The Chrysler Mack Avenue plant, located at 4000 St. Jean Avenue in [[Detroit]], Michigan, has been a significant site in the American automotive industry for over a century, evolving from a producer of car bodies to a major engine manufacturing facility and, most recently, a location for assembly of the [[Jeep Grand Cherokee]]. The plant’s history reflects the changing fortunes of the auto industry in Detroit and the broader economic shifts impacting the region. Its continued operation, following substantial investment and redevelopment, signifies a commitment to manufacturing within the city.

== History ==

The site’s origins trace back to 1916, when it was initially occupied by the Michigan Stamping Company<ref>{{cite web |title=Mack Avenue Engine Plant |url=https://www.motorcities.org/locations/mack-avenue-engine-plant |work=motorcities.org |access-date=2026-02-25}}</ref>. In 1920, Briggs Manufacturing Company acquired the property and began producing automotive bodies for companies including Ford and Plymouth<ref>{{cite web |title=Mack Avenue Engine Plant |url=https://www.motorcities.org/locations/mack-avenue-engine-plant |work=motorcities.org |access-date=2026-02-25}}</ref>. Briggs played a crucial role in supplying the rapidly growing automotive industry, and the Mack Avenue plant became a central component of its operations. The plant continued under Briggs’ ownership for over three decades, contributing significantly to the production of vehicles during a period of substantial growth in automobile ownership.

In 1953, Chrysler Corporation acquired the Mack Avenue plant as part of its purchase of Briggs Manufacturing Company, gaining control of the land, buildings, and ongoing operations<ref>{{cite web |title=Detroit Assembly Complex – Mack |url=https://grokipedia.com/page/Detroit_Assembly_Complex_%E2%80%93_Mack |work=grokipedia.com |access-date=2026-02-25}}</ref>. Initially, Chrysler utilized the plant for stamping parts to support the nearby Dodge Main plant. Later, from 1991 to 1995, the “New Mack” plant was used for the limited production run of the Dodge Viper, before production was moved to the Conner Avenue Assembly Plant<ref>{{cite web |title=Detroit Assembly Complex – Mack Facts & Figures |url=https://stellantis4detroit.com/wp-content/uploads/2021/06/DAC_Mack-Facts-and-Figures-June-2021-1.pdf |work=stellantis4detroit.com |access-date=2026-02-25}}</ref>. In 1995, the old Mack plant was leveled and the entire site underwent a cleanup process<ref>{{cite web |title=Detroit Assembly Complex – Mack Facts & Figures |url=https://stellantis4detroit.com/wp-content/uploads/2021/06/DAC_Mack-Facts-and-Figures-June-2021-1.pdf |work=stellantis4detroit.com |access-date=2026-02-25}}</ref>. From 1998 to 2012, a new plant constructed on the site manufactured nearly 3 million engines<ref>{{cite web |title=Mack Avenue Engine Plant |url=https://www.motorcities.org/locations/mack-avenue-engine-plant |work=motorcities.org |access-date=2026-02-25}}</ref>. Following a period of uncertainty, Fiat Chrysler Automobiles (FCA), now Stellantis, announced plans to reopen the plant for the assembly of Jeep Grand Cherokees, beginning in 2021.
