The 6.2L will not be offered in the F150s except the Raptor (if continued) . It'll only be in the Super Duty trucks. By 2025 the EPA will have it mandatory that all 1/2 ton trucks get a MINIMUM of 25mpg. If Ford puts any diesel in the new trucks probably be the 3.2L I5. Aren't they looking at putting military grade Aluminum as part of the new trucks?
I just really hope the aluminum does not compromise safety or strength of the truck and sour the name of Ford F-series.
