On the eve of the Beijing Motor Show ,General Motors Chairman Rick Wagoner and Design VP Ed Welburn along with their Chinese colleagues unveiled the Buick Invicta concept. Your regular Autoblog team didn't make the trek to China for this show, but our cohorts at Autoblog Chinese showed up for GM's Premier Night party to check out what will be the replacement for the current LaCrosse. The car was revealed sitting on a pool of water, perhaps implying that it is Buick's messiah, standing by to breathe new life into the brand Stateside. Buick is of course thriving in China, and some of the same team that created last year's Riviera concept participated in the styling of this new model. This design riding on the Epsilon II platform is expected to make the transition to production pretty much unscathed although the roofline might be slightly higher.
