Sahara Force India completed a busy practice programme at Interlagos today in preparation for Sunday's Brazilian Grand Prix.

Nico Hulkenberg: "It was a standard Friday with lots of laps covered and plenty of data collected. Track temperatures were high for most of the day so it didn't really matter that there were a few spots of rain because it evaporated very quickly. There is still a lot of work to do ahead of qualifying because I'm not completely happy with the balance and we need to work more on understanding the tyres. With such a short lap the grid is always tight here so it's important we find some more performance tonight."

Sergio Perez: "We learned a lot today with a big test programme this morning. Everything went smoothly and it has given us plenty to analyse because we ran different programmes with each car. The afternoon was standard for us - collecting the tyre information and continuing to improve the car. I think we need to change a few things tonight, but I'm confident we have enough information to make sure we choose the right direction."

Robert Fernley, Deputy Team Principal: "Overall we've enjoyed a fairly routine day of Friday practice, which allowed us to work through most of the items on the job list. Interlagos is a fairly unique track in terms of its layout so we put our focus on the twisty second sector and making sure the cars work well through those low-speed corners. Both Nico and Checo explored some different set-up directions during the day, but ended the afternoon session fairly content. I think we are in good shape heading into the weekend and will be targeting Q3 for both cars once again."
