Stellantis States Turbocharged Inline-Six Engine Is In Production!

As we are about to flip the calendar forward for 2022, Stellantis has confirmed that it has begun production of its all-new 3.0-liter GME-T6 high output (H.O.) inline-six-cylinder in an updated press release about its Saltillo Engine Plant in Ramos Arizpe, Coahuila, Mexico. This is the first confirmation about the new generation of inline-six engines from the automaker, something we have talked about several times over the years. 

The name GME-T6 is due to it being based on the Stellantis Global Medium Engine or (GME) family. The T6 part of the name stands for turbocharged six-cylinder. The engine had been under development from Fiat Chrysler Automobiles (FCA) engineers for a number of years. According to our sources, the project originally began with the idea of bringing a turbocharged V6 to market, before making its way to a more well-balanced I6 layout.

Our sources have informed us that there will eventually be three different variants of the GME-T6 finding their way under the hood of several new products in the company’s pipeline. The three variants include a standard output (S.O), an H.O., and a plug-in electric (PHEV).

The H.O. version will be the first variant available and should make its way in the all-new 2022 Jeep® Grand Wagoneer (WS) first, sometime mid-2022. It will also be available in PHEV form on the Grand Wagoneer as well, allowing the ultra-premium Jeep offering to have somewhere in the ballpark of 525 horsepower. The PHEV version is said to be similar to the system found on the Grand Cherokee and Wrangler Unlimited 4xe models.

The GME-T6 will also make its way, under the hood of the next-generation Dodge Charger and Challenger muscle cars. Sources have indicated that all three variants would be offered in the duo’s lineup, ultimately replacing the 5.7-liter HEMI “Eagle” V8 and 3.6-liter “Pentastar” V6 in the process. The GME-T6 S.O. engines are said to be offered in both rear-wheel-drive and all-wheel-drive configurations for both of the next-generation cars.

Another vehicle said to adopt the all-new engine is the highly-popular Ram 1500. The turbocharged 3.0-liter GME-T6 engine would be the first all-new engine under the hood of a Ram 1500 since the EcoDiesel was introduced in 2014. It would offer the Ram half-ton lineup a new powertrain to combat the growing turbocharged I4 and turbocharged V6 offerings from General Motors (GM), Ford, and Toyota.

According to Stellantis, production of the all-new 3.0-liter GME-T6 H.O. engine began on Monday, November 22nd, 2021. We expect that production will continue to pick up closer to the unveiling of the Grand Wagoneer GME-T6 H.O. model.

The 1.2 million square foot Saltillo Engine Plant, currently manufactures the entire lineup of modern-day HEMI engines. Those engines include…

• 5.7-liter (345 cubic-inches) HEMI “Eagle” V8 for the Chrysler 300 Series (LX), Dodge Charger (LD), Dodge Challenger (LA), Ram 1500 (DT), Ram 2500 (DJ), Ram 3500 (D2), Jeep Grand Cherokee (WL) and Wagoneer (WS). 
• 6.4-liter (392 cubic-inch) HEMI “Apache” SRT V8 for the LA, LD, Jeep Wrangler Rubicon 392 (JL), and WS.
• 6.4-liter (392 cubic-inch) HEMI “Big Gas Engine” or BGE V8 for DJ and D2.
• 6.2-liter (370 cubic-inch) HEMI “Hellcat” supercharged V8 for LA, LD, and DT.
• 6.2-liter (370 cubic-inch) HEMI “Demon” supercharged V8 for LA and LD.
