Wendelin Wiedeking, chairman of Porsche, says the decision will be made next year. It is unclear whether Porsche will make the vehicle without a partner.
But Porsche has room to build it at the Leipzig, Germany, factory where the Cayenne SUV is made.
Wiedeking was interviewed at the Paris auto show by Automotive News Europe's Executive Editor Peter Brown and reporters Jens Meiners and Diana T. Kurylko.
What percentage of components do the Boxster and 911 share?
It is in the same region as the last models, about 36 or 37 percent.
Will you expand the Boxster range? We've heard about a coupe.
We will do further products based on the existing product line and body. There will be no new products priced below the Boxster.
Dealers want the fourth car sooner rather than later. When will you decide on a product?
Next year. When we make the decision, we will have fewer friends in the industry and more competitors.
Does the new car have to be manufactured on a rear-wheel-drive platform?
We want to share, especially in the future, more systems and components within the product range. That means engines and electronics systems. That is a must.
Do you have room in Germany to build another vehicle?
The production decision is the last one you make. You have to know what concept segment, what kind of customers and what price. There is huge space in Leipzig and if we [do it], we want do it there.
Even this is not decided yet. We can do it ourselves. But there is always a question of strategy and whether it makes sense to do it with a third party.
