Kia will be using the 2007 Chicago Auto Show as the venue to debut its Rondo SX Concept. We don't have much information on the car, besides the fact that it's based on the Rondo and features a more aggressive front end with a big lower air intake and a revised rear with what we assume to be faux diffusers nestled between a pair of tailpipes. A glimpse of the driver side front wheel shows five-spoke alloy rims that are definitely not available on the current Rondo, as well. Kia says that the suspension will be tuned for performance and that there are other performance mods on the Rondo SX. The regular Rondo can be had with either a 162-hp 2.4L four-cylinder or a 182-hp 2.7L V6, so hopefully the Rondo SX will feature one of these engines pumping out more power than stock.
