Mostly commuting. I've taken the car on a few ~200 mile trips. Have noticed that mpg is very sensitive to speed. If I'm driving ~67-72 mph, I get ~42 mpg. In the mid-to-upper 70s mph, I get ~38mpg. Way more than with any other car I've owned. OF course, this is during the winter, when I have the heat blasting.
The short time I drove it with temps in 60s-70s, I was getting 60-70 mpg in the city. Didn't get a chance to take it on the highway with those temps.
This is my first hybrid, and I am currently experimenting with the different driving modes and regen to see how I can get the best mpg. I'm loving the powerflow, really nerd out to that haha.
