                        The Buick Riviera concept was unveiled at the 2007 Shanghai

                        The gullwing Buick Riviera concept coupe was developed 
                        with global design input by the Pan Asia Technical Automotive 
                        Center (PATAC) in China, a design and engineering joint 
                        venture between General Motors and Shanghai Automotive 
                        Industry Corporation (SAIC). The Riviera concept was engineered 
                        to accommodate a new hybrid system that will go into production 
                        at Shanghai GM. 
                         
                        To establish their styling direction for the concept, 
                        the Riviera's designers looked in part to Buick icons 
                        such as the original Y-Job Concept of 1938, the 1960s 
                        Le Sabre, Electra 225 and the Riviera coupes of the 1960s 
                        and '70s. 
                         
                        The Buick Riviera concept, features carbon 
                        fibre body panels, displaying a combination of positive 
                        and negative curves, strong front and rear identities 
                        and gullwing doors. 
                         
                        The Buick badge, hood strip, headlamps, side mirrors and 
                        rocker covers all have 'icy green' backlighting available 
                        at night, matched by backlit logo and exhausts at the 
                        rear. 
                         
                        Designers have incorporated several other design signatures 
                        from the original Riviera generation into the concept. 
                        They include the "double sweep spear" line along 
                        the bodyside and the flared tail design. The 'Shell Blue' 
                        exterior color was chosen to highlight the coupe's exterior 
                        curves. 
                         
                        The Riviera concept sits on 21-inch 10-spoke forged aluminum 
                        wheels, combining polished and satin finishes, with low-profile 
                        tires. Taking their cue from Formula One cars, the side 
                        mirrors are sweeping yet unobtrusive. 
                         
                        Inside the Riviera concept, the use of rich blue and subtle 
                        creams, representing earth and water themes, are conveyed 
                        through high-quality leather bucket seats, plush carpet and a luxurious padded steering wheel. Completing the organic feel, the roof comprises 
                        two shaded glass windows offering increased headroom natural 
                        light for occupants. 
                         
                        The three-dimensional speedometer, inspired by past classics 
                        but utterly modern in design, compliments the touchpad 
                        styled central console loosely modeled on a computer mouse. 
                        An LCD display screen crowns the central console.
