Jaguar F-type prototype (2013): the testing videos

As Jaguar confirmed its new F-type sports car at the 2012 New York auto show, it issued some teaser video footage of the new £55,000 roadster landing in showrooms in spring 2013. Jag ambassador and former racer Martin Brundle hitches a lift with the company's chief dynamics engineer Mike Cross for a few hot laps in the F-type prototype around its handling circuit at Gaydon. We can safely ignore the hyperbole poring forth ('It's responsive, it's a great car to drive') but it's a good chance to see the all-aluminium F-type in action.

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.
