The longest race on the calendar will be shortened with faster lap times, as the Singapore Grand Prix circuit receives upgrades between 2023 till 2026.
On average the Singapore Grand Prix takes two hours to complete, as the drivers race through 23 corners for 61 laps.
But redevelopments to 'The Float' at Marina Bay between Turns 16 and 19 mean that the revised temporary circuit layout will be reduced to 4.928km from 5.063km, and the number of laps increased to 63.
This means the minimum race time is now expected to be 01:30:34, which is 30 minutes shorter than the usual time it takes to complete.
Turns 16 and 19 is the place where Nelson Piquet Jr infamously crashed deliberately in 2008, after being ordered by the team to influence the race result and enable his team mate Fernando Alonso to win.
Lap times to be nearly eight seconds quicker
"Simulations based on a 2020 Formula 1 car indicate the best qualifying lap time at approximately 01:27.7," says the Singapore Grand Prix.
The fastest lap during this years Grand Prix was 1:46.458 set by George Russell, which means the predicted times are set to be nearly 20 seconds quicker.
These corners will now be re-aligned into a 397.9m long straight, bringing the total number of turns to 19.
