At the 2007 Shanghai Motor Show, Buick debuted a concept car coupe named Riviera, based on the GM Epsilon II platform. The concept was later shown at the 2008 North American International Auto Show.
It was designed by the Pan Asia Technical Automotive Center (PATAC). The design was inspired by classic Buicks, ancient Chinese artifacts, and modern electronic icons. It includes "icy green" backlighting, Shell Blue body, gull-wing doors, a 2+2 seating configuration, and 21-inch 10-spoke forged aluminum wheels.
