The car was revealed to be a Red Bull RB5 with a 2008-spec Ferrari 056 engine in Barcelona on March 9, 2009. It was revealed before the testing session.

The Toro Rosso STR4 was the last-ever Toro Rosso car to be built by its senior sister team Red Bull Racing, as from the 2010 season onwards Toro Rosso switched to in-house designed cars.

Competition history

The STR4 was driven by Sébastien Bourdais and Sébastien Buemi for the first half of the season. Jaime Alguersuari replaced Bourdais from the Hungarian Grand Prix onwards.

Sébastien Buemi

Buemi scored 7th place on his debut race at the 2009 Australian Grand Prix. His teammate Sebastian Bourdais also scored points that race. He went on to finish 8th in China, before finishing 7th and 8th in the final two races in Brazil and Abu Dhabi.

Sébastien Bourdais

Bourdais scored an 8th place at the 2009 Australian Grand Prix. His teammate Sébastien Buemi also scored points that race. However Bourdais had poor results during the 2008 season, scoring only 4 points unlike his 2008 teammate Sebastian Vettel who scored 35 and a race win in Monza. At the 2009 Hungarian Grand Prix, he was replaced by Jaime Alguersuari following a similar season of poor results, having scored only 2 points after the German Grand Prix before he was fired.

Jaime Alguersuari

Alguersuari made his debut at the Hungarian Grand Prix as his predecessor Sébastien Bourdais was replaced following a string of poor results. However he only managed to finish 3 races out of the 8 he raced in, with a best result of 14th in the Brazilian Grand Prix.

Sponsorship and livery

The STR4's base colour was dark blue, thanks to its main sponsor, Red Bull. The energy drink manufacturer's logo and lettering added red accents to the car.

At the Chinese Grand Prix, as a tribute to the victims of the 2009 L'Aquila earthquake collapse, Toro Rosso included a decal with the words "Vicini All'Abruzzo." for the race weekend on their cars.
