An all-new twin-turbo I6 that crushes the Hemi in Standard Output version
Stellantis says new engine offers more power than V8 along with improved economy
Think that the era of big gas-engine power is coming to an end? Fear not. Stellantis has just announced a new inline-six that’s designed to help boost fuel economy in its large vehicles. The engine is called Hurricane and it makes more than 500 hp.
It’s pretty big power from a 3.0L twin-turbo I6, but Stellantis is using tech like two low-inertia turbochargers, a plasma cylinder bore coating, wide-range variable valve timing, and an engine-mounted water to air charge cooler that gets its own cooling circuit.
The HO version of the Hurricane makes those big power numbers, along with more than 475 lb-ft of torque. Give credit to the 26 lbs of boost for that number, but the engine will need 91 octane to do it.
A Standard Output, or SO, version of the engine will make slightly less power. It’s still a solid performer at “more than” 400 hp and 450 lb-ft of torque, though. That’s more power and more torque than the 5.7L Hemi V8s Stellantis is currently using. More importantly, the automaker says the SO version of the engine is designed with a focus on fuel economy. Stellantis says it will use less gas and have lower emissions than competitor turbo V6 and V8 engines. And that it will still have good fuel economy when loaded up.
The Hurricane is set to become the primary engine in Stellantis vehicles in North America on the STLA Large and Frame platforms. Think Ram 1500, Jeep Wagoneer, Jeep Grand Cherokee, and a future Dodge Durango replacement. It will arrive in at least one vehicle by the end of the year.
