Conclusion: at these speeds and thermostat setting, my AC costs .073 gal/hr, or about 20 cents per hour. Pretty cheap! Can we conclude that setting your thermostat to 58F cost you an extra 50 cents an hour?

Thanks for your results too! I was hoping to run another set of tests soon going from say 30-55mph - your 85mpg at 42mph is impressive! Did you use CC for this?

Thanks also for the 20 cents/hour figure - puts things in perspective. We will be making a 16 hour trip to Disney this fall and I am just fine "paying $3.20" to keep my Wife/kids happy with AC when needed.

I think you might conclude that running the AC at 58F will cost you 50 cents per hour - if doing about 55mph. At 70mph, it seems you are already working the ICE harder and the AC wont cost as much in that case.
