Having reached the point where he is no longer eligible to take part in the 'rookie' session at each A1 Grand Prix round, Nico Hulkenberg will rely on feedback from Formula BMW world champion Christian Vietoris as he seeks to keep Team Germany at the head of the points table.

Willi Weber's team, run by British-based Super Nova, leads the standings by twelve points after the opening five rounds of the season, but the German has admitted that there were several reasons for bringing in a second driver.

"Nico has driven a faultless season to this point, and has demonstrated what he can do by scoring two wins," Weber said, "However, there are three reasons why we aim to provide the best possible support for him. Firstly, because of his depth of experience, the regulations prohibit his participation in the rookie session on Friday - Christian will now assume this role. Secondly, a reserve driver is now always on hand just in case of emergency, and, thirdly, Nico will have a busy racing schedule during the 2007 season, so, it is possible that Christian will also race."

Still only 17, Vietoris will get his first taste of the A1GP series this weekend in New Zealand, where the championship restarts after its Christmas break. It will be his first outing of any kind since winning the FBMW World Cup in Valencia at the end of the 2006 season, having already become successor to Hulkenberg as German champion.
