Some answers and QUESTIONS: On Power Management: Should energy savings be ON or OFF? On Climate: Should Smart Reconditioning be ON or OFF? On Efficiency: Should Range Mode (i) be ON or OFF? On Efficiency: Regenerative Braking SHOULD be on Standard NOT Low, correct? The car has 1000 miles on it with 21" tires The climate control was on 78 the whole trip. No braking for the trip, no wind and mostly flat driving. Also we went up and back so whatever we went slightly up we came down ( I realize you don't get it all back though).
