Following yesterday's release of the Buick Invicta renderings (see details here), here are the first live shots of GM's latest concept that was unwrapped at the 2008 Beijing Show. Co-designed by GM's American and Chinese studios, the Invicta is a luxury mid-size sedan that is powered by a 250 Hp 2.0-liter turbo engine. It is said that the elegant looking Invicta will form the base for a successor to the current LaCrosse sedan. -More pics after the jump
