The Buick brand has a tiny little bit of an elderly image in its native USA – but this brand new Riviera Concept that’s just debuted at the 2013 Auto China Shanghai Motor Show should set that right in an instant.

With plug-in hybrid power, sultry looks and the biggest set of gullwing doors we’ve ever seen – not to mention that classic Riviera nametag – it’s looking to give Buick a serious shot of youth appeal.
