FRANKFURT -- Porsche aims to introduce a large wagon as a fourth model line, a business magazine said on Thursday.
Manager magazine said the four-door car, named "Tourer", could be marketed in 2008 and would be almost as large as its Cayenne sport-utility vehicle.
Porsche Chief Executive Wendelin Wiedeking will decide on the car in July and then seek approval from the supervisory board, the magazine said in a preview of its May 27 edition.
A Porsche spokesman said the report was pure speculation, reiterating that a decision on a fourth model line will be taken in the summer.
A task force was mulling whether a new line should be built alone or in cooperation with a partner, he added.
"The most economical solution will be implemented if there is a fourth model line," he said.
Porsche has been mulling whether to introduce a fourth model line in addition to the Boxter roadster, Cayenne and 911 premium sports car for a while.
The firm has said it will detail plans eventually to build a hybrid version of its Cayenne model.
