Singapore GP Friday quotes: HRT

Narain Karthikeyan - 24th: "The objective was to adapt to the track because street circuits are always tricky and the important thing was to do laps and gain confidence. The track is very demanding physically, not just because of the heat, but because it's very stop and go. We must be happy with how the session went overall because we did a good job but tomorrow we must take another step forward with the car to progress. And I'm also happy with the trust and support Tata Tea shows in me, with them present on my helmet and drink bottle from this race on."

Ma Qing Hua: "It was fantastic to drive the F112 once again and do it at such a spectacular track. We did a good session and I learned a lot. We took it calmly as the conditions of the track, which was wet, weren't easy. We went out on intermediate tyres and the team wanted me to be comfortable and adapt to the track before switching to softs. I improved my times lap by lap and it was also the first time I'd driven a Formula 1 car in wet conditions, on a street circuit at night time so I'm happy with the result."

Luis Perez-Sala, Team Principal: "The day started with rain and it wasn't easy. Besides, none of the three drivers had raced at the Marina Bay Street Circuit before and we incorporated an aero upgrade so it was a day for learning and they did a good job. Ma, once again, fulfilled his role and took another step in his learning process, which is very positive. Now we must analyze the data before drawing conclusions. With the difficulties that all these factors presents the important thing was to finish the day with no incidents and we did just that."
