This is a brutal race, on a bumpy track, with walls to catch the unwary, in 30C heat and 70% humidity, which runs close - and sometimes up to - the two-hour time limit. No rain is predicted.
The teams will all try to one-stop. Last year, there was a very a slow start to the race, with the leaders managing tyre life, before building speed as the pit-stop window nears. But this year the softest tyre is more durable, so the need for management might not be as high.
For the leader, extending the first stint is key, because there has been a safety car in every race so far, so you want to minimise the risk of having stopped before it comes out, because stopping under the safety car saves 11 seconds of race time, and therefore provides a huge advantage over a car stopping under green-flag conditions. At the same time, the power of the under-cut - stopping first and gaining a position through speed on fresh tyres - is high. So it’s a trade-off.
In terms of the safety car, in Singapore teams generally have two laps to decide whether to stop, because although stopping on the first lap is theoretically slightly quicker, you can gain by doing it on the second because you keep track position and your pit stop time might be slightly faster owing to the less-crowded pit lane.
