.....again, i'm speaking about a ground up motor redesign....not bored out retreads of an existing platform, ie Vortec...there's a huge difference in development cost. A new motor platform that forms the foundation for powerplants across product lines...costs...it costs dearly...& it will not be limited to a 'niche' model. Yes, there will be variations in power output that WILL be designated to niche or specialty lines...but the engine itself in some form will find it's way into Ford's marquee product, the F-150. It's no secret Ford has been having financial difficulties....if you think the beancounters at Ford would okay massive new engine development costs only to have that investment hamstrung by limiting it's potential market you're dreaming. If you are doubting the existence of the 6.2 as a new motor platform period, that's a whole different ball of wax. I say there are pretty much irrefutable financial bottom line arguments to say that if the new motor platform exists...then the F-150 will see it....period.

 

Okay making the assumption that you really do get 15 mpg in a v6 when my 5.3l Chevy gets 17-18 with a 6" lift... and assuming that gas and diesel are the same price, you would still round up a whopping savings of $2,500 after 100,000 miles of driving. Almost 50% of the cost difference of the upfront capital investment of purchasing a diesel using the most conservative assumptions possible. You're probably one of those people that argues that the Toyota Prius is a good investment - better find a good accountant.
