FCA Developing New Inline-Six To Replace Pentastar V6?

Fiat Chrysler Automobiles is allegedly working on an inline-six engine to replace the aging Pentastar V6.

Enthusiast website Allpar claims that the inline-six will be a bespoke design rather than an existing four-cylinder with two extra cylinders. FCA engineers are also thought to be developing the engine with relatively small bores and want to restrict the inline-six’s displacement to just under 3.0-liters in order to avoid higher taxes in certain parts of the world.

In all probability, this engine will be offered in a number of different configurations. Range-topping variants will likely make use of twin-turbochargers or, perhaps, a twin-scroll turbo, for an output close to or even higher than the HEMI V8.

It remains unclear how far off the engine is from launching, but it possible that it could debut in a variant of the upcoming Jeep Wagoneer or the next-generation Grand Cherokee. The Dodge Charger and Challenger will also allegedly make use of this new inline-six and it could also become the default powertrain for Ram pickup trucks.

It’s also possible that the more exotic companies from FCA, like Alfa Romeo and Maserati, could also use a version of the engine with parts designed by Ferrari.

Note: We have contacted FCA about this report and will update this story when we hear back.

Update: FCA got back to us, simply stating that it doesn’t comment on speculation.
