Reigning Formula One champion Lewis Hamilton completed his first laps of a Formula One car since February on Tuesday at a private Mercedes test at UK circuit Silverstone.
Mercedes booked a two-day test to gain an experience of the safety procedures for the behind-closed-doors races which will start the 2020 season in July. The season will start with the Austrian Grand Prix on July 5.
After Valtteri Bottas drove the 2018 car on Tuesday, Hamilton took over on Wednesday. F1 teams are entitled to two filming days per season, in old machinery, and each limited to 100km -- equating to around 17 laps of the Silverstone circuit.
