Saltillo Engine is a Chrysler engine plant in Ramos Arizpe, Coahuila, Mexico. The factory opened in 1981. It was built as a scale model[clarification needed] of the plant at Trenton, Michigan, United States, but with more work flexibility, having only 20 job classifications rather than the 70 at Trenton.
Saltillo South Engine opened in 2010. It produces the 3.6 L Pentastar V6 engine.
