Cadillac has unveiled the Ciel concept at the 2011 Pebble Beach Concours d'Elegance.
The Ciel is a four-seat convertible with a short, polished aluminum windshield. Power comes from a twin-turbo 3.6-liter V6 engine with 425 hp (317 kW / 431 PS) and 583 Nm of torque.
Inspired by the natural beauty of the California coast, the Ciel Concept features an interior finish in Italian Olive wood, rides on brushed nickel-plate and milled-billet aluminum wheels 22 inches in size.
