Tatiana Calderon has been promoted to Sauber's test driver for the upcoming Formula One season.
Calderon spent the 2017 season as the team's development driver alongside her GP3 Series commitments. Her new role will involve further work in the simulator and engagement with the engineers during F1 race weekends and back at the factory in Hinwil.
The Colombian finished 18th in the GP3 drivers' standings, finishing in the points on two occasions. She will participate in a third GP3 season, moving from DAMS to Jenzer Motorsport for the upcoming campaign.
"I am very pleased to confirm my role as Test Driver for the Alfa Romeo Sauber F1 Team in the 2018 season,'' said Calderon.
