The upgrades were just increased production volume at the two plants for  Coyote V8s and the 6.8/7.3 V8s.   The V8s tend to be more fuel efficient under load compared to Ecoboost V6s, turbos need richer mixtures under boost and that makes an even bigger difference the heavier the load, like Super Duty trucks can tow….

If you see a v8 diesel truck with 5” exhausts “rolling coal” on other cars and pedestrians there is an 80% chance it’s a Ram and only 10% ford or Chevy.

Don’t forget Ford Super Duty buyers want V8s too.

👍 Hope new V8 is not delayed, or worse cancelled.  I’m curious to see what’s coming from Ford.   Between RAM Hemi, GM V8s, and Fords (F-150 and Super Duty), there is still significant demand for V8s.  I know it’s not a politically correct thing to say because of environment, but seems accurate or factual.

Length disadvantage is obvious to everyone, and does not require a mechanical engineering education AFAIK. 😀   On the other hand I-6 have many advantages over V6, so V6s are not a clear choice for everyone (manufacturers and buyers alike).  Somehow BMW, Mercedes, Stellantis, Mazda and others have made I-6 work with gasoline engines.  With diesel even Chevy found a way to package a 3.0L I-6 in larger vehicles.  It can be done, but whether Ford thinks it’s worth the effort and cost is a different discussion, especially with ICEVs’ future in doubt.  My point remains that while unlikely, there is “some” chance of a new V6 or I-6 engine family based on MPC architecture.

An I6 is bigger pain in the ass to add to engine packaging and crash cell issues then an I4 or a V6 would be the major issue. As for the all new Ecoboost I4-The original designs where based on Mazda JV engines from 15-20+ years ago, so they where due a major upgrade. They don't show any major improvement in MPG or performance, so like stated before-just keeping ahead of the emissions situation. The Mustang gets 1 MPG more on the highway and the Bronco actually loses 2 MPG city with the new engine (at least on Fuel Economy.gov)   The  2.7/3L Nano Ecoboosts are "new" design that only came out 10 years ago. 

Its not like the mustang hasn't had white wheels before either https://fordauthority.com/2023/03/1992-ford-mustang-convertible-summer-edition-up-for-auction/  

They’re not even close to the same, at least in the South.  

Forgot about the 14"ers!  Thanks!  

These were on 83-84 Mustang GT's.....
