It was Scuderia Toro Rosso's turn to tease the birth of its 2017 challenger, the STR12, in a video posted to the team's Twitter account.

Members of the junior bull outfit frantically leave their desks to head to the workshop to witness their car come to life.

Following a year-long  partnership with Ferrari, Toro Rosso has switched back to Renault power for 2017, a change which will hopefully enable the Faenza-based outfit to take its game to the next level as it seeks to challenge main rivals Force India and Williams.
