Some graphs of temperature vs. MPG

[bwilson4web]

This comes from 3 years, 185 tanks, for a 2003 Prius:

Due to the humidity, when temperatures reach 85F, I may use the A/C. It is a driver safety issue.

I've recorded some data from trip from Huntsville, AL, to Columbia, SC, and back. A high pressure system came to Dixie and the temperatures ranged from 15F to 39F and back to 18F when I got home. Because I left at 4:00 AM and got back a midnight, there very little wind as a drove across the high pressure system. My highway mileage tracked the air density.

I would love somebody in the warmer climes posting their data, so that effect of further higher temps (> 80F) without the pesky AC factor coming in can be seen. Would FE still be climbing with temp? Would it wind down at some point? Through what mechanism?...

Look at my data above. That is WITHOUT AC usage.
