Luizzi pleased with Silverstone result

"I had quite a good race, it felt like a long one," said Liuzzi after finishing in 13th position.

"It was a shame that in the early stages I could not keep up with the group ahead of me, because I had too much understeer. It was the right choice to change our strategy during the race.

"Apart from the understeer the car went well and it was a good performance given that we had always known Silverstone would be a tough track for us, as the V10 was never going to be ideal round here.

"So, to sum it up - a good result."

American Scott Speed was unable to complete the race after making contact with Ralf Schumacher on the opening lap.

Speed managed to return to the pits, but the repairs took too long and the team decided to retire him.

"I had a really awesome start and got past Tonio and Christian," said Speed. "I tried to get by Ralf as well in the left hander at Becketts, as he seemed not to have got a good start and I had a lot of grip. I came up alongside him in the right hand part and then we just got tangled up together as I went round the outside of him.

"I don't think he was expecting me to be there. It was just a racing incident, but unfortunately it was the end of our day, as I had bent a track-rod."
