Sauber confirm Esteban Gutierrez for 2013

Sauber have revealed that Esteban Gutierrez will be their second driver for the 2013 campaign.

The 21-year-old has been test driving for the Swiss outfit this season and will form a new-look partnership alongside Nico Hulkenberg.

Neither of Sauber's current drivers will be with the team next year, with Kamui Kobayashi's contract expiring and Sergio Perez joining McLaren as a replacement for Lewis Hamilton.

Hulkenberg is leaving Force India this winter and will be the senior driver to new recruit Gutierrez in 2013.
