REPORT: HEMI V8 Production To Begin In August

Last month, MoparInsiders reported that Stellantis planned to restart 5.7-liter (345 cubic-inch) HEMI® V8 production at the Dundee Engine Plant (DEP) in Michigan. Since then, we’ve learned that Stellantis is targeting an August production start not just for the 5.7-liter HEMI, but the entire HEMI V8 family (other than the 6.4-liter “Big Gas Engine” that is found in the Ram Heavy Duty) at DEP.

That’s right, the HEMI’s return isn’t limited to just the 5.7-liter version. According to our sources, Stellantis also plans to restart production of the popular 6.4-liter (392 cubic-inch) “Apache” HEMI V8 and the powerful supercharged 6.2-liter HEMI HELLCAT V8s, as well.

Previously, Stellantis produced the HEMI V8 family at its Saltillo North Engine Plant in Saltillo, Mexico. That production ended in favor of the new twin-turbocharged HURRICANE I6 engines. Many believed that once existing engine stocks ran out, the HEMI V8 was finished for good.

However, following the departure of former CEO Carlos Tavares and shifting political influences, Stellantis seems to have reversed its plans. Recent leaks, as well as our many sources, have suggested that Stellantis eagerly wants the HEMI V8 back in its portfolio.

Sources have indicated that the returning HEMI V8 engines will remain based on the proven Gen 3 architecture. While most aspects will carry over, there could be notable updates or enhancements once they arrive. Additionally, a new larger-displacement HEMI variant could join the lineup in the future.

Stay tuned to MoparInsiders, as we closely monitor the exciting return of the HEMI. We’ll be bringing you updates on the engines, production timelines, and new vehicle applications as soon as they become available.
