The gullwing 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 has been engineered to accommodate a new hybrid system that will go into production at Shanghai GM, GM's flagship joint venture with SAIC, in 2008.
The fuel-efficient car, which will feature several technological and manufacturing advances, represents the latest achievement of GM and its partners in the promotion and development of alternative propulsion technologies in China.

Exterior Design - A Sense Of Existence, Not Anonymity
To establish their design direction, PATAC 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 Riviera design is structured around the Buick tri-shield logo, sitting proudly on a trihedral waterfall grille which is formed by three meeting planes. This takes the traditional Buick treatment to a new level of sophisticated boldness.

The logo, 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 cleverly incorporated several other design signatures from the original Riviera generation. They include the "double sweep spear" line along the bodyside and the flared tail design. In this theme, the 'Shell Blue' exterior color was chosen to elicit the right level of attention. The color is a metallic silver with light blue accents, perfectly highlighting the coupe's exterior curves.
The gullwing doors, selected for their exotic appeal, achieve an expansive entrance to the two-plus-two seating configuration. Measuring 1938 millimeters at their widest point, they add to the coupe's sleek sideline. At night, fully opened doors gently shine the "Buick" name on the ground.
The Riviera 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.
Interior Design - All About Relaxation
In a word - sanctuary. 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 and a celestial connection for occupants.
