Mercedes replace electronics in Hamilton's car

Lewis Hamilton will drive in qualifying with a new energy store. This is his first energy store change of the season, with each driver allowed two changes. Toro Rosso are already in the position for penalties as a result of changing this part too many times. Valtteri Bottas, the other silver arrows driver, managed to close the gap between Mercedes and the other two big teams. Meanwhile, in this mornings session, Hamilton remained off the pace.
