Was it uncomfortably hot in the cabin when this happened? The traction
battery and its electronics draw their cooling air from the cabin.
Continuous A/C use can cut MPGs 10%, but it is necessary in hot weather
to keep the battery system working properly.

I don't remember. Is it possible the A/C can draw from the battery at the
same rate the engine can charge it? Hasn't happened this summer and I've
driven several day with temps in the high 90's and one 65 mile trip in the
low 100's.

I've been driving my Prius for about 3,100 miles, mostly around town,
short trips of no more than 15-20 minutes, usually under 65mph. I pulse
& glide when possible, but that's a very small percentage. Here in
Augusta GA, it's been 90-106 degrees, and I use the A/C all the time.
Only rarely do I use Cruise (one 1,000-mile trip @85mph, one 500-mile
trip at 75mph). My tires are stock and at 42/40.
My best mileage for 100 miles or so has been about 49mpg, but I
generally average right at 45-46. Always between 43.5 & 46.2. BTW, I
use the MFD as I've found that hand calculation isn't as accurate for
tank-by-tank calculations. See the "Who do you believe" thread for
more, or visit greenhybrid.com.
