Drag increases with the square of the velocity. Cd of the Saab is a lot better than an SUV box, but that doesn;t change the velocity squared dependence.
Harder tires should also get you better milage - less energy loss in flexing of sidewalls, etc, etc. The low rolling resistnace tires are worth a look if mpg is a concern.
Good discussion at http://www.atmosphere.mpg.de/enid/Information_ss/Velocity___air_drag_507.html
