After a good show in Abu Dhabi and India, Sahara Force India had created a good lead over nearest rival Sauber and despite not scoring any point in the final two races they comfortably beat them by 20 points.
Paul di Resta was 12th in the drivers' championship with 48 points, 19 more than Adrian Sutil, who was 13th.
Despite scoring more points, it is being speculated that the Scot will not be able to keep his race seat at Force India as Nico Hulkenberg is tipped to replace him.
Hulkenberg had raced for Force India last year but moved to Sauber.
