Going to take the Model S to Portland this weekend. Leaving from the Kirkland area and will do a straight shot down to Portland on Saturday via I-5. I'll do my best to monitor power usage and charging stops. I know the trip will be much different once Tesla gets a Supercharger on the I-5 corridor between Seattle and Portland, but until they do, we'll have to make due! Plan on driving fairly conservatively on the way down until I get a good sense of the power consumption. If things are looking good, I may open things up a bit as I get closer to Portland. Also will keep the temp in the cabin to be comfortable, but I plan on running the car in range mode on the way down. The car will have two adults and two kids, so it should be a fair test in terms of weight and luggage. I'll do a max charge on the way down to start off as well. The family and I will be staying overnight Saturday and Sunday, so it will be a good example of a tourist type weekend vacation drive to Portland from Seattle. I may not post much over the weekend, but when I get back on Monday, if I haven't posted before then I'll post info here.
