It's not the hp I would be so worried about, it's the torque. While it's possible that this 2.3T could produce enough low-end grunt, but for how long and where would it fall off a cliff?

As crazy as it sounds, combining the 2.3T EcoBoost with say a CVT would help keep the power in the power band. My wife's car which is a 2013 Subaru Outabck (A somewhat heavy crossover vehicle) Only has a 170hp N/A 4-pot. But it "feels" more powerful than it actually is due to the CVT.

People may laugh or be uncertain about CVT's, and I was too before I owned one. But I am completely comfortable with them now, I also read one of the big three was considering a CVT in the heavy duty class to gain improved mpg's.
