Stoffel Vandoorne will return to the McLaren-Honda MP4-31 that he took to a tenth place finish at the Bahrain Grand Prix during the post-Spanish Grand Prix test at the Circuit de Catalunya next week.
The Belgian rising star and 2015 GP2 Series champion will participate in the second day of the two-day test with the team, with regular race driver and his Bahrain team-mate Jenson Button running on the first day.
The same day Vandoorne tests for McLaren, 2015 GP3 Series Champion Esteban Ocon will have his first taste of Mercedes machinery, running with the multiple-championship winning outfit a day after current championship leader Nico Rosberg.
It will be Ocon’s second day at the test, with the Frenchman having already been confirmed to run with the Renault Sport F1 team on the opening day before handing over to Kevin Magnussen.
Sahara Force India have confirmed that their 2016 reserve driver Alfonso Celis Jr will take part on both days of the test, while the Haas F1 Team will run both of their race drivers, Romain Grosjean on Tuesday and Esteban Gutierrez on Wednesday.
Alex Lynn and Felipe Massa have already been confirmed to run with Williams Martini Racing, but Scuderia Ferrari, Red Bull Racing, Scuderia Toro Rosso and the Manor Racing squads have yet to announce their plans.
The Sauber F1 Team have already decided to skip the test due to not having any upgrades to test nor having a young or test driver to run.
