In no real surprise as only three race drivers tested today at Silverstone, McLaren Honda’s Fernando Alonso topped the timesheets in the first of the two-day in-season test.
Alonso’s best time of 1:31.290 was set in the morning session before rains fell in the afternoon. The only other race drivers that ran were Toro Rosso’s Carlos Sainz Jr. and Manor’s Rio Haryanto, who only clocked best times of 1:34.643 and 1:35.631, respectively.
Alonso was also one of the two busiest drivers on the day, completing 105 laps. That was second only to Mercedes junior driver and Renault reserve driver Esteban Ocon, who in his first day in the Mercedes W07 chassis banked 123 laps. Ocon’s best time was a 1:32.833.
Ocon was tops among the young drivers who tested, with the others Alex Lynn (Williams), Charles Leclerc (Ferrari), F1 test debutantes Nikita Mazepin (Force India) and Santino Ferrucci (Haas), Sergey Sirotkin (Renault) and Pierre Gasly (Red Bull). Gasly did not clock a representative time as he ran primarily in wet conditions.
Pascal Wehrlein also ran a 2014-spec Mercedes to continue testing of Pirelli’s new 2017 tires.
