Force India enjoy a strong 24-point lead over Sauber and are not likely to lose the sixth position.
"I think the odds are in our favour, but there's no room for complacency. We need to make sure we get the job done in Interlagos," Team Principal Vijay Mallya said.
"The weather forecast is for some rain and that would introduce an element of unpredictability. That was the case last year when Nico [Hulkenberg] was leading the race, so we have good memories of Interlagos."
"Because it's such a small track every hundredth and thousandth of a second becomes even more critical in qualifying. The lap has a very nice flow with a real variation of corners. There are fast sections, slow corners, elevation changes and off-camber parts of the lap. It may be small, but it has everything you need from a track.

"..It would be great to round off the year with a special result. The weather forecast looks uncertain and it's a track which always generates an interesting Grand Prix. It's the final race for the V8 engines so I really hope we can end the era on a positive note."
"It's quite easy to follow a car onto the straight and there's a big chance for slip-streaming. It's also a difficult circuit to drive despite its short length. It's bumpy and quite low grip, which makes it hard to get the perfect lap.
"I believe the track will suit our car and, should this be a wet race, we could be in a good position for a high-points finish," he said.
