Buick has officially unveiled the Riviera concept at the Shanghai Motor Show.

Designed to preview the company's upcoming styling direction, the Riviera is an attractive coupe that was jointly developed by the Shanghai GM and Pan Asia Technical Automotive Center (PATAC) joint ventures. It features a stylish design that draws influence from the "dynamic nature of water." Notable highlights include a steeply raked windscreen, gull-wing doors and muscular rear fenders. Some of the styling cues will be toned down on production models, but GM confirmed the updated waterfall grille and wing-shaped daytime running lights will become a hallmark of future Buicks.

Interior pictures were not released, but GM says the model has floating front seats, jade-inlaid wood trim and aluminum accents. There's also suede upholstery and an infotainment system with 4G LTE connectivity to access real-time traffic information and weather data.

GM was coy on powertrain details but confirmed the model is a plug-in hybrid electric vehicle that can be charged via a traditional cable or a new wireless recharging system.

On the safety front, the Riviera is equipped with a forward-looking active safety system that uses 10 high-resolution cameras and 18 high-precision sensors to warn the driver about upcoming obstacles. The concept also has adaptive cruise control, night view assist, rear cross-traffic alert and an "autopilot system."
