Pebble Beach, California – Cadillac has unveiled the Ciel concept, an open-air four-door grand touring car, at the Concours d’Elegance show at Pebble Beach.

Pronounced “C-L,” the French translation for “sky,” the concept is a four-seat convertible that the company said is a new expression of Cadillac’s historical grandeur, as well as a celebration of open-air motoring.

“Large, expressive luxury is innate to Cadillac and the Ciel recalls that heritage while suggesting where the brand can go in the future,” said Clay Dean, global design director for Cadillac. “Authentic luxury is driven by experiences, not just products, and Ciel is about the experience of the journey.”

The Ciel uses a twin-turbocharged 3.6-litre direct-injection V6 engine paired with a hybrid system that uses lithium-ion battery technology. It was developed at GM Design’s North Hollywood Design Center.
