Kubica frustrated by lost points

Kubica, Poland's first Formula One driver, finished seventh on his debut at a wet Hungaroring before he was disqualified because his car was two kilos underweight at the finish due to excessive tyre wear.

"The disqualification was very frustrating, but I am happy that I was able to show some good driving and I hope for a lot of another nice moments in Formula One," said Kubica on his website.

"I did over 50 laps on that set of tyres and towards the end of the race it became really tough. But I managed to finish the race in seventh place. I am happy that I could fight with more experienced opponents on the track and in fact beat some of them in straight fight."

Kubica is expected to keep the second BMW Sauber seat after the team announced they have parted ways with Canadian Jacques Villeneuve.

BMW motorsport boss Mario Theissen was full of praise for 21-year-old Kubica and hinted strongly that he would continue in the race seat.

"In my view it was a perfect first race," he told Reuters before the stewards' acted. "In the beginning it was a bit slippery for him but then he dealt very well with the difficult conditions.

"There's not much more you can ask from a new guy. The best things is that he himself is disappointed, so that's a good promise for the future."
