Minivans available today compete within a design formula that sees them all within a couple mpg of each other in the low 20s, and then you have the 2017 Chrysler Pacifica Hybrid in a class by itself.
Release by the federal government of its 32 mpg rating in hybrid mode and 33 miles gas-free electric range puts the seven-passenger family hauler ahead of even small-engined, midsized sedans and utterly dominates minvans by every other automaker.
On Nov. 30, Chrysler issued a press release boasting some of the numbers, but it held back the 32 mpg rating in hybrid mode, and really, it was being too modest.
