With Vettel moving to Red Bull Racing replacing the retired David Coulthard, Sébastien Buemi and Sébastien Bourdais led the team's assault in the 2009 World Championship. After the previous year's success, several drivers wanted to drive for Toro Rosso, including Takuma Sato (who even did three tests with the team) and Bruno Senna. Toro Rosso unveiled their new car last of all the teams taking part in the 2009 season, on 9 March 2009. Before the season started, the team's boss Franz Tost said that it would be "difficult" to do as well as they did in the season. On 16 July 2009, the team announced that Sébastien Bourdais' contract was to be terminated with immediate effect due to disappointing results. On 20 July 2009, the team announced that Jaime Alguersuari would replace him as official driver for the rest of the season. Multiple WRC Champion Sébastien Loeb had been quoted in the French sports-paper L'Equipe as being interested in replacing Bourdais. It had been stated that Loeb would not be available to race in F1 until after the end of the WRC season. He would've been available to make his F1 début at the 2009 Abu Dhabi Grand Prix in November. However, this was not to be as the FIA denied him a super licence which is required to drive in Formula One. The season ended with Toro Rosso finishing in tenth and last place in the championship after being overtaken by Force India after their podium finish in Belgium. However, Toro Rosso's form picked up towards the end of the season with Sébastien Buemi scoring points in the final two races. However, Jaime Alguersuari failed to score any points in the season.
