JRNYC, I used Sport Mode most of the time so that I had the Aero profile at any speed. I flipped to Auto when any rain-drops were present to restore the traction control. I frankly like how the vehicle looks in Sport Mode and wish there was a button for "Aero" profile without losing the traction control. Honestly, I don't think it matters between Sport and Auto at a steady pace anyway since there's little shifting going on. I just like that nose down a little
Yea, I know, seems stupid. I have another shorter run this weekend for a family event, also on Interstate all the way, so I'll leave it in Auto and see if there is any difference. I suspect not...
