Stellantis is currently manufacturing 5.7-liter Hemi engines for the Ram 1500 at its Saltillo North Engine Plant in Mexico, according to a newly leaked internal document. The same document reveals a production target of 630 engines per day by July, further confirming the return of the popular V8. The company plans to shift production to its Dundee Plant in Michigan after retooling is complete.
The leaked image clearly outlines Stellantis’ goal: “Hemi – Plan to attain 630jpd by July’25 to support 5.7L DT.” This aligns with earlier reports suggesting Hemi production would return to the U.S. mid-summer. Though past updates hinted at a domestic revival, the new data indicates Mexico is currently handling the bulk of the manufacturing.
Despite some belief that Hemi engines were phased out, production never fully stopped. The Dodge Durango still features the engine, and the Ram 2500 heavy-duty truck continues to utilize it. Just a month ago, Stellantis’ Canadian CEO hinted at the engine’s return, stating that customer satisfaction is a priority and suggesting fans should “stay tuned.”
We now have two clear updates: the 5.7-liter Hemi is officially back in production, and it’s being installed in the Ram 1500. Previous predictions, including internal emails from earlier this year, anticipated this move. Additionally, sources report that Hemi-equipped Ram 1500 test vehicles are already being spotted around Stellantis’ corporate facilities.
Production Site Details and Future Shift
As per sources like TK’s Garage and Butter Da Insider on YouTube, the initial production is taking place in Mexico. However, a transition to the U.S. is planned. One insider noted, “The Hemi is expected to move to America,” but added that retooling could take several months. This aligns with earlier reports pointing to the Dundee Engine Plant in Michigan as the engine’s future home. Whether this move happens in August or gets postponed remains uncertain.
Possible Charger Comeback
Fans are also speculating about the Hemi’s return to the Dodge Charger. Although there is no official confirmation yet, circumstantial signs are emerging. TK’s Garage shared an image showing modified Chargers with altered firewalls, potentially indicating early experiments to accommodate the Hemi V8.
While this fuels hope among enthusiasts, nothing is certain until Stellantis issues an official statement regarding the Charger’s engine lineup.
