Because when you add a tune to the 2.7L or 3.5L Ecoboost, and then add a tune to their 5.0L, the Ecoboost still makes
More power, more torque and lower peak torque than the 5.0. On top of that in stock form the 3.5L have more power, torque and better mpg than the 5.7l hemi, and add a tune to the 2.7l ecoboost and it also out does the hemi....
So please enlighten us as to where the Ecoboost is inferior to a v8.....
"when you add a tune" - neither are now stock. And I do think the 5.0, while it has good displacement for its size, it's about where they can get it power wise due to that, and they're having reliability issues with it.
Also quoting the part in my post that you apparently missed:
"In a "truck," where to me the primary concerns are longevity, simplicity, ease of maintenance? A big engine barely working is to me, the best formula. "
Do you know who agrees with me? Ford does.
For years we heard the ecoboost believers tell EVERYONE that we were getting one in the superduty.
Why wouldn't we?
V8s are
dead.
It's not 1965 anymore.
A smaller v6 with a turbo on it is "both more powerful and gets better MPG", and the reliability and longevity will be the same because it will be the same. It also has less parts because, "2 less cylinders,
duh."
It's not more complicated in any way (so say the fans), and it's better at towing (so say the fans).
The year is 2020, and the ecoboost we got in the Superduty is? A 7.3L V8.
Damn I guess Ford doesn't know how to build one?
OR:
In the heavyduty truck segment, many of these trucks will be used as a truck for the entirety of their lives.
Pulling a landscaping trailer for every mile. Hauling dirt. You name it.
And for many years, the 5.7L Hemi, was sold in those 3/4ton trucks where the expectation was that the engine had to last a very long time under hard conditions, because being down for maintenance was dollars lost for the owner. It's a reason that some will avoid the big diesel engines if they do not need the power - the maintenance costs.
Someone like that doesn't care about stoplight to stoplight racing other trucks, nor about "but with a
chip-" he's using his Truck, as a truck, to do truck things. He doesn't care about 1.5mpg better when put-putting around town either not under load. It has to run without a fuss, for as long as possible.
A big simple V8-V10 gas engine, is what they're looking for in a gas engine for that application.
There is a Ford engineer I quoted a long time ago, I believe on this very board, did state that IIRC, they didn't put the ecoboost in the super duty because of longevity/cost simplicity, and also fuel economy under load.
Note that the people who have the special magic formula to a small V6 with a turbo on it (Because apparently this is a totally new technology) in a truck, DID NOT PUT ONE IN THEIR "THIS HAS TO DO TRUCK STUFF" TRUCK.
They had reasons for it. Good ones.
It was not an accident.
While we all know someone who has a buddy who knows a guy who has a 2014 ecoboost with 150,000 miles on it? 6 years is not a long time for an HD truck. At all. Not worth writing home about. And 150,000 miles in that time is pretty usually all highway, with nothing in the back. That is not the life of a heavyduty worktruck.
Ford would have used that ecoboost in the SuperDuty if it could have.
Their consumer base has largely bought in and is religious about it, it's an easy off the shelf technology. They wouldn't have spent a dime developing an entirely new engine in a "Dead" V8 platform, if it did not absolutely need to.
Consider yourself enlightened.
I personally enjoy having a 3/4ton truck engine in my halfton, I feel no envy whatsoever when a truck that sounds like a weedwhacker rolls by.
