Jaguar C-X75 concept

We waited with baited breath to see what the Jaguar design team had in store at the Paris motor show this year, and we weren't disappointed with the resulting showcar. Created by a team led by Matthew Beaven, Principal Designer at Jaguar Advanced Design, the C-X75 is both a celebration of Jaguar's 75 year history and a design showcase for the company's hybrid turbine technology. Read more about our opinion of the design in our 2010 Paris Motor Show Highlights and see the extensive compilation of images – including sketches and studio shots – in the photo gallery below.

Cadillac Ciel concept

The Cadillac Ciel concept, a four-seat convertible, has just been revealed at the 2011 Pebble Beach Concours d’Elegance. "The Ciel is about the romance of the drive," says Clay Dean, global design director of Cadillac. "It emulates the great touring cars seen on the greens at Pebble Beach, but with a modern flair that projects Cadillac's vision for the future." Interior design manager Gael Buzyn says, "Simplicity and lightness ensure nothing distracts from the open driving experience, while the color and materials lend the feeling that the vehicle's environment blends with the surroundings." The four-door Cadillac Ciel concept was developed with a long, low proportion, reminiscent of classic automobiles, while the interior features Italian olive wood, machined aluminum and hand-tipped leather.
