[1] The Trenton North Engine Plant opened in 1952 and underwent a major expansion in 1969.

In 1988, Chrysler sold much of the machining equipment, as well as a license to the design, to First Auto Works of China.

The Trenton plant largely switched to the new Chrysler 3.3 engine production, while FAW continued to build the 2.2.

Daimler Chrysler reportedly invested $297 million in 2005 to expand the Trenton Engine plant to prepare to build a new 4.0 L version of the SOHC V6 and to revitalize the 3.8 line.
