Max Verstappen, thanks to a clear lap, was the fastest of the last free-practice session in Mexico ahead of Lewis Hamilton and Daniel Ricciardo.
Romain Grosjean, after braking problems on Friday, was the first to head out on Saturday in very different conditions as the sun was out and warmed the track which would allow more grip. Nevertheless, the beginning of the session remained tricky with a lack of grip shown by lock-ups by Lewis Hamilton. Felipe Massa also had troubles warming up his super-soft tyres.
The majority of drivers waited before starting their session as everyone did not have time before 30 minutes. Sebastian Vettel managed to sneak between the two Mercedes while Kimi Raikkonen had been impeded in his flying lap.
The difficult week-end for the Haas continued despite the multiple changes made between Friday and Saturday, Grosjean describing it as a disaster and Gutierrez not understanding how his car behaved. Red Bull seemed to be faster as both drivers went between Hamilton and Vettel.
With ten minutes to go, all the drivers went out for a qualifying run but the traffic was a struggle for everyone except Max Verstappen who took the best time with five minutes to go. No one else was able to beat his time due to traffic on their best lap for the tyres.
Max Verstappen finished the session in the lead ahead of Lewis Hamilton and Daniel Ricciardo. Rosberg, Bottas, Vettel, Raikkonen, Massa, Hulkenberg and Sainz completed the top 10.
