The team will field an all-rookie driver line-up this season, with 17-year-old Max Verstappen being joined by Carlos Sainz Jr, with Daniil Kvyat moving up to Red Bull and Jean-Eric Vergne having been replaced.
Toro Rosso becomes the seventh team to unveil its 2015 car, with Force India only having launched its new livery and the Red Bull RB11 set to roll out at Jerez on Sunday.
