Fiat Chrysler Automobiles is considering replacing the Pentastar V6 with a brand new straight-six engine. A source tells Allpar the new engine will be based on their new four-cylinder Global Medium Engine (GME) - what is found under the hood of the Jeep Wrangler and Alfa Romeo Giulia. This will allow FCA to build the engine alongside the four-cylinder variant.
Not many technical details are known about the engine aside from it being pegged around 2.9L to avoid taxes in certain European countries. We might expect larger displacements for trucks and SUVs. Production could take place at FCA's Dundee and Trenton, Michigan plants. It is expected that Ferrari will use a variant of this engine for Maserati vehicles. No timeframe as to when this new engine could debut.
Allpar also mentions in their report that FCA was considering adding some sort of boost to the Pentastar, but ran into issues with the size and power constraints.
