My wife and I are currently on a little getaway trip hauling our kayaks and paddleboards down to Newport, Oregon. There are no convenient charging options where we are staying, so it looks like this trip is going to be almost all on gas. The trailer and boards are pretty light, but even so are mileage is down to around 34 mpg. I am guess it is mostly aero drag. I am using hold mode most of the time, trying to hold about 35 miles of ev range. I switch back to normal mode whenever going down a long grade so as to pick up as many extra ev miles as possible. It's kind of a game and gives me something to do while on a long 5 hour trip. I really did research chaging opportunities along our route, but there really wasn't anything convenient or reliable. Glad I am in a Volt and not a Bolt. On the other hand, if we had a Tesla there would have been a number of locations to stay charged....clearly Tesla "owns" the long distance ev travel market. GM has alot of catch-up to do in this regard.
