Helmut Marko
The final season of F3000, 2004, was dominated by Arden's lead driver Vitantonio Liuzzi; the support of Robert Doornbos helped to secure both the Drivers' and Constructors' Championship titles by a large margin. The team won eight of the ten championship rounds that year, with Liuzzi taking seven and Doornbos winning one. Liuzzi was brought to the team by his manager, Helmut Marko, with sponsorship from Red Bull. At this time Horner based his Arden International Team at Prodrive premises in Banbury, before relocating them to the former 22 Motorsport facility close by.
