Mexico City: Sahara Force India completed two busy practice sessions during the first day of action for the Mexican Grand Prix as the Formula One championship returned to the country after a 23-year absence.

Sergio Perez said, “It's been a very special day from a personal point of view, but my focus remains on the work we have to do to prepare for the race. The circuit is quite challenging and, as we expected, very slippery. In the middle sector there is a lot of movement with the car and it's very difficult to get the car to stay on the right line. The altitude affects the levels of downforce pretty dramatically, so you end up being fairly light no matter what levels you are running. The conditions are very tricky but they're the same for everyone, so we will need to adapt. I want to give all the Mexican fans who come to the track this week something to celebrate on Sunday: it was great to see so many of them today and I am feeling optimistic that I will be able to deliver a good result for them.”

Meanwhile, Nico Hülkenberg said, “The circuit is definitely a big challenge, but it's good fun to drive. It's very technical and quite tricky to get it right. Sectors one and two, after the straight, are quite twisty and low-speed: the grip levels are very low, due to the new tarmac, and it's very easy to make a mistake. I am happy about the direction we are taking: there is still a lot to be done to find some more performance, but we are at a good starting point and I am sure that looking through the data will help us progress. We were able to complete a lot of laps, using both tyre compounds, and I think we have a pretty good understanding of where we are ahead of qualifying tomorrow.”
