We finally have official information about the new turbocharged six-cylinder engine that should be coming soon to a Jeep, Ram, or Dodge near you. You may have heard this engine also referred to as the “Tornado” power plant. Stellantis news release shows the new 3.0-liter GMET6 HO engine on the official list, and it says this new engine started production on November 22, 2021.

[Updated on Dec 29, 2021] Since we published this story, the Stellantis North America manufacturing update press release was updated to remove references GMET6 HO engine. We will update the story once we hear any more news.

Here is the info from the Stellantis press release.

The GMET6 codename stands for ‘Global Medium Engine Turbo 6’. We still don’t know much about this powerplant, but some patent applications and charts suggest it may be a straight-6 orientation gasoline-powered engine. Now, we have official confirmation that it will have a 3.0-liter displacement. We still don’t know how much power it may produce, but Stellantis adds the HO designation to this engine. This is most likely the “High Output” designation.

Here is some information that may point to the design of the Tornado engine. This shows a straight-six twin-turbo configuration.

If this engine is slated for the likes of the Ram 1500, Jeep Grand Cherokee, Wagoneer, Dodge Durango, and other vehicles – it may need to produce in the neighborhood of 400 horsepower and 500 lb-ft of torque. This is the current benchmark set by the 3.5-liter twin-turbo V6 EcoBoost from Ford.

The official release has information about other engines as well! There is mention of an upgraded 3.6-liter Pentastar V6 and a PHEV version of the 3.6-liter Pentastar V6. Yep, a plug-in hybrid version of the Pentastar.
