Re: Anyone tried a WAI with a hybrid?
 

Yes, at least on the Escape Hybrid you can. I find that although technically the motor will start if the cat cools off, I find that more often it starts because the coolant has cooled too much first.

Re: Anyone tried a WAI with a hybrid?
 

Another thing I noticed... A lot of people on different forums say that the FEH won't go electric unless the battery is at least 50F, but after watching my battery temps last week, there were several times the engine cut out with a 44F battery. However, taking off in electric mode is nearly impossible, when you start from a stop in electric mode with a cold battery, almost as soon as you barely touch the accelerator, the engine starts.
