Jeep Wrangler, Gladiator, Grand Cherokee, And Wagoneer Getting New Engine

Engine / 3 Comments

And it's happening sooner than expected.

CarBuzz recently reported on the demise of the Hemi V8 from the Dodge Challenger, with suggestions that a new 3.0-liter inline-six dubbed the GME T6 would replace the naturally aspirated V8 with six cylinders and turbochargers. But it seems that this engine is destined for more models within the Stellantis umbrella, as Autoevolution has uncovered documents from the Centro Ricerche Fiat indicating that the new six-pot, which has been given the working nickname "Tornado", will find use in the Jeep Wrangler, Jeep Gladiator, Jeep Wagoneer, Jeep Grand Cherokee and the Ram 1500.

The documents in question contain lists of applications of various parts, identifying the aforementioned models by their internal codes: DT (Ram 1500), JL (current Wrangler), JT (Gladiator), WL (Grand Cherokee), and WS (Wagoneer). These models are all said to use the high-output version of the Tornado engine, a 3.0-liter inline-six with turbocharged assistance, possibly with mild-hybrid integration. There's no word yet on just how much power this new engine will produce, but it's believed that in two states of tune, it will replace both the 303-horsepower Pentastar V6 and the 375-hp Hemi V8. The latter generates up to 395 hp and 410 lb-ft in the Ram 1500 with the eTorque mild-hybrid motor, so the high output version of the Tornado could generate close to those outputs.

The Stellantis press site revealed that the engine is being produced at the Saltillo Engine Plant, and that the high output version entered production on November 22, 2021. The engine is believed to be based on the four-cylinder architecture used for the Alfa Romeo Giulia, Stelvio, and all Jeep Wrangler and Grand Cherokee 4xe models. 2022 information has already been published for the Wrangler, Gladiator, Wagoneer, Grand Cherokee and Ram 1500, with no mention of the new engine. So it will either be introduced in a mid-year update, or as part of the model year 2023 updates, shortly before Stellantis switches over to electrification fully, with electric versions of all the aforementioned vehicles on the way.
