F1 title permutations: How Lando Norris, Max Verstappen and Oscar Piastri can win it at Abu Dhabi GP - ESPN

Lando Norris, Max Verstappen and Oscar Piastri are set for an epic Formula 1 title decider on Sunday, with Verstappen on pole for the Abu Dhabi Grand Prix.

Verstappen, after taking advantage of a questionable strategy call from McLaren in win in Qatar, qualified ahead of Norris and Piastri at Yas Marina on Saturday.

It means the title race is heading to a nailbaiting finale at Yas Marina, with three drivers having a shot at claiming the championship for the first time since 2010.

Norris remains the favourite, although what had looked like a comfortable 30-point lead over Piastri and a 42-point lead over Verstappen pre-double DQ in Las Vegas has been whittled down.

Following a disappointing weekend for Norris in Qatar — with Piastri winning the sprint race and Verstappen the main event — Norris is 12 points ahead of Verstappen, and 16 ahead of his teammate Piastri.

Here's how all three stack up heading into the season-ender.

Norris — 408 points

Verstappen — 396 points

Piastri — 392 points

There are 25 points up for grabs in Abu Dhabi ...

Before we explain what happens if drivers are level on points, lets get the basics thrashed out.

Norris will win his maiden world championship if Verstappen doesn't outscore him by 13 points, and Piastri by 17.

As there are 25 points available for a win, 18 for second place and 15 for third — Norris will be crowned champion if he finishes on the podium regardless of what his rivals get up to.

So...

If Norris wins the Abu Dhabi GP: He wins title

If Norris finishes 2nd: He wins title

If Norris finishes 3rd: He wins title

If Norris finishes 4th: He wins title IF Verstappen doesn't win the race

If Norris finishes 5th: He wins title IF Verstappen doesn't win the race

If Norris finishes 6th: He
