Stellantis Takes Down “GME-T6” From Its Saltillo Engine Plant Lineup!

Looks Like The Information Was Released Too Early...

This past week, Stellantis North America updated its plant information list to include the addition of its long-awaited turbocharged 3.0-liter “GME-T6” H.O. (High Output) inline-six-cylinder engine being produced at the company’s Saltillo Engine Plant in Mexico. The new GME-T6 (which is part of the Stellantis Global Medium Engine or “GME” family), has been in development for a number of years now.

The updated announcement was the first confirmation on the new engine architecture, besides a series of patents filed back in 2017 with the United States Patent and Trademark Office (USPTO) and granted in April 2019.

The internet blew up about the announcement and the future of turbocharged inline engines making their way in several Stellantis products.

Despite making headlines in the middle of the busiest holiday week of the year, the media team at Stellantis North America was quick to pull the addition to their Saltillo Engine Plant facts and information page. The move only confirmed the early announcement of the new engine, which our sources say will be debuting in the all-new 2022 Jeep® Grand Wagoneer (WS) sometime before Q3 2022.

The 1.2 million square foot Saltillo Engine Plant, currently manufactures the entire lineup of modern-day HEMI engines. That includes the 5.7-liter “Eagle”, 6.4-liter “Apache”, 6.4-liter “Big Gas Engine” or BGE, supercharged 6.2-liter “Hellcat”, supercharged 6.2-liter “Demon” HEMI engines.

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).

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. Those models use another GME engine, the turbocharged 2.0-liter GME-T4 inline-four-cylinder.

Prior to its deletion, Stellantis stated that production of the all-new turbocharged 3.0-liter GME-T6 H.O. engine began on Monday, November 22nd, 2021.
