KIA Sportage 1.6 T-GDi - what are your experience?

Hello together. I am in the market to replace a 2012 Audi Q3 and the Kia Sportage is a possible replacement. I am situated in europe and therefore looking at the 1.6 Mild Hybrid Version with 180 HP. What are your experiences with the car and this engine? What I don't understand: there seems like a Version with 180 HP and one with 179? Whats the difference? And can somebody please measure me the trunk? Just depth and width (between the two tirecovers). I cannot find the measurements anywhere. Next week is test-drive. Would you pay the markup for the GT Version? Thanks
