Scuderia Toro Rosso have confirmed they will run three of the main contenders for their two available 2009 race seats in next week's Barcelona test.
Red Bull protege Sebastien Buemi, 2008 race driver Sebastien Bourdais and former Honda and Super Aguri racer Takuma Sato will all have seat time during the test as the team evaluate their possible 2009 driver line-up.
Both Sato and Bourdais will have a day-and-a-half in the car, with Buemi available on all three days of the one-car test. Sato will run on Monday and Tuesday, with Bourdais on duty Tuesday afternoon and Wednesday.
There had been discussions regarding the possibility of GP2 champion Giorgio Pantano having a run, but the team have confirmed he will not be in the car.
Toro Rosso currently have no confirmed drivers for next season following Sebastian Vettel's promotion to Red Bull Racing. In addition to the trio who will test at Barcelona, GP2 runner-up Bruno Senna is also a contender for the drive, but will be trying out for Honda at Barcelona.
Honda's Rubens Barrichello has also had discussions with the team and is an outside contender for the drive, but autosport.com understands he has been asked to bring sponsorship money.
