I found the vent temp dropped to 40F for about 10 minutes, then slowly went up to around 55F as the cabin cooled down (with the fan set for 4 bars.) Nice!

Yup, On the way home mine went down to 40 degrees F. (Ihad eco on, a/c set to auto and 78 target temp. It decided to utilize recirc.)

This morning it was about 80 degrees F.

When I got in the car this afternoon the thermometer read 130 degrees F.

The exterior temp was around 90 degrees F.

I wonder what that 130 temp does to the battery?

Re: ECO A/C Mode impact on MPG

ag4ever — 130 degrees F (~54 degrees C) isn't too bad, seeing that the NiMH battery is well insulated by its cover, steel casing, and plastic module cases, from the car's interior heat when it is parked in the sun for a few hours only. I'm pretty sure that the battery itself was a lot cooler than this, and probably well inside its "comfort" zone.
