Original: In the autumn of 2005, Red Bull announced that they had purchased the Minardi Formula One team, and it would be known as Scuderia Toro Rosso (Italian for Team Red Bull) from 2006 onwards. Scuderia Toro Rosso (STR) operates as a separate team, but the two share certain technical resources.
Simplified: Red Bull also own another F1 team: Scuderia Toro Rosso.
