isnt the ecoboost a turbo 6? theres no way in hell id want that in my mustang. IMO a mustang ALWAYS needs an option for the v8. its just what made the car what it is. Of course times are changing so maybe throw in a hybrid v8 or something that will help it get really good mpg when needed (maybe a switch like a sport and cruise mode which will change the tune for better mpg)
