Fernando Alonso has the championship lead on his side as he aims to clinch the Formula One (F1) world title in a historic finale Sunday in Abu Dhabi.But in a season of roller-coaster rides for all the stars, Red Bull drivers Mark Webber and Sebastian Vettel and McLaren's Lewis Hamilton are also in the frame.
It is the first time in F1 history that four drivers are in the title race ahead of the season-ender.
A simple engine failure in Alonso's Ferrari could for instance open the door for the others, he may be shunted off the track by another driver, make a mistake himself or have yet another negative experience with the safety car as has happened already three times this season.
However, Alonso has a third career title in his own hands as championship leader. He has amassed 246 points from 18 of 19 races, with Webber on 238, Vettel on 231 and Hamilton on 222.
Under the current system, the top 10 drivers get points in a 25, 18, 15, 12, 10, 8, 6, 4, 2, 1 format.
Alonso has done his maths and says 'I just need to finish second. It does not matter who wins in Abu Dhabi if I finish second'.
The Spaniard can also afford third place if Webber does not win, and fourth or fifth if Webber and Vettel do not win.
Webber will secure the trophy if he wins and Alonso comes no better than third. A team order of sorts may be used if Vettel leads from Webber and Alonso in the final lap, as Ferrari also ordered Felipe Massa to let Alonso pass for victory at the German GP.
