Excerpt:
BBC F1 chief analyst Eddie Jordan
"The Volkswagen Audi Group is the second biggest car maker in the world and as such it needs to be in Formula 1. But it will not enter it while the sport remains under the control of Bernie Ecclestone, who VAG boss Ferdinand Piech dislikes on a personal and professional basis. Martin Winterkorn - the chairman of the board of management of Volkswagen - is being groomed as Piech's successor and he has always believed that F1 is a great platform for the group's brands. I am told he privately believes VAG should be a part of F1. If VAG did come to F1, I believe it would be with their own team, with the car designed and made in Germany."
