Behind Hamilton, Sergio Perez put in a strong effort, ending the session P5 for Force India, but the man right behind the Mexican was anything but happy with his performance.
Valtteri Bottas appeared troubled throughout the initial session, complaining of his Mercedes W08's unstable rear end which he labeled as "undriveable".
Kimi Raikkonen was 1.2s off the fastest time, just beating Fernando Alonso to P7. The McLaren man put in a mighty lap but still struggled with power unit issues during the 90-minute session.
