Kia has published a second teaser shot of its latest concept car called Ray which will make its global debut at the 2010 Chicago Auto Show next week. The Ray was styled in the U.S. by the Kia Design Centre America with the company claiming that it will demonstrate the design direction that would be applied in the packaging of a plug-in hybrid vehicle.

The first teaser sketch also reveals that the Ray will be a four-door saloon with a swoopy roofline, but that’s about all we have on the concept study for now.
