The Toro Rosso STR2 is the car with which the Scuderia Toro Rosso team competed in the 2007 Formula One season. It was unveiled on 13 February 2007 at the Circuit de Catalunya. The car is, controversially, a variant of the Red Bull RB3 chassis. It was initially driven by Vitantonio Liuzzi and Scott Speed, until Speed was replaced by Sebastian Vettel at the Hungaroring for the remainder of the season. The car in a modified form was also used to compete in the first five races of the 2008 Formula One season. The modified car was driven by Sébastien Bourdais, four-consecutive-time Champ Car winner, and Vettel. The STR2 was the first-ever Toro Rosso F1 car to use the mandatory 90-degree Formula One V8 engine configuration but Toro Rosso opted for the 2006-spec Ferrari 056 instead of the 2007-spec because of 1-year old Toro Rosso engine policy and as a cost-saving measure.

Scuderia Toro Rosso, commonly known as Toro Rosso or by its abbreviation STR, was an Italian Formula One constructor. It was one of two Formula One constructors owned by Austrian conglomerate company Red Bull, the other being Red Bull Racing. Toro Rosso functioned as a junior team to Red Bull Racing, with the aim of developing the skills of promising drivers for the senior team. The constructor made its racing début in the 2006 season, moving to complete independence from its sister team in 2010. The team changed its name to Scuderia AlphaTauri in 2020 to promote parent company Red Bull's fashion label of the same name.
