That's good news on the gas mileage. I have not purchased a Pacifica yet, but plan to do so in the next 12 months, likely waiting for the 2018 model. I do drive a 2011 Dodge Durango with the Pentastar V6 engine, but an entirely different transmission (a 5 speed vs your 9 speed) than the Pacifica. Even though not the same vehicle, I do get respectable mileage on the Durango. The other day when returning from Michigan, I was seeing 26 MPG on the computer with two bikes on my hitch mounted bike rack. The conditions were mostly ideal. Now, if I drive into a stiff headwind, that will drop to 22 or 23 MPG. I have read where Chrysler is either thinking about or has it in their plans to offer a cylinder deactivation feature for the Pacifica, further increasing gas mileage performance on the highway. The point I am making here is this V6 engine is a solid performer and gets good gas mileage from my experience and from what I see others report. Chrysler has made over 5 million of these V6 engines since they went into production in 2011. By the way, I have 86,000 trouble free miles on my vehicle and intend to keep it for the next several years.
