    Springtime in No Va. Temps in the 70s, 80s. Is it more efficient MPG-wise to run with windows down part-way vs AC on and windows up? I notice MPGs going down with AC on but not so much with AC off and windows partially rolled down. Anyone done an analysis on this or is there a thread? Is extra drag from down windows worse than AC on or no? Thanks much.

    We have been batting this question around for years, try a search. Here is one thread of the many available:
