Cadillac Ciel concept

The Cadillac Ciel concept, a four-seat convertible, has just been revealed at the 2011 Pebble Beach Concours d’Elegance. "The Ciel is about the romance of the drive," says Clay Dean, global design director of Cadillac. "It emulates the great touring cars seen on the greens at Pebble Beach, but with a modern flair that projects Cadillac's vision for the future." Interior design manager Gael Buzyn says, "Simplicity and lightness ensure nothing distracts from the open driving experience, while the color and materials lend the feeling that the vehicle's environment blends with the surroundings." The four-door Cadillac Ciel concept was developed with a long, low proportion, reminiscent of classic automobiles, while the interior features Italian olive wood, machined aluminum and hand-tipped leather.
