Eddie Sessum Report post Posted September 8, 2013 I just did the disonnect and am very encouraged. My city mileage has always been decent (low 40s), but my highway is usually mid thirties.I did a quick test drive after the disconnect and it did seem like the car goes into EV mode easier now at highway speeds and for longer periods. Keep in mind this is one quick test run, so I can't fully draw conclusions. My clock reset. I lost EV+. i also noticed that the DTE went up to like 495 initially. It was around 400 before.I did not lose my trip statistics. Try going fast enough to keep the car out of EV mode on the hwy. I get a solid 42.5-43 when I do that. usually 68 or 69 will keep it out.
