Lewis Hamilton aims to turn up the heat in his bid for a sixth Formula One championship at this weekend's Singapore Grand Prix.
The Mercedes driver heads into Sunday's race with a 63-point lead over teammate Valtteri Bottas.
As with last year's race, drivers can expect sweltering heat and humidity. In addition to the heat, a thick haze has set in over the city-state with advisories issued from the national government over "unhealthy" air conditions.
Hamilton will be hoping for a repeat of the 2018 race here when he won comfortably from pole position to extend his championship lead.
He was on a major roll entering last year's GP, having won four of the past five races. While he already has eight wins this season, the British driver last won at the Hungarian GP in early August.
"The offset schedule and the climate make it a demanding weekend for the team," Mercedes team principal Toto Wolff said of the night race.
"Temperatures in the garage can easily reach 40 degrees Celsius (104 F) or more with high humidity levels as well. It's a tough environment to work in and it's equally challenging for the drivers and the car itself."
"After two positive weekends in Belgium and Italy, the race in Singapore doesn't look as good on paper for us, because of the very different circuit layout, featuring lots of slow corners and fewer straights ... but we will give our all to have a good result."
