Shortly, the 3.0-liter GMET6-HO was listed at Saltillo Engine Plant as being in production.
Since many years, reports about the new six-cylinder Tornado engine from FCA Stellantis circulated on the Internet. An official announcement could be imminent, according to the appearance of the engine. A patent was filed for a turbocharged, inline-six engine. The official website of the fourth-largest automaker in the world briefly listed a “3.0-liter GMET6 HO”.
While browsing the website section dedicated to the Saltillo Engine Plant, an Allpar forum member spotted the interesting piece of information. The new Global Medium Engine Turbo Six is in production at Ramos Arizpe in Mexico since November 22. Stellantis may have started the assembly of a high output configuration by using the letters “HO”
This sounds very promising. However, has already removed the “3.0-liter GMET6 H” from the page. Stellantis will be in touch to discuss the details. In the meantime, we believe the engine in question boasts a twin-turbo setup. It is derived from the 2.0-liter four-cylinder engine.
According to what we have heard, plans are in place for the inline-six to be used in a number of North American products including the Jeep Wrangler and Gladiator as well as the Grand Cherokee, Grand Cherokee, Wagoneer / Grand Wagoneer as well as the RAM 1500. Although it is not yet known how much power the inline-six produces, an old rumor claims that the HO variant could generate more than 500 horsepower. Base version is reported to produce approximately 360 horsepower, but these numbers should be taken with a pinch of salt.
The Tornado engine launch could be the end of the V8, particularly since the inline six was allegedly designed with electrification. Stellantis would be able to provide decent power for its largest vehicles and meet increasingly stringent fuel economy regulations with a long-rumored plug in hybrid configuration.
