Sauber has confirmed the signing of Colombian Tatiana Calderon to the role of development driver.
Caldero will join the team for an "extensive" programme including professional simulator training sessions and coaching with the team's engineers in Hinwill and during some grand prix weekends. The 23-year-old moved to Europe in 2012 and finished second in the MRF Challenge Formula 2000 in 2015-16, competing in last year's GP3 championship -- though she recorded just two top-ten finishes.
Calderon will compete in GP3 again this season alongside her new role as development driver for Saber.
Sauber boss Monisha Kaltenborn said: "We are very pleased to welcome Tatiana onboard to the Sauber family. We have the opportunities and facilities to provide Tatiana a professional platform on which she can further develop her knowledge and skills in racing. I am convinced that we can provide her lots of in-depth motorsport know-how for her future career in racing."
Calderon hopes the role is the next step towards a full-time F1 drive.
"I am extremely happy to join the Sauber F1 Team as a development driver. I want to thank Monisha Kaltenborn and the whole team for giving me this opportunity, and also Escuderia Telmex for their support. I am grateful to be working with such an established Formula 1 team and to benefit from its long experience. I look forward to working with the team and learning as much as I can. It is a step closer to my dream - one day competing in Formula One."
