Senna's race included a solid pit stop by his mechanics and a strong few laps of defending his position.
The result meant that Mahindra Racing finished eighth in the championship standings with 58 points.
In the drivers' championhsip Senna finished 10th after amassing 40 points while Karun was 17th overall as he failed to score points in nine out of 11 rounds.
Changing weather conditions during qualifying left a tricky track to contend with, as a result Senna who was in an earlier group ended in fifth while Chandhok who was caught out with the rain ended the session in 19th.
Over the next few laps the main drama came in the form of Nick Heidfeld who was stuck in the pit-lane entry and pushing his car back. This was cleared relatively easily and meant that the track was soon green to go racing on once again.
As the pit stop window was complete following two strong car changes from the Mahindra Racing team, the cars were released and soon enough a mistake from championship contender Sebasatien Buemi left the track clear for Senna to claim his fifth position back.
