The first all-new 2004 Chrysler Pacifica rolled off the production line on Feb. 7, 2003, at the Chrysler Group's Windsor Assembly Plant in Windsor, Ontario (Canada), defining a new segment that the automaker calls sports tourer.During the Pacifica's pre-production phase, Chrysler employees built vehicles directly on the assembly line rather than in controlled environments. This enabled them to optimize automation and tooling quickly and efficiently.The Pacifica was built under the Windsor plant's flexible manufacturing system. In addition to Pacifica, the Windsor plant produces the Dodge Grand Caravan and Chrysler Town & Country. It is the first Chrysler Group facility to produce two completely different vehicles on one assembly line. Chrysler Group said it will build approximately 100,000 Pacifica units annually.
