Williams, Toro Rosso and McLaren have opted for similar splits. At the former, Valtteri Bottas will be joined by reserve driver Alex Lynn, while McLaren’s reserve Stoffel Vandoorne will be in action alongside Fernando Alonso. Brazilian racer Sergio Sette Camara, meanwhile, will drive an F1 car for the first time, after landing a call up to test for Toro Rosso alongside Carlos Sainz. Haas‘s American development driver Santino Ferrucci will also get his first taste of F1 machinery, as will his Russian counterpart at Force India, Nikita Mazepin, with both men set to test on both days.
Alongside their normal duties – which will be led by Esteban Ocon – Mercedes will run a 2014-spec car, with Pascal Wehrlein at the wheel, dedicated solely to working for Pirelli as F1’s official tyre supplier concentrates on developing their 2017 tyres. All data from the car will be shared openly with the other teams.
