Toro Rosso, announced its second driver for 2015, which is Carlos Sainz Jr. The son of the twice champion of WRC (1990 and 1992), Carlos Sainz, is 20 years old, so he will constitute together with Verstappen the youngest driver duo in Formula 1.
It is definitely a risk for a group to have two emerging drivers, but the Toro Rosso has accustomed us to giving a chance to younger talents.
Carlos Sainz Jr said:
I am really very happy to be driving for Toro Rosso. Since becoming part of the Young Driver Programme of Red Bull, was my goal and I want to thank Red Bull for the confidence they showed me. I had a very successful season in the World Series with Renault this year, and now I look forward to make the next step in Formula 1.
