6.8L Triton V10 (NA) vs 3.5L Ecoboost V6 (TT)

The 6.8L V10, and the 3.5L Ecoboost V6, are two engines that are very similar in peak torque and peak horsepower (on paper at least).

Where I am, it is still very much an option to get the 6.8L V10 in an F-450 Regular Cab and Chassis (we use this combination with a 10ft steel dump box for work). I've driven these extensively, loaded, unloaded, towing around 5000kg, loaded with gravel, etc. These are no doubt workhorse engines, we use and abuse them and usually put close to 100000km on them in the 4-5 years we have them for. For all the years I've driven them, there have been minimal issues.

Recently my father purchased a new 2016 F-150 with the 2.7L Ecoboost, which is also an excellent engine so far. It has plenty of power and torque, more than you would imagine. When I first saw it, I looked in the engine bay and laughed. Our van had a bigger engine, and it was a pig. Then I drove it, and it blew me away. As such, I can only imagine that the 3.5L ecoboost V6 has so much more power and torque.

Having seen and driven (kind of) both engines, my question is, why aren't we seeing engines like the Ecoboost put into a super duty application? On paper they clearly have similar capabilities! Obviously at one time it would be laughable to imagine a work truck that you're towing and hauling with to have a small V6, but now with Turbos and newer technology it seems like a no brainer!

Obviously the V10 had it's day, but it was getting around 50L/100km (very bad!!) hauling loads of soil, and roughly 30L/100km empty. In this day and age, it seems like a relic, and most people are going for the Powerstroke. Don't get me wrong, I love that V10, and she's pretty quick, and she screams when loaded, but I just think a smaller turbo gas engine (maybe a 4.0L, or 5.0L) would make more sense!

The difference is the duty cycle. The V10 can handle pushing a large percentage of it's maximum power continuously, while the Ecoboost is designed more towards acceleration and then cruise.
It's the same reason why a 400hp Powerstroke won't move a semi for very long, even though it also uses a 400hp diesel.

Even if Ford were to offer a smaller GTDI engine in the superduty, it would never get any better MPG's than a large displacement gasser does now.
