The
Cadillac Ciel Concept first arrived at the 2011
Pebble Beach Concours d'Elegance amidst great acclaim and plenty of fanfare, as show-goers gawked at the big convertible and its impressive 425-horsepower twin-turbocharged V6 engine complemented with a hybrid lithium-ion battery system. Though the American automaker didn't have a brand-new model for this year's edition of the classic California event, they did release a pair of renderings that show off a possible coupe version of the Ciel.
