I love the concept of the ecodiesel. My Green Diesel Engineering tuned 2015 made 27 mpg on average over 47k miles. It made 23 mpg average when pulling my 17' deep V Lund. This was with stock exhaust and intake. If FIAT/Chrysler would have simply addressed the problems presented by this motor and its lack of longevity if not modified, I would still own one. When people think of diesels, they think hundreds of thousands of miles without issues. However, that simply isn't the case with the RAM ecodiesel unmodified. If they moved to a reliable and modestly engineered inline 4 or 6 cylinder turbodiesel that could hit the mpg without sacrificing horsepower, torque, or longevity, I'd be a customer over a 6 cylinder gasser.
EV cars/trucks are a long way from being reality for a majority of the populace. The range and charging times are simply way too long. Heck, driving a EV basically removes all efficiency provided by interstates when you have to sit at a convenience store and let the thing charge every few hundred miles. I remember the days of driving 55mph across the country and don't want to go back!
Give me the consistent power, longevity, and reliability of a big v8 any day. I don't want to hear phony exhaust tones pumped into the cab.
I also don't believe that Latin America or any other 3rd world or poorer countries are going to get on board with EVs. If you've ever been to Mexico, Costa Rica, or Nicaragua for example, the vast majority of mid-sized pickups run on diesel (See Toyota Hilux). They are going to use the cheapest and most reliable transportation for their growing economies, not hamstring them with electric standards.
