The F250 did 9mpg and my F150 did 8.5mpg... That 6.2L is also an old design ... Imagine if it was the 7.3L...

Regarding engine design age, the 5.0L Coyote V8 origins date back to 1990 production as a 4.6L Modular V8, so roots are 30 years old. The 6.2L Boss V8 dates back to 2010 production, so it’s much newer by comparison. However, I’m not sure how meaningful any of this is because they’ve gone through so many revisions and upgrades through the years, particularly the Modular engine.

One detail of interest is that the 6.2L and newer 7.3L reportedly share the same 115 MM bore centers, so Ford could use some of the same manufacturing tooling as a means to lower costs. That being the case, I can see Ford possibly increasing the 6.2L up to 6.8L and not just reducing the 7.3L down to 6.8L as many have assumed.

Two things we know is that the 5.0L Coyote can’t be made much larger because of its small 100 MM bore spacing, and also that the 6.2L V8 which only goes into Super Duty pickups has been replaced in part by the optional 7.3L V8. Manufacturing volume must be so low that it’s difficult to imagine the Boss engine family remaining in production unless Ford can also use it in other vehicles like Mustang and F-150, or by upgrading capabilities to make it more desirable than the larger 7.3L.
