Strange, long wooooo sound at steady speeds, ICE on

I too have noticed this "Woo" sound. We get it above 65 mph steady travel either ICE or battery. Also noticed if there is a strong cross wind on the highway. Suspect it is a resonance in the rear vent system as air is trapped in there. -
Just got my check. We also beat the EPA averages without really trying, so yes, this is a nice bonus.
