It isn't that I feel it's too big, it's that my wife feels it's too big.
The thing is it isn't all in the numbers. The proportions of the vehicle, the driver position, and the controls can all make a vehicle feel smaller or larger when they aren't that different in size. For example, an MKX and Q5 are very similar in size and the Q5 felt great while the MKX was cramped.
The HUD in the XT5 adds confidence as it pulls your eyes down the road instead of trying to watch sensors on your mirrors or images on the screen. This helps make the vehicle feel "smaller".
Of what I drove there weren't any bad cars. At the end of the day a big piece of it was what felt best for my wife, and what feels best for one person will differ for someone else.
