The Cadillac Ciel is a hybrid electric concept car created by Cadillac and unveiled at the 2011 Pebble Beach Concours d'Elegance. The Ciel has a twin-turbocharged 3.6-liter direct injection V6 producing 425 hp[1] and a hybrid system using lithium-ion battery technology.[2][3] The Ciel is a four-seat convertible with a wheelbase of 125 in. It was developed at GM Design's North Hollywood Design Center.[4]
The Ciel has rear suicide doors, and the interior features a smooth wooden dashboard with a simple gauge look. The word "Ciel" is French for "sky"- which is what the designers had in mind when they made the vehicle.
In 2012 and early 2013, Cadillac contemplated developing a production car based on the Ciel. However, in July 2013, they decided not to pursue the venture.[5]
