Is The Gen 3 Mopar HEMI Engine Making a Comeback? Rumors Hint the Engine Platform Could be Back in Production By Summer 2025

It was about two years ago when word came from Mopar that production of the popular Challenger and Charger models would cease after the 2023 model year, but also the well known Gen 3 HEMI platform engines. 2024 would usher in a smaller engine focus, as well as electric car discussions. But now, the rumor mill is swirling hard about the V-8 HEMI coming back to production as early as June 2025.

The engines are rumored to be using the Gen 3 architecture, and could have some minor tweaks and/or improvements as production ramps up. The base 5.7-liter, 6.4-liter Apache and supercharged 6.2-liter Hellcat are all rumored to be making a possible comeback.
