Nakajima has been with Williams since 2006

Kazuki Nakajima, of the Grove-based Williams team, expects a tough test at the Canadian F1 Grand Prix.

Nakajima, who is competing in his first full season after being promoted from the team's test driver, admits he is unfamiliar with the Montreal track.

"It's my first full weekend of racing there," said Nakajima. "The circuit is very challenging with its walls and high kerbs.

"It is not an easy track but it should be fun to drive." he added.
