Hamilton was fastest in the third practice session of Belgium at Spa. The brit were half a second faster than the closest car, fellow Mercedes driver Nico Rosberg. Both drove with full fuel load and prime tyres. Third and fourth respectively were both Ferrari drivers Vettel and Räikkönen.
Red Bull showed a decent pace this session, with Both Ricciardo and Kvyat leading for a while, both with the softer tyre option on. Force India, too, showed great performance, with Perez in 5th before both Red Bull drivers, and Hulkenberg right behind them. Williams completed the top ten with 9th for Bottas and 10th for Massa.
