It can safely be said that the Buick Riviera concept will make you forget everything you thought you knew about the American luxury brand. Buick's newest concept is full of future technology and was unveiled at the 2013 Shanghai Motor Show. Some of the futuristic tech features include GM's wireless plug-in hybrid electric propulsion system (W-PHEV), which allows the car to be charged wirelessly using a sensory recharge panel.

The Buick Riviera concept car also features four-wheel steering, gullwing doors and a suspension controlled by electromagnets. The interior houses a 4G hotspot and a holographic windshield used to display information. The concept is a design study, so don't expect to see it on the road any time soon. That being said, this new Riviera is one of the sexiest cars Buick has ever made, a fact which bodes well for the future of the brand.
