Singapore is always one of the most exciting and unpredictable races of the year, in which pit stop strategy often plays a crucial role in the outcome: also because of the near certainty of a safety car at some point during the arduous two hours. Having said that, pole position has historically had a strong influence on the race win at Marina Bay, soqualifying will be crucial as well. In order to prepare, teams will have to pay particularly close attention to the free practice data as track temperature at night will evolve in quite a different way than it does at a conventional daytime race. Understanding this will be key to getting a good handle on wear and degradation rates, and so implementing an effective tyre strategy.
