Strategy

The race was not obvious in terms of pit stop strategy, with different teams and different drivers choosing to make anywhere from 1 to 3 stops.

The race winner, Nico Rosberg, was on a 1 stop strategy.

Excluding those drivers who could not finish the race, those on a 1 stop strategy didn't gain or lose any positions on average, the ones on a 2 stops strategy lost an average of 0.86 positions, while those on a 3 stops strategy lost an average of 0.5 positions.

This difference in possitions gained, together with a deeper nalaysis of each strategy, reinforces the conclusion that a 2 stops strategy was the best option, even if Nico Rosberg managed to win the race making 1 stop.

It is important to note that this might not always be the case for other races held at the Circuit de Monaco, as the conditions might change from year to year, in terms of wheel degradation, accidents, safety cars, etc.

Incidents

There race went on mostly with no incidents. Only 3 divers were involved in circumstances that were severe enough to prevented them from finishing the race.

These included, Max Verstappen, who had to retire due to an accident on lap 62, Fernando Alonso, who experienced issues with the gearbox on lap 41, and Pastor Maldonado, who saw the breaks of the car give up on lap 5.

As the qualifying session went on, with the track rubbering in, and the drivers testing the limits of the grip of their cars, the times per lap dropped, and 14 out of the 15 drivers that took place in Q2 were able to improve their times.

The Q3 is the time were all the remaining drivers put all their cards on the table, even those with a superior car who might have been managing their times in Q1 and Q2 push their cars to the limit in Q3. It therefore comes as no surprise that 7 out of the 10 drivers that took place in Q3 were able to improve their times.
