A 3.6 cylinder engine option was not listed although that is what I have in mine. Road noise is terrible, especially on concrete. Thought it might be the tires but my wife has the exact same tire on a 2008 Ford Escape and it is 50 to 60% quieter than my Terrain. You would think for the price of this car it would have a quiet ride.
I have the 6 cyl and only get and average of 20 mpg combined city & highway. Blind spot mirror is poorly designed
I like ride, the 6 cyl. is a lot smoother riding than the 4 cyl. Plenty of room for passengers.
Apply sound proofing to the floor.
Redesign blind spot mirror.
