George Russell and Nicholas Latifi tested for Mercedes at the Algarve International Circuit in Portugal last weekend.
The pair drove a 2015-specification Mercedes W06. Mercedes confirmed the purpose of the test was to evaluate the two young drivers.
Russell, 19, joined Mercedes’ young driver programme in February. He will race for ART in the GP3 championship which begins at the Circuit de Catalunya next month.
Latifi will start his second full season in Formula Two (previously GP2) this year. The 21-year-old was Renault’s test driver last season but has since left the team.
