Rumor: FCA Working on New I-6 Diesels
Engines Could be Used in ProMaster, Ram 1500, Jeep Models
The inline-six engine was thought to be a dying breed, with packaging too unwieldy for the needs of modern cars, trucks, and SUVs. However, lately we’ve seen a resurgence in interest in this tried-and-true configuration, with Mercedes-Benz, Jaguar, and others planning on switching from V-6 to I-6 configurations, and BMW sticking with the layout through thick and thin. According to Allpar.com, there could be another new addition to the I-6 family soon. The Mopar and Fiat Chrysler Automobiles (FCA) enthusiast site Allpar.com claims that Fiat Powertrain is working on a new family of I-6 diesels, possibly to replace the 3.0L VM Motori V-6 used in the Ram 1500 and Jeep Grand Cherokee, as well as possible use in the Fiat Ducato and its North American counterpart, the Ram ProMaster. Although the engines used in the Ram 1500 and ProMaster are both 3.0L, the Ram’s is a V-6 and the ProMaster engine is an I-4.
Additional details are scarce, including any information about displacement or output. It could range anywhere from 3.0L to 4.5L. Speculation is that it could be offered as an entry-level diesel for the Ram 2500 models. Fans of the Cummins I-6 used in the Ram HD model can breathe a sigh of relief. As far as we know, there are no plans to replace the popular diesel in the HD trucks. Interestingly, there is a 6.7L I-6 diesel within Fiat Industrial’s engine portfolio. However, it is not used in any on-road vehicles in the North American market.
