The sketch shows the silhouette of a long hood and a fastback-style passenger cabin.
The design of the car was made at Hyundai's European research and development center in Rüsselsheim, Germany.
"Two strong arched curves define the silhouette of i-oniq, creating a playful contrast between the sharp character lines and soft but muscular features," Thomas Bürkle, Hyundai's European design chief, describing the i-oniq, said in a statement.
A spokesman fromHyundai Motor America declined to elaborate on the vehicle.
It has applied the "fluidic sculpture" styling to nearly its entire vehicle lineup. The swoopy lines and dramatic surface treatments of the corporate look have helped Hyundai shed its legacy of hum-drum styling and boost sales of vehicles like the Sonata and Elantra.
