You are right on target! The MPG guage will be pegged out at 100 and one to four bars of assist. Also, your Tach will be right around 1000 RPM. Once you get a hang for the car you will npow right away with out even looking when you are in EV mode. According to Honda, the car will stay in EV mode up 35 MPH. You must be on fairly flat ground and you will maintain your current speed (don't expect to accelerate in EV mode unless you are going down hill). I have been able to reach EV mode at highway speeds for short periods of time. The fastest I have been in EV mode was 77 MPH on a slight decline drafting behind an 18 wheeler. At this speed, the tach will be closer to 1500-1700 RPM. Also, I have accomplished 'long' range continious EV mode just over three miles. I will accelarate to about 5MPH over my desired speed. Then release the gas and re-engauge to reach EV mode. I try to keep a steady foot to maintain only one bar of assist, to make the battery last longer. The car will continue in EV mode over small hills but my speed will decrase (this is why I start off 5 MPH over desired speed). On the downhill the car will regain speed. This process usually takes between two to three bars on a full battery and could last longer.
