I’ve had a plug-in Pacifica for 3 years. I like it. I don’t know if I will continue to like it out of warranty, because it has had a few problems that would have been expensive as out-of-warranty repairs. And mine only has 18k miles on it. I go through about a quarter of a tank of gas per year, now that we have an EV for long trips and just use the Pacifica around town. I wouldn’t go through any gas, but the computer insists the gas must be burned from time to time, lest it go stale. So, I keep a quarter tank of gas in it and about twice a year the computer puts it into “fuel refresh mode” which is all-gas driving.
In gas mode it gets about 31 MPG. That 44.1 mpg sounds unrealistic — maybe that was over a flat course at 45 mph? Or they started out with a fully charged traction battery so the 115 mile was 30 at infinite mpg and the rest at 31 mpg?
