Pebble Beach 2011: Cadillac unveiled the Ciel concept

The Ciel – pronounced "C-L," the French translation for sky – is a four-seat convertible that opens a new chapter in Cadillac's design and product ascent, pushing the brand's Art & Science philosophy into a new stratum. Ciel is a new expression of Cadillac's historical grandeur, as well as a celebration of open-air motoring.
