Well, this wasn't the most miles I've driven in one day but it was the most I've driven on one charge without charging along the way. The destination was a birthday party for someone my wife knew at work. Google maps said it was 29 miles away one way plus, we went 2 miles out of our way to pick up a card, present, etc. for a total of 60 miles round trip. I thought since the car is EPA rated for 62 miles I thought "why not". But I didn't tell the wife about this for she would have insisted on a gasoline car. All of it was hilly terrain on mostly freeway on highways 580, 13 and 24. Hwy 13 has a couple of good peaks to climb over, one being 650 ft above sea level and one on hwy 24 we had a climb to 950 ft. On the downhill side I tried to maximize my regen until I was about to climb again where I would try to get up some speed for the next hill. I did have a nine mile stretch on a two lane highway with a 50 mph speed limit where I kept my speed down to 40 with no cars behind me and 45 with cars behind me. I pulled over twice to let traffic pass as on each time I had a some gasoline powered BMW's with angry looking headlights out trying to use up their fuel. At one point along the way my wife casually turned on the AC completely unaware of my fuel maximizing. I was able to turn it off later while on the two lane highway where I could crack the windows open. I was pretty happy to arrive at our destination with 9 bars remaining.
For the return trip I was already checking Plug Share for some possible charging along the way. There wasn't a lot along the way but my plan B was to curve out of the hills at some point and descend into Oakland where there would be some familiar places to charge. But luckily I didn't need to. I used the same fuel maximizing techniques going 50 to 55 mph up hill and 60 mph downhill while on the freeways. I arrived home with 2 bars remaining and a blinking gasoline pump indicator. All this in a 62 mile range electric car. With 2 bars remaining I could have gone another 8 miles, right! How about that?
