There’s huge sense of excitement and expectation in the Camp of the Silver Arrows today as Lewis Hamilton leads the line of 20 drivers who zoom off tonight in Texas for what is to be one of the most watched races in the 2017 Formula One calendar.

Hamilton comes to the US GP with a 59-point advantage over closest rival Sébastien Vettel who is a further 13 points ahead of Mercedes driver Valterie Bottas. The Circuit of the Americas has favoured Lewis Hamilton since joining the Formula One calendar in 2012 with 4 wins out of 5, he also clinched his most recent World title here in Austin with a win over Nico Rosberg in 2015.

With Vettel and Bottas still in with a mathematical chance of nicking the drivers title, the following are the conditions that guarantee titles for Mercedes and Lewis Hamilton tonight.

Driver’s Championship

Hamilton needs to outscore Vettel by 16 points and Bottas by 3 points to clinch the title.

That means:

If Hamilton wins the race, he is world champion if Vettel finishes sixth or lower;

If Hamilton finishes second, he will be world champion if Vettel finishes ninth or lower AND Bottas doesn’t win;

If Hamilton finishes third or lower, he doesn’t win the title tonight and the title race goes on to Mexico.

Constructor’s Championship

Mercedes hold a 145-point lead over Ferrari in the constructor’s championship and they will surely win the title today in Austin if they have a lead of at least 129 points over the Scuderia at the end of the race. That means Ferrari are to have at least 17 more points than Mercedes at the end of tonight’s race to continue to have a mathematical chance of winning the title.

If either Mercedes driver wins the race, the team surely seals the Constructor’s Championship.

The US GP starts tonight October 22 from 8pm
