I don't want to overrev so at that point I put it in "D". The Toyota person said that he had another Prius owner express this concern and said the manufacturer said the reving is to prevent overcharging of the battery. He thought it was best to go into "D" when this occurs.
Bottom line, I would not want to leave it in "B" when it begins to rev/make noise.
The engine suddenly starts to make noise like it's reving high. It could be only 3,000-3,500 RPM (can't tell since no tachometer). It never sounds like that in normal operation. It's alarming to me even though it might not actually be a damaging situation. And the head of Toyota service recommends going to D, so that's what I do, even though I still have more of a descent.RSnyder said:What do you mean by overrev? The engine will not ever spin faster than 5000 RPM (give or take a few). That's slow compared to most modern engines.
