Pictured from above, the shadowy teaser hints at a curvaceous coupe design finished in a golden huge.
The concept features traditional coupe proportions, with a long bonnet and a back-set cabin, dominated by a wrap-around glasshouse.
Kia has revealed little else about the concept, although it has confirmed a 2+2 seating arrangement in the cabin.
The carmaker says its new concept will deliver "head-turning looks whilst providing superb driving enjoyment whether on the road or at the track”.
The new Detroit-bound concept was designed and built at Kia's design centre in Irvine, California, where Kia's popular Sportage SUV was also conceived.
While the concept appears to be a two-door model, it is also possible that this new showcar will preview a production version of the popular GT four-door coupe, revealed in 2011.
Reports suggest the GT will make a production debut in 2016, although it is unclear if it will retain its current styling or preview a new design language
Recent spy photos add credence to these reports, hinting at a new family wagon with styling inspired by the big concept.
