Why no V6 Ecoboost?

[MustangSteve]

Just wondering why Ford chose to go with an Ecoboost 4 cylinder but not have an Ecoboost 6 cylinder also?

To me it seems like a reasonable choice.
Have the Ecoboost 4 cylinder for the economical minded owner.
At 310 HP, it will be outstanding for the mustang platform, no question about it.

From there I would have expected an Ecoboost 6 cylinder since ford already has experience with that engine in other applications. Presuming a similar performance per cu. inch as the 4 cylinder would give a 6 cylinder Ecoboost engine about 450 hp, just a bit above the present 8 cylinder choice.

Any ideas?

$23,600

That's the base price of the fastback before destination and delivery. That's why you don't have a twin-turbo V6. In fact, the V6 was apparently a late add back to the lineup when they realized the base price was going to be too high with the EcoBoost 4. The V6 will likely be the lowest take rate among all the engines but at least they can advertise a low starting price.

The Ecoboost 4 will be volume leader and mpg leader with the GT the performance leader. The 3.7 V6 and the EB 4 are essential to getting the volumes that Ford needed to make a business case for a new RWD platform. However, there's no way the volumes will be enough to support developing 8 different powertrain combinations when you include manual and automatic (and ten if you factor in the SVT).
