What I was meaning was...not much "Eco" in the Ecoboost when it is under load.
Even though the Ranger has more torque, they both did the same job just about equally. Speed, time, fuel consumption. Was assuming the Ranger would of blown the doors off the Taco, but it didn't.
The Toyota engineers have been saying for years there is no real advantage to adding turbos their gas truck engines, maybe they are right.
As you pointed out earlier, the typical gasoline turbo does okay when under moderate to little load....put it under load and not so much.
The torque delivery is definitely there though for the ecoboost family of engines. You're just going to spend a little bit more at the pump to fully utilize all that torque.
I think the main reason for the lack of towing difference between the Tacoma and Ranger is that the Tacoma's 3.5l is a well-made high-reving engine; rev it high and it will produce good horsepower....the problem I have with it, is that down low in the RPM range, the horsepower is lacking.
Honestly, I'd prefer a turbo to NA gasoline in my truck. MPG won't always be great, but you at least have the opportunity for decent half mpg if you drive moderately. I do think the Ranger's EPA ratings will turn out to be a bit inflated, similar to how they were for the F-150 ecoboost. And I'm interested to see if the initial Ranger will have the same injection and turbo issues that the early F-150 ecoboost's did.
