That’s already happened. Ford switched from the 6.8L V10 to 7.3L V8 last year on the larger E-Series Cutaways. The smaller Transit Cutaways presently get 3.5L V6, either naturally aspirated or turbocharged. There’s not much “engine” middle ground in Ford Cutaways.


My initial “guess” is that the new 6.8L V8 will probably be an aluminum-block engine to keep weight down for F-150 and particularly the Mustang. If based on 7.3L Godzilla V8, it would likely require smaller cylinder bores to increase thickness between cylinders. That “could” explain displacement reduction from 7.3 to 6.8.

Anyway, in my opinion the 7.3L is a bit too large for smaller Class Cs built on E-350 to achieve optimum fuel economy. In time maybe a 6.8L V8 will find its way into E-Series but I wouldn’t expect it. Still, for motorhomes getting 10+ MPG on the highway, a smaller engine should help a little. Problem is that it’s only about 7% smaller which isn’t much.

Accuracy of my guesses on 7.3L V8 were dismal, so these are probably off too.
