THE Grove-based WilliamsF1team have named Japanese driver Kazuki Nakajima, 21, as a team test driver.

Nakajima, who is racing in the Formula 3 Euro Series with Manor Motorsport, will take up his place as an official test driver after he finishes his race season.

WilliamsF1 Team Principal, Sir Frank Williams, said: "Kazuki has consistently demonstrated his potential through karting and other junior formulae. Having assessed both his potential in the car and his aptitude out of it, we believe he has the necessary ingredients to graduate to Formula One in a testing role."

He will work alongside Narain Karthikeyan and race drivers Nico Rosberg and Alex Wurz on the winter development of the Toyota-powered WilliamsF1 FW29 in readiness for the 2007 Formula One World Championship.

Nakajima is the son of Formula One driver Satoru Nakajima, who raced for Lotus and Tyrrell in the mid-1980s and early 1990s.
