Nothing new. Old news that the 2015's were getting IRS and the Eco-4 instead of a V6.
Will probably see the 5.0 get direct fuel injection at same time.
Manufactures have to do this to get their "average fleet mpg" up to the ridiculous standards accelerated under Obuma
The Turbo 4cyl SVO's Fox bodies were no slouch in their day.
The article and supposed leak only mentioned a eco four and a new six code named nano... if there is no V8 I will be horribly surprised. The F150 hasn't sold enough 5.0l models in combination with the Mustang to justify canceling the engine.
