Ah, good. It's higher drag than the Prius, but it's another variation on that wind-tunnel derived design language, which will hopefully gain mainstream acceptance. It doesn't matter if you're driving a minivan or a two-seater, the angle of your roof should slowly increase from the most rearward seat that accomodates tall passengers, until it ends abruptly at the rear of the car.
Conversion from concept to production will add enough drag to make this car unremarkable. I do not forsee a Kia in my garage.
