As Thursday’s FP1 concluded, Lewis Hamilton dominated the session on his Ultra Soft compound tyres, with his teammate Nico Rosberg following closely behind him.
Throughout the entire opening practice session for the Monaco GP, Rosberg and Hamilton traded that P1 spot but the Brit held on firmly to put an unbeatable time of 1:15.537.
Rosberg, who is also the Championship leader, suffered a left rear puncture and had to nurse his Silver Arrow back to his garage.
Ferrari’s Sebastian Vettel was third quickest ahead of Daniel Ricciardo, who was running Renault’s upgraded engine, and his Red Bull team-mate Max Verstappen.
While the Ultra compound dominated the talk of the first practice session, in typical Monte Carlo style, there was plenty of drama at the Circuit de Monaco.
Williams driver Felipe Massa continued his bad luck of slamming into the barrier at Turn 1 with his front left wheel taking most of the hit. His practice was ultimately cut short.
Toro Rosso duo Carlos Sainz and Daniil Kvyat also caused scares during the session with both of them causing yellow flags to wave after locking up a few time on the track.
There was an engine issue for Haas’ Esteban Gutierrez while Rosberg’s late puncture resulted in an issue for McLaren driver Jenson Button.
He went through the same turn shortly after the Mercedes driver and apparently hit a loose drain cover, causing the session to be red flagged with 4 minutes left on the clock.
Adding to Button’s disappointment, himself and his teammate Fernando Alonso couldn’t get the pace they wanted with the Ultra soft compound, which is a worry if they are to mount any serious challenge during the qualifying sessions.
