Jaguar has revealed the C-X17 SUV concept on the eve of the 2013 Frankfurt Motor Show.

Volkswagen Iroc concept

The Iroc is a show car preview of a production coupe to be launched next year that will fill a gap in the Volkswagen model line up left by the demise of the Corrado 11 years ago. Volkswagen describe the Iroc as "transferring the globally successful Scirocco idea into the future" - the Scirocco Mk1 by Giugiaro being produced from 1974-1982, the Mk2 from 1982-1992. Like the Scirocco, the Iroc is a front wheel drive coupe with four seats - as opposed to the 2+2 seating arrangement of the only other sports coupe from Volkswagen Group: the Audi TT.
