The engine made its debut in the Jeep Grand Wagoneer in 2022. It was then added to the 2025 Ram 1500 mid-cycle refresh and will be added to the Dodge Charger range in late 2025.

Overview

It had been in development since 2013 by then Chrysler Group LLC, as a response to Ford’s then new EcoBoost engine. It debuted with two versions, one of standard output (SO) and one of high output (HO), both featuring a start-stop system but designed for more extensive electrification in the future.^[1]

Despite having cylinder spacing and bore and stroke in common with the FCA Global Medium Engine, and valvetrain similarities, "less than 5% of content on the new Hurricane is shared with existing engines."^[2] The engine was developed at the Chrysler Headquarters and Technology Center in Auburn Hills, Michigan, over the course of three years.^[2]

Stellantis/Chrysler Group expects the Hurricane engine to be the main internal combustion power plant for future Chrysler (brand), Dodge, Jeep, and Ram Trucks vehicles using the STLA Large and STLA Frame in the North American market and is offering its use to other automobile manufacturers. The manufacturer claims the engine is up to 15 percent more efficient than larger engines.^[1]
