• Stellantis is reportedly building 5.7-liter Hemi engines for the Ram 1500 at a Mexico plant.
  • The leak also indicates that the site is aiming to build 630 Hemi engines per day by July.
  • The 5.7L Hemi V8 will eventually move to Michigan after retooling at the Dundee Plant.

A newly leaked document reveals that 5.7-liter Hemi production is still alive and well in Mexico, and it looks like the V8 will be heading into the Ram 1500 soon. Previous reports indicated that Hemi production was coming back to America, but that it wouldn’t happen until mid-summer.

The Hemi never completely left production. Dodge still puts it in the Durango, and Ram uses it in the 2500 heavy-duty truck. A month ago, Stellantis’ Canadian CEO publicly stated that the brand likes happy customers and to stay tuned when asked if the Hemi would return. Now, following previous reports, a new document seems to confirm that it’s coming back.

The document in question is a leaked image outlining Stellantis’ plans for the year. Among its details, it shows a clear production goal: “Hemi – Plan to attain 630jpd by July’25 to support 5.7L DT.” In Stellantis speak, that means 630 Hemi engines produced per day by July for the Ram 1500.

So we know two new things. First, that the 5.7-liter Hemi is back in production, and second, that it’s going in the Ram 1500. That’s something we’ve heard with varying degrees of certainty. An email from earlier this year had a similar prediction, too. On top of all this, sources indicate that there are already 5.7-liter Hemi-powered Ram 1500 test mules running around corporate Stellantis offices.

Where the Hemi’s Built (For Now)

According to the TK’s Garage and Butter Da Insider YouTube channels, the Hemi V8 for the Ram 1500 will initially be produced at Stellantis’ Saltillo North Engine Plant in Mexico. However, our source told us that “The Hemi is expected to move to America,” adding that “it would take several months to retool” for the shift. This aligns with a previous report indicating the Hemi’s eventual production at Stellantis’ Dundee Engine Plant in Michigan. Whether this shift happens in August or gets delayed until the factory is ready remains to be seen.

What About the Charger?

Naturally, some fans are wondering whether this means the Hemi will make a return in other vehicles, like the Dodge Charger. While no official documents have confirmed this, there’s some circumstantial evidence that suggests it could be happening.

TK’s Garage on YouTube has shared a photo from the factory line of what seem to be modified Chargers with altered firewalls. Could these be early signs of Dodge figuring out how to cram a Hemi V8 under the Charger’s hood? It’s certainly possible, but until we get some solid confirmation, it’s all speculation.
