If we are still carpooling come fall I'll get some more accurate number compairasons based on my previous single person non A/C numbers from the spring
It was my assumption, based on some purportedly quasi-quantitative research, that fuel efficiency on modern cars actually suffer from running with open windows at highway speeds due to the aerodynamic effects. That you get fewer losses through running a compressor off the engine than you do from increased drag from opening windows.
Maybe my info was wrong (again...very possible), or maybe the Smart's aero package is so goofy it doesn't matter...OR...maybe you'll get better mpg with the air on and windows up.
Hmmmm...
