Buemi says penalty too severe

The Swiss driver got a stop-and-go for speeding in the pitlane, a penalty that ruined all his chances of fighting for the points.

Buemi, who finished in 13th position, felt a drive-through would have been much more fitting.

"I made a good start, passing Rosberg and was running well, closing up on Kobayashi and Schumacher, but at my first pitstop, I had the impression that the pitlane speed limiter had not been engaged.

"I immediately pressed it again, which deactivated it, so I sped in the pitlane and picked up a ten second stop-go penalty, which I felt was a bit severe, as usually you get a drive-through penalty which loses you less time.

"After that I gave it my best shot but it was not enough to get a reward for the work, as I felt we could have got the Force Indias and at least finished ninth. I only changed tyres twice and it's true that the last few laps were very difficult because of the degradation."

Team-mate Jaime Alguersuari also endured a disappointing race, the Spaniard at a loss to explain his problems during the event.

He finished in 14th.

"I need to analyse this race with the engineers, because to be honest, I don't really understand what happened: we were slow and the tyre degradation was very high, higher than on Friday," he said. "I struggled to clean the graining off the front tyres and was losing performance with every passing lap.

"On the positive side, I made a good start, gaining a few places. But soon I found I could not keep up with the guys in front. Given the difficulties I had, I feel that finishing the race was in itself an achievement and the best I could do today."
