We mentioned the new Buick hybrid at the Shanghai Motor Show, but Buick announced more than the LaCrosse over in China. Autoblog Chinese brought us pictures of the Buick Riviera Concept when the car was revealed at the end of April, but I think readers will still be interested in this vague-sounding "fuel-efficient" possible hybrid. GM says the " Riviera has been engineered to accommodate a new hybrid system that will go into production at Shanghai GM." Parallel? Series? Who knows?
