Unlike the Soul, the Koup never had an "Iconic" design that Kia would be afraid to mess with.
A coupe version of a sedan should be much more than a 2 door version of that car.
Seems that Hyundai/Kia isn't getting that yet. As the Elantra Coupe is similarly boring and invisible.
Even, Honda is trying harder with the Civic. Where the coupe doesn't not look like a 2 door version of the sedan.
