Excessive engine noise going up a grade

We just got our 2014 hybrid a week ago. When going up a relatively steep grade, the engine gets quite loud. Is this normal, and will it quiet down when it gets broken in?
This happens when going from east to west through a mountain pass. Going the other way, the grade isn't as steep going up, and the engine noise stays normal.

Loud engine has been talked about in reviews for the hybrid MKZ. I don't think that there is any problem other than it just being a bit noisy. Any updates to the situation since you posted last @nvrick
