Nico Rosberg secured his fourth straight pole position after topping qualifying for the Mexican Grand Prix.
Rosberg set an initial time of 1:20.120 before lowering his benchmark to a 1:19.480, as no-one was able to improve on the final lap in Q3.
Rosberg’s time proved to be 0.188s faster than Mercedes team-mate Lewis Hamilton, ensuring another front-row lock-out for the squad.
It was the 20th pole position of Rosberg's career and the second time he has racked up four in a row.
Sebastian Vettel was third quickest for Ferrari, ahead of Red Bull’s Daniil Kvyat and Daniel Ricciardo.
Williams collected sixth and seventh courtesy of Valtteri Bottas and Felipe Massa, with Max Verstappen in eighth for Toro Rosso.
Force India only sent Sergio Pérez and Nico Hülkenberg out on track for the final moments of Q3 and the pair finished as the slowest of the runners in the session.
Carlos Sainz Jr. set the 11th quickest time for Toro Rosso, while Lotus claimed 12th and 13th courtesy of Romain Grosjean and Pastor Maldonado.
Marcus Ericsson made it through to Q2 and set the 14th best time for Sauber while Ferrari’s Kimi Räikkönen had a miserable day.
Having stopped on track during final practice, Räikkönen returned to action in qualifying but spun at Turn 1, citing a brake problem with his SF15-T.
Räikkönen set the 15th best time and due to a gearbox penalty is set to start ahead of only the McLaren drivers.
Fernando Alonso was 16th quickest but will drop to 19th due to an engine penalty, though his time was only 1.3s away from the fastest time in Q1.
Felipe Nasr was 17th for Sauber, while Alexander Rossi again managed to out-qualify Manor Marussia team-mate Will Stevens.
Jenson Button was not able to participate in qualifying due to a power unit problem which forced him out of the final practice session.
Button was set to start last even if he had participated in the session due to an array of penalties.
