It took much longer at the dealer and I didn't leave Portland until 3pm. I left in a bit of a hurry to get home. There is so much to learn about the car that I didn't test all the features and many cruise control speeds. There were only a few stretches where traffic was light enough to use steady cruise control and for me to watch the computer. And sometimes that was when I would be going up an long incline, so it's pretty subjective.
Total trip was 171 miles, average mpg was 42. This included stints as high as 80
mph, so that really isn't too bad. One really needs to watch one's speed, the car is peppy and quiet, so it is easy to be going faster than you think. My mileage started going up dramatically as I slowed down and was on slower roads and more familiar turf. I leave the car to rest tonight a bit in awe. The trip back went smoothly. The car does very well on the freeway, very smooth and quiet. I was blown by the navigation system. It worked better than expected and even guided me onto the ferry and up to my island driveway. That was awesome. At times it feels like the car has a subtle background conciousness watching out so that you don't miss your turn, are nice an comfortable, adjusting systems, mirror dimming etc. and in its spare time it figures out how to manage the ICE and FE. We ended the trip stopping at the mailbox and then pulling into our rural driveway and up the hill to the house on FE. The only sound was pebble crunching under the tires and the lovely lady telling me that we had arrived at our destination and she was now concluding the session. Pretty remarkable.
