Sao Paulo, Nov 1 (UNI) Force India drivers Giancarlo Fisichella and Adrian Sutil had to struggle with low grip during the practice session on the rain hit bumpy Interlagos track here on the eve of the Brazilian Grand Prix.
The grand Prix is the last race of this year's FIA Formula One World Championship.
''We didn't have any problems today so we could get through our schedule as planned. I was quite happy with my performance and we can see how the tyres are working now,'' Sutil said after the practice.
Heavy rain before the morning session left the 4.309 km track damp and cool and both drivers struggled to get heat into the harder tyre compound available in this event.
Fisichella and Sutil duly improved their times by one second to set the 19th and 20th quickest times of the afternoon, just over a second from the fastest lap of the day.
They finished two 90-minute practice sessions, working through the standard programme of tyre and set-up evaluation.
''The soft ones seem to be better compared to the medium tyre at the moment. We'll study the data and work on it for tomorrow,'' Sutil added.
