While Perez suffered an accident in the first lap, Hulkenberg pulled out in the 16th lap because of a mechanical problem.

The pointless result means Sahara Force India's chances of reducing the gap with McLaren are all but over with just two races to go in Brazil and season-ending Abu Dhabi.

Sahara Force India (123) is 24 points behind fifth-placed McLaren (147) in the championship standings and going by the string of unimpressive results in the last couple of race, the Silverstone-based outfit would need a Herculean effort to pip McLaren.

Starting 11th at the grid, Perez crashed into Adrian Sutil's Sauber on the first lap - an incident currently being investigated by the stewards to being the safety car into action.

Perez and Sutil, thus, retired as a result of their first-lap collision.

Hulkenberg, who started 13th on the grid, completed a miserable weekend for Sahara Force India when he withdrew after 16 laps because of engine problem.

Mercedes' Lewis Hamilton won the race ahead of team-mate Nico Rosberg and extended his world championship lead to 24, while Daniel Ricciardo of Red Bull finished third.
