[1] At the 2010 Chicago Auto Show, Kia Motors entered the green car competition with the Kia Ray, unveiling this plug-in hybrid prototype that can be electrically recharged through a standard electrical outlet.

[3] The company claims the Kia Ray can cover as many as 50 mi (80 km) without a battery charge.

[4] In its bid to be more eco-friendly, the tires are skinny and even the audio system has been designed to use less electricity.

[5] According to Car and Driver, the Kia Ray's debut at the 2010 Chicago Auto Show, "represents an ambitious confluence of style and technology, and was arguably one of the strongest traffic-stoppers at the show.

[7] The company says the prototype was designed "with lightweight and recycled materials, as well as with hexagonal roof-top solar cells embedded in the glass roof panel that power extra lighting or climate control systems".
