Originally unveiled at the North American International Auto Show, the 2017 Pacifica replaces the Town & Country and features a 3.6-liter Pentastar V6 engine that is connected to a class exclusive nine-speed automatic transmission. Thanks to the modern powertrain and a 250 pound weight reduction, the minivan will return 18 miles per gallon city, 28 mpg highway, and 22 mpg combined. Compared to its predecessor, these are improvements of 5.9 percent city, 12 percent highway, and 10 percent combined.
The improvements are dramatic but the Pacifica still loses out to the Honda Odyssey which has an EPA fuel economy rating of 19 mpg city, 28 mpg highway, and 22 mpg combined. Of course, Chrysler notes the Pacifica will soon be equipped with an engine start / stop system so its fuel economy figures could climb.
Buyers looking to further reduce their fuel consumption can wait for the Pacifica Hybrid which features a plug-in hybrid powertrain that consists of a 3.6-liter V6 Atkinson cycle engine, a dual-motor electrically variable transmission, and a 16 kilowatt-hour lithium-ion battery. This setup enables the minivan to travel approximately 30 miles on electricity alone and have an estimated fuel economy rating of 80 miles per gallon equivalent (MPGe).
