Kia Motors Corp. released the first renderings of its revamped K5 midsize sedan ahead of its official unveiling next month at the Seoul Motor Show.

The second-generation K5 comes five years after the brand was first introduced to the auto market.

The new design incorporates a wider look from its front radiator grille, giving the car a more sporty and powerful look, Kia Motors said in a press release.

The retained feel of the side's surface and lines from the original K5 design have been preserved, but volume has been added for a more dynamic and active atmosphere.

The back of the vehicle is upgraded with a polished concept with slimmer rear lights, a smooth character line and a solid-looking rear bumper.

"The new K5, with its world-class sporty design and a bulked-up figure, is like your dream sedan with a progressive design that's one step ahead," Kia Motors said.

The company said the vehicle will be uncloaked during the 2015 Seoul Motor Show, slated to kick off April 3. (Yonhap)
