Kamui Kobayashi has admitted it was his own fault he crashed out during the second phase of qualifying for the F1 2011 Singapore Grand Prix - and he has vowed to do his 'utmost' to redeem himself in the race.

Kobayashi, who will now line up in 17th position, added that he simply took too much kerb at the turn 10 chicane, something that launched his Sauber C30 up into the air and pitched his car into the wall.

"I ended up in the wall in Q2 and the accident was my fault. I feel very sorry for the team. I took too much kerb in turn 10, the car jumped too high and this was the outcome. I saw a chance to fight for Q3, but it didn't work out," he lamented.

"I was taken to the medical centre and was quite surprised at how carefully they checked me. However, physically I'm absolutely fine. I will do my utmost tomorrow to fight for points and give something back to the team."

Sergio Perez however had a more fruitful session in the sister car and was unlucky not to make it through to the top-ten shoot-out, demoted right at the end by Force India's Paul di Resta.

"Overall I am pleased with our qualifying performance today, although it is a shame not to have made it into Q3, as it was very close," Perez stated. "My lap in Q2 wasn't really perfect, the one in Q1 was actually better, as I felt more traction then. Nevertheless I'm very confident for tomorrow, as we normally have a strong race pace.

"The circuit is very technical and a driver can easily make a mistake, or with a good performance make a difference. I strongly believe I will finish in the points tomorrow."

"Our car has got faster, so this is positive," summarised team principal, Peter Sauber. "Being a rookie, Sergio is driving here for the first time and has put in a very strong performance. Unfortunately it just wasn't enough to make it to Q3.

"Kamui's performance was definitely good enough to make it into the top ten, but he failed to take his chance when he was riding the kerbs too much and the car left the ground."
