Jeez what's the point Ford less HP and almost the same torque as the 3 valve V-10 in the F-53...
Likely better fuel economy and lower cost to build.
Yes Ford even admitted it will have a lower cost to build but no one knows the true mpg yet, Ford has not said a word about it..
I suspect it will only be a tad better than the V-10 at best...
Unfortunately, Ford never intended their new (and hopefully improved) V-8 engine to propel their heavy duty F53 chassis at light speed. The reason for the increase in the cubic inch displacement is so that they can run the engine in closed loop more often without needing to use high power fuel enrichment. (as much) They are hoping for a slight increase in fuel mileage at higher power settings while still using 87 octane fuel. It's kind of like being able to run a jet engine (at speed) without an afterburner.
A "tad" better fuel mileage IN CLOSED LOOP means improved emission control. It's a BIG thing for Ford to demonstrate their commitment towards emission control to the powers to be, especially in their gas guzzlers.
