Zuber joins iSport

Zuber, 23, had a test with the team last year and has driven for the team on a number of occasions during the past month – setting the quickest time on his maiden outing with them at Paul Ricard in France.

And the Austrian driver is expecting to push for the title next season, right from the start of the season.

"Since I tested with iSport at the end of 2005 I have had a good relationship with the team and after the recent tests I was confident that this would be a good option for me.

"I have made some good friends in the team already and I am looking forward to working with them, I am sure we can push for the Championship. I can't wait for the Valencia test [in January] and getting into a serious programme."

Zuber made his GP2 debut with Trident Racing this season and took his first win in Istanbul on his way to 14th in the championship."
