Brazilian GP: Force India Friday quotes

Nico Hulkenberg - 10th/11th: "You certainly felt the heat today and the car was quite loose and difficult to drive at times. Apart from that it was business as usual - doing the long runs and getting the tyre data. We also had an extra set of the 2013 tyres available this morning so it was interesting to get a taste for them and do a direct comparison with this year's tyres. It's difficult to judge where we stand at the moment, but we have all the information we need, so it's just a case of trying to understand things more tonight to be ready for tomorrow."

Jakob Andreasen - Chief Engineer: "Two productive practice sessions today have left us well prepared going into the weekend. There were some aero test items on the cars this morning and we also had a chance to sample the 2013 development tyres. That proved extremely valuable and we made the most of the opportunity to try and get a head-start on next year. In the afternoon the temperatures continued to rise, with the track reaching a high of 55°C - one of the highest peaks we have seen all year - and the drivers said the car was sliding around quite a lot, as you would expect in such conditions. More warm weather is forecast for tomorrow, unless the rain arrives, and there is also a high risk of rain on Sunday."
