The Toro Rosso team will use its 2014 race drivers Jean-Eric Vergne and Daniil Kvyat in the upcoming Formula 1 tyre test in Bahrain.
Pirelli was given dispensation to run a three-day test at the Sakhir circuit, and Red Bull, Ferrari, Toro Rosso and Mercedes will be in action.
Toro Rosso said Vergne will drive on the first day and a half, before Russian Kvyat takes over for the remainder of the test. They will be using this year's STR8 car.
The test will run from December 17-19.
GP3 champion Kvyat will make his grand prix debut next year, replacing Red Bull-bound Daniel Ricciardo alongside Vergne.
