That's interesting. I'm sure every make and model has a different break even point (if there is a break even point). A more aerodynamic vehicle will likely have a lower break even point than a less aerodynamic one, and a vehicle with a larger engine will expend a much lower percentage of its power on AC than a smaller car, thus the impact will be a lot less obvious. A Pruis, for example, is probably much more effiecent with AC on than with the windows down at 50mph. I don't know why they would have choosen the worst vehicle to run their test on rather than the best, or at least a more typical, vehicle (unless of course they set it up so they could "bust" the myth).
