We have the 2015 Terrain SLT2, one step below Denali, and it is a very nice to be in for city work and has long wheelbase to excellent highway ride. The fiancé drives it and usually sees 20 mpg idling for her work, running the AC full blast, and aggressively accelerating. On the highway over the last 50 mile average I have gotten over 32.5 mpg....with AWD. The safety sensors keep her from backing into my car but she doesn't like the lane departure and collision alert barking at her.
Coming from an tinny, oil consuming 2012 Forester this car is a Cadillac! She likes the luxuries but in a package that doesn't scream the part with chrome, yet still looks rugged.
