Iconic American luxury auto brand Cadillac unveiled its new hybrid concept, described as an “expression of Cadillac’s historical grandeur.” The Ciel concept, which will be on show at the Pebble Beach Concours d’Elegance, is a four-seat convertible powered by a 3.6-liter V-6 engine, paired with hybrid drive. Designed to fit in with the touring carson display at Pebble Beach, the model is “about the romance of the drive,” says Cadillac-owner General Motors, featuring generous room for two couples across two rows. Complete with rear-hinged rear doors, the Ciel concept is clearly trying to evoke a sense of the freedom and history of motoring through the great outdoors, with a polished aluminium windshield frame and vertical lights. Inside, the passenger space is characterized by Italian olive wood, machined aluminium and hand-tipped leather designed to add to the romance, with interior design manager Gael Buzyn likening the design to a “vintage wooden boat.” Luxury touches include a small humidor for holding cigars and an in-built cashmere blanket which appears at the pull of a tag to cover up the rear seat passengers, should they get chilly. The concept is among several new models on show at this week’s Pebble Beach Concours d’Elegance, including models from Infiniti and Lexus.
