Barcelona - Toro Rosso will become the final Formula One team to reveal its car for the 2009 season when it launches the STR4 in Barcelona on Monday.

The team said Wednesday will test on the Circuit de Catalunya next week before the season gets underway on March 29 in Melbourne.

Drivers Sebastien Bourdais and Sebastien Buemi will present the car. The team clinched its first race victory in 2008 when Sebastian Vettel won the Italian Grand Prix. The German has now switched to sister team Red Bull. (dpa)
