"The new Stellantis inline six-cylinder engine has pretty much reached "open secret" status within the auto industry, but we've yet to see concrete plans for its introduction. Well, the wait is coming to an end. Jeep appears ready to debut its new Hemi replacement at the New York International Auto Show in April.
During a media roundtable in Chicago, Autoblog asked Jeep brand chief Jim Morrison whether he had anything to share regarding the new turbocharged engine; Morrison answered our question with another: "Are you coming to New York?" https://www.autoblog.com/2022/02/10/stellantis-inline6-new-york-auto-show-jeep/ "Now, possible reveal date provided or not, the exact specs of this mystery engine have not been officially stated. However, leaked information and patent documents give us a pretty clear picture of what it's likely going to look like. It's very likely around three liters, it very likely has two turbochargers, and it almost definitely makes north of 400 horsepower, probably more. Keep in mind, any engine set to replace the Hemi V8s in current Chrysler products is doing to have to at least provide parity when it comes to output in order to keep hardcore Mopar fans from revolting." https://www.thedrive.com/news/44258/inline-six-engine-to-replace-jeep-dodges-v8-likely-to-debut-in-april

Quote HistoryQuoted: But it is still a Chrysler. You say that, but the 3.6 v-6 is a very reliable motor. It's been around for a decade and has an excellent reputation. It replaced another good motor, the 4.0 I-6. |

They never should have killed off the 4.0. One of the most bombproof engines ever made.
ETA: first thing I would do is delete all that EGR crap. |

Quote HistoryQuoted: They never should have killed off the 4.0. One of the most bombproof engines ever made. ETA: first thing I would do is delete all that EGR crap. That's an interesting take. EGR systems have been on gasoline engines for decades, and they don't cause many problems. Deleting it would likely require thousands of dollars in hardware and tuning, and even if you somehow still think it's worth it, that stuff probably won't be available as the vendors producing it have been dick slapped hard by the EPA. |

Quietest 4.0 that I've heard. I never did anything but change the oil every 3k or so with the cheapest stuff I could find. Always a purolator filter, tho, they were on clearance at WM for $1-3, so I bought a buttload. (And they were the larger filters for the Ford Smallblocks, same gasket and diameter, crossed to a Wix 51515) |
