The Stellantis Hurricane GME-T6 engine is a twin-turbocharged straight-six engine produced by Stellantis since November 2021 at their plant in Saltillo, Mexico, and announced publicly in March 2022. The engine is designed for longitudinal applications and will fit their current vehicles that have a V6 or V8. 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. 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." The engine was developed at the Chrysler Headquarters and Technology Center in Auburn Hills, Michigan, over the course of three years. Stellantis expects the Hurricane engine to be the main internal combustion power plant for future 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. The engine made its debut in the Jeep Grand Wagoneer in 2022. It will also be available on eighth-gen Dodge Charger and fifth-gen Ram 1500 vehicles beginning in the 2025 model year.
