I can't speak to how it drives, but I saw one today and it's dimensions are pretty close to those of my gen II Prius. A quick check online indicates that's it's within a couple inches across the board, which makes sense.

If dressing up a hybrid as an SUV and splitting the kamm back between the top and the bottom instead of mostly dropping from the top sells more high mpg cars, more power to Kia!
