The Toro Rosso STR6 is a Formula One racing car developed by Scuderia Toro Rosso for the 2011 Formula One season. It is the second car that the team has built entirely on their own following the introduction of regulations that banned the use of "customer chassis", a chassis developed by one team and purchased by another (prior to 2010 Toro Rosso used a customer chassis from its "big brother" Red Bull Racing). Toro Rosso STR6 was also the first-ever Faenza-based Formula One car to utilize Pirelli tyres since 1990 Minardi M190.
