Red Bull are now over 100 points clear of Ferrari at the top of the championship with six races to go – and although that means a total of 258 points are up for grabs, current form suggests it is extremely unlikely that they will be caught.
But behind them, there are two intriguing battles.
And in F1, points really do mean big prizes.
Figures are hard to find, but reports suggest some $700m (£436m) is handed out to the teams in prize money. Ferrari is understood to automatically get 2.5 per cent ($17.5m) through a private deal just for being there, and the remaining $685.5m gets distributed among all the teams.
Half of that figure is split evenly among those that finished in the top 10 for two of the last three years. The other half is paid out on a sliding percentage scale based on championship positions – reportedly 19 per cent to the champions then 16, 13, 11, 10, 9, 7, 6, 5 and 4.
So Ferrari and Mercedes are not only racing for pride, they are racing for the sum of $10.2m. That figure may be a drop in the ocean compared to their £300m+ budgets, but for Mercedes in particular, who are constantly having to prove the worth of F1 to their car manufacturer bosses, it would be a handy bonus.
It could even play a part in deciding driver line-ups for 2014.
According to reports, McLaren spent $23.6m on their two drivers for this year, of which $21.6m went on Button and $2m on Perez. Force India spent a combined total of $1.2m on their two drivers.
McLaren signed Sergio Perez on racing merit, but he did bring some significant funding with him. Last year they earned $10.3m more in prize money than the maximum possible for them this year. If they end up sixth, it would be a $13.7m deficit, and when you look at that in terms of Button’s salary, it becomes quite significant.
Force India, meanwhile, refused to take on pay drivers this season – running the talented if lower-tier line-up of Paul di Resta and Adrian Sutil in the hope that they could improve on the seventh place they finished in the constructors’ championship last year.
By all-but securing sixth, they already stand to gain $6.8m more than last year – but the new engines for next season reportedly cost double the price of this year’s, so that and more will be needed to pay the bills of engine suppliers Mercedes.
And that all makes the extra $3.4m quite significant.
Right now, it’s not looking good for Force India because since the German Grand Prix, when the design of Pirelli’s tyres was changed, the relative form between them and McLaren has flipped completely.
Force India went to Germany on 59 points with McLaren 22 behind on 37. Since then, McLaren have scored points in every race, adding 54 to their total, while Force India have managed just 3 more to take them to 62.
Singapore last weekend was crucial, as Di Resta retired from a potential sixth place with seven laps to go and Sutil only managed 10th, leaving McLaren to stretch the gap by another nine points as they finished seventh and eighth.
Force India says Suzuka and other faster tracks should suit them, but unless they make a dramatic turnaround, missing out on those extra millions could mean some hard decisions for 2014...
