Sahara Force India continued to struggle as Adrian Sutil will start Singapore’s Singapore Grand Prix from 15th position on the grid and Paul di Resta from 17th.
Di Resta was eliminated in Q1 after timing 1:46.121 while Sutil could not make it to Q3 after managing a 1:45.185 in Q2.
Sebastian Vettel secured his fifth pole of the season after his scorching first and only lap (1:42.841) in Q3 and joining him on the front row was Nico Rosberg in his Mercedes.
Lotus' Romain Grosjean was third, followed by Mark Webber in the second Red Bull. Lewis Hamilton was sixth in the second Mercedes and behind him were two Ferrai drivers -- Fernando Alonso and Felipe Massa.
McLaren's Jenson Button, Toro Rosso's Danile Ricciardo and Sauber's Esteban Gutierrez completed the top-10.
Sutil said the team was still fighting to understand and rectify the problem.
"P15 is disappointing because it’s some way off where we were aiming to be. We are just too slow to fight for the top ten at the moment and everyone is working hard to try and understand where we are losing out. All we can do is keep fighting tomorrow and if we do a good strategy we can hopefully gain some places," the German racer said.
Di Resta said, "I think we simply didn’t have enough speed today and all weekend I’ve been struggling with my one-lap pace. It's a tough, long race ahead of us and it’s difficult to overtake, but anything can happen and we will keep fighting," Paul said.
Team Principal Vijay Mallya said, "We've not been able to get the car in the optimal working range and it's clear that we are not getting the most from the tyres. Our long run pace has looked more encouraging so hopefully we can exploit that tomorrow and make the most of events in the race to maximize our strategies."
