JAPANESE driver Sakon Yamamoto will take on the position of second test driver with the Leafield-based Super Aguri F1 team in 2007.

The 24-year-old made an encouraging F1 debut during the four months he drove for the team in the latter half of the 2006 season.

In his new role he will be supporting SAF1 Team race drivers Takuma Sato and Anthony Davidson, in addition to newly-appointed test and reserve driver Giedo van der Garde.

Yamamoto said: "It is great news that I am able to stay in Formula One with the Super Aguri F1 Team in 2007 and would like to thank everyone who has supported me, especially Aguri-san. I will try to do my best in my new role and give the team good support from my time in the car next year."

Team principal Aguri Suzuki said: "I am very happy that Sakon will remain a member of the team next season. We will help him to secure a race seat in another category for 2007 and I am confident that his experience gained from Formula One racing this year will help him achieve this goal."
