For the sake of the aftermarket, we hope it’s the last diesel Ford builds for a while, but know that won’t be the case (stricter emissions will force manufacturers to redesign again, so this most likely won’t be the case).
When a manufacturer stops making an engine, like discontinuing the 7.3L in 2003, the 6.0L in 2008, and the 6.4L in 2010, aftermarket companies, which in order to stay competitive and ahead of the curve, have to switch gears as well. While this might not seem like a bad thing, it hurts the potential for the aftermarket to see what the previous engine can really do. It only makes sense that the aftermarket surrounding the Cummins is so huge because it has utilized the same basic design for 20 years.
By the time the 6.4L completes it’s brief three model-year run, diesel innovators will be shifting gears in order to begin working on ways to get more power out of the new blue-oval diesel which, dare I say, might not even wear the Power Stroke badge anymore. Something tells us the new 6.7L will be still be called Power Stroke though.
