Since I got the car 5 weeks ago, I've only had 3 trips longer than the EV range. One of 100 miles, one of 125 and one of 230. In all three cases, I switched to hybrid at the beginning of the trip, and started with a full charge. The two shorter trips worked great, guess o meter showed mpg of ove 50, and I still had some batter available at the end of the trip.

But on the longer trip, the battery was exhausted after ~180 miles or so, and I had to finish the trip in batter hold.

Is this normal? Was there anything I could have done on that trip to make certain that there was enough battery left for that last part of the trip to be in hybrid mode?
