The first is the chunky Mohave Masterpiece and the second is the more compact SP Signature.
The Masterpiece is being described as a restyled and modernised Mohave (known as the Borrego in North America).
The stand-out features of this off-road vehicle are the new version of Kia's iconic grille, re-designed lighting, a significantly elevated body and a powerful all-wheel-drive system.
The second Kia making its debut in Seoul is the SP Signature, which is a smaller, elegant SUV. The design of these two concepts will have a general influence on all of the brand's future SUVs sold across the world.
Visitors to Kia's stand can also take a look at its electric crossover concept dubbed Imagine by Kia which was first seen at the Geneva Motor Show.
The automaker is also displaying its new R.E.A.D. (Real-time Emotion Adaptative Driving) system.
The Seoul Motor Show is open to the public from March 29 to April 7, at the Korea International Exhibition Center.
