A phenomenal victory in the Brazilian Grand Prix from Max Verstappen landed a crushing blow to Lando Norris' hopes of a maiden Formula 1 title.
Following a domineering start to the campaign, three-time world champion Verstappen has been anxiously looking over his shoulder as the once seemingly imperious RB20 is usurped by Red Bull's rivals.
McLaren have now overhauled Red Bull at the top of the Constructors' Championship and their remarkable improvement had thrust Norris into title contention, with the Briton sealing his first career win in Miami before adding two more triumphs in Zandvoort and Singapore.
However, following a chaotic race at Interlagos which saw Verstappen climb from 17th to 1st, Norris' quest to catch the Dutchman now appears nigh-on impossible.
We've looked at the permutations and how Verstappen can clinch his fourth world title in Las Vegas.
Norris is currently 62 points behind Verstappen with three Grand Prix remaining, which includes one sprint race in Qatar.
Las Vegas hosts the final race in the Americas before moving across to the Middle East where Formula 1 will visit Qatar and Abu Dhabi.
Of the remaining three races, there is one sprint race.
A maximum of 86 points is on offer between now and the end of the season.
Of those 86, 78 is available from the races, which includes the bonus point awarded to the driver who sets the fastest lap of the race. A maximum of eight points is on offer from the sprint.
Yes, Verstappen will be crowned world champion if he takes victory in the Las Vegas Grand Prix.
In fact, should Verstappen finish ahead of Norris in any position, he will retain his crown for a fourth successive year. The Red Bull driver can even afford to finish behind Norris, providing the Briton doesn't outscore him by more than two points.
Norris can take the title battle to Qatar if he outscores Verstappen by three or more points in Las Vegas.
