Manufacturers don't push this stuff on us because they want to. It's all driven by emissions and fuel economy regulations, which are in turn sanctioned by acts of Congress.
When Ford was asked about their upcoming Hybrid and full electric F150, they pretty much said "yes, we're pushing to meet emissions targets, but we've also never heard a customer say 'I really wish my next truck was less efficient'"
Making vehicles cleaner, smoother, and more efficient than the competition is part of the game. I know when I bought my Hemi, I specifically waited for eTorque because my day-to-day commute is all stop and go, and during TFL's towing test it was more efficient than the F150 EB. On my exact same commute, the eTorque gets 5 more miles to the gallon than my old Hemi. Even with a short commute, that's almost $200 every year. With my old commute it would be about $600. If the new Ram had the same Hemi as my 04, or worse efficiency, I would have just gotten the F150.
In other words, yes they absolutely want their vehicles to be more efficient and last longer than the old models and longer than the competition, so yeah eTorque makes perfect sense even if the Government isn't pushing for it.
Diesel emissions? That's a whole other story since you're talking about air quality and protecting the environment.. but this thread is about eTorque.
