Dominant triumph at the United States GP overextended Hamilton’s lead over nearest title rival Sebastian Vettel to 66 points, but the German’s second-place finish resulted the championship race was extended for a further week.
Mathematically, Vettel could still win the title for Ferrari if Hamilton has a three-race failure of epic proportions.
Hamilton has scored points in every race this season and hasn’t missed a podium after the first-half of the season.
Here’s the full-maths for how the drivers’ championship title can be decided this weekend…
The high-altitude Mexican GP circuit could well favour Ferrari more than Mercedes, but Hamilton won from pole position last year and arrives this time with a haul of five victories from the last six races.
The pressure, what little there is remaining, is all on Vettel. It will take the biggest comeback the sport has ever seen to deny Hamilton now, even if Mercedes continue to urge caution.
“I can imagine every scenario,” Mercedes team boss Toto Wolff told reporters in Texas on Sunday night when asked if he could envisage Hamilton not winning.
“This is motor racing. Sebastian had a DNF (did not finish) in Singapore, scored little in Sepang (Malaysia) and DNF at Suzuka.
“So it is not done until you’ve mathematically achieved it,” added the Austrian, whose team have already wrapped up the constructors’ championship for the fourth year in a row.
