May 11 (GMM) New Zealand youngster Brendon Hartley on Sunday revealed that he is Toro Rosso's unofficial test driver.



The 18-year-old recently gave the Faenza based formula one team's 2008 car, the STR3, its shakedown track debut in Italy, and he has also appeared for the Red Bull-sponsored teams in demonstration runs and for a quick test at Silverstone.



Hartley is currently racing with Red Bull backing in British F3.



"It seems a bit strange to say that but I am their test driver," Hartley is quoted as saying by New Zealand's Herald on Sunday.



"I'm not the official test driver but I'm the man who does all their aero testing and stuff," he added.
