Porsche, which revolutionised open-air driving with the original 1967 911 Targa, is now offering owners of its Cayenne SUV a newly developed, optional Panorama roof system featuring a surface area approximately four times larger than the Cayenne's optional tilt-and-slide sunroof.

The new roof system has three movable segments and one fixed segment, all made of laminated safety glass. By operating the system with an illuminated rotary switch in the Cayenne's roof console, users can open the roof above the front seats, above the rear seats, or above all seats.

The Panorama roof will be available in December 2004 as a model year 2005 option on all Cayenne models for a US price of $3,900.
