Hi all, I am trying to figure out which is the best way to gain extra mileage with limited funds. Assuming that my car is the based model = 160mile at 55mph. From reading from this forum, I've found the following (not sure how accurate). 1) Normal, car is charged to around 85% of max capacity. 2) If I drive 75% highway @ 75mph and 25% @ 30mph, I could lose extra 10% of the ideal battery. 3) If i turn on ac/heat/etc, I could lose another 10%. The originally 160mi could be done to 100 to 110mi in real world driving. So now, I want gain more miles. 1) Spend 10k and gain extra 70mi (ideal) --> 48mi (based on the above assumption) 2) Spend 3k and buy the Aerodynamic Wheel + Active Air Suspension and improve by 8 to 16mi (from #2)? Does that make any sense? From the above, it seems that the Aerodynamic Wheel + Active Air Suspension are waste of money (unless you swim in cash of course). I should just save up and get the 230mi version since it has much better $/mi cost. Help please. thanks.
