Sebastian Vettel continued his amazing streak of success in the United States Grand Prix, setting a new record by winning his eighth consecutive race.
In normal racing conditions the Red Bull-Renault RB9 looks unstoppable on any track at the moment. It took a fantastic effort from Lotus's Romain Grosjean to split Vettel and teammate Mark Webber at the end of the race.
But the final race of the season is at a venue with a deserved reputation for unpredictable weather and dramatic racing. The Interlagos circuit in Sao Paulo, Brazil, has seen many rain-affected races and surprising outcomes.
Not least of which was last year's gripping championship-decider, where Vettel was knocked into a spin at the last corner and had to battle his way through the field with exhaust damage to clinch his third title.
Chance of rain in Brazil
The early weather forecast for Sao Paulo shows a chance of rain throughout the weekend. Several drivers will consider that a potential leveller in their efforts to get closer to Red Bull.
Fernando Alonso, winless since his home race in Spain back in May, will be first among them. He has continued to wring the best out of the Ferrari F138 even as it has slipped back from the leading group. Though not quite at the top of his game in qualifying at times, he has a superb touch in slippery conditions as exemplified by his brilliant win at Sepang last year in a very uncompetitive Ferrari. His odds of winning this weekend are 25.00.
Mark Webber is starting his final race as an F1 driver and has won twice before at Interlagos, in 2009 and 2011. Of course he would dearly love to sign off his career with a final victory, and take the tenth win his uncompromising team mate denied him in Malaysia. But in their final season as team mates, Vettel has had an answer for anything Webber can throw at him on the track. Don't expect Webber to get any freebies from his team mate in his final race, but even so his odds are only 4.00.
The Mercedes drivers are also worth a look if the weather is going to be wet, particularly Lewis Hamilton, who is immensely skilled in very wet conditions. He's also back into the groove after his team solved a mystery problem with his car during the last race weekend which was traced back to a damaged chassis. He was on course for victory on wet conditions last year before going out in a collision, and his odds are a strong 18.00.
Hulkenberg the track master
Some drivers have an affinity for particular circuits and one driver who has dazzled in his two previous appearances at Interlagos is Sauber's Nico Hulkenberg.
On his debut in 2010 he took advantage of wet conditions to plant his Williams on pole position. He's had some giant-killing performances in qualifying recently and his odds for pole position this weekend are 150.00.
Last year Hulkenberg led more laps of this race than anyone else in the unfancied Force India. He was trying to re-pass Hamilton for the lead when the pair tangled. Hulkenberg is priced at 100.00 to win on Sunday. He undoubtedly is a very long shot but nor can it be denied he has stunning form at Interlagos.
