Who makes the RAM ProMaster engine?
The RAM ProMaster uses two main engines sourced from Stellantis: a 3.6-liter Pentastar V6 gasoline engine built in North America, and a 3.0-liter EcoDiesel V6 developed by VM Motori in Italy. This reflects the ProMaster’s roots as the North American version of the Fiat Ducato and the broader Stellantis powertrain network behind it.
Engine lineup and manufacturer details
The RAM ProMaster has historically offered two primary engine options. The following list identifies who makes each engine and where the powertrain comes from.
- 3.6L Pentastar V6 gasoline engine — designed and produced by Stellantis (formerly FCA) in its North American engine plants for the U.S./Canada market.
- 3.0L EcoDiesel V6 — a diesel engine developed and produced by VM Motori, an Italian engine-maker now part of Stellantis, with production tied to VM Motori’s facilities in Italy.
The availability of each engine can vary by model year and regional market, as emissions regulations and product refreshes influence fleet offerings. In practice, Ram ProMaster buyers in North America typically encounter either the gasoline Pentastar option or the EcoDiesel supplied through Stellantis’ global supply chain, reflecting the broader cross-brand engineering within the group.
Background and context
The ProMaster’s engine strategy mirrors its Fiat Ducato lineage, aligning a familiar gasoline V6 with a diesel option that leverages VM Motori’s diesel expertise. Stellantis’ ownership of VM Motori ensures that both powertrain families are part of a single corporate fleet, enabling shared components and streamlined maintenance across brands.
