Japanese GP: HRT Sunday quotes

Narain Karthikeyan - DNF: "I had a good start and passed Pic on the first lap. The car was working well, it had good pace, and after the first pitstop I was ahead of Pedro and completing a good race. However, we suffered a problem with the car later and, coming in for a second tyre change, the team decided that, as a precautionary measure, it was best to stop. Now it's time to think about Korea and work to take another step forward."

Luis Pérez-Sala, Team Principal: "As it tends to be the case in races like this, I'm happy on one hand because we were competitive; we finished one lap off the winner which indicates that our pace was good. But on the other hand it was a shame that Narain had to retire. He made a good start and was running well but the car suffered a small issue with the bottom part and, for safety reasons, we had to stop him. Now we will see how big the problem is. But overall, it was a positive weekend because we progressed, conserved our tyres better and improved our times. We hope for this progress to continue."
