DETROIT (WKZO) -- The latest concept vehicle from General Motors has been unveiled just before the official opening of the Shanghai Auto Show in China.
The Buick Riviera concept features gull-wing doors, a low profile, and plug-in hybrid technology. The power plant was developed by GM's Shanghai operation and the Pan Asia Technical Automotive Center.
The Riviera concept is one of 50 vehicles the automaker has on display. GM applied a trademark application for the Riviera name last May.
