Lack of pace spoils Barrichello's day

The Honda driver, starting his record 257th Formula One grand prix, struggled for pace during the race and had to settle for 14th position, a lap down.

The Brazilian, now the most experienced driver in Formula One history, admitted he was disappointed with the speed of his car.

"It was a frustrating race for us today," said Barrichello, yet to score a point this year. "Unfortunately we did not have the pace to compete and overall I'm disappointed with the performance of the car.

"I suffered from understeer and traffic in my first stint so we stopped a little bit early to try and get me out into some space. From then on, it was an uneventful run to the end of the race.

"We have a lot of work to do over the next couple of tests to try to find some pace."

Teammate Jenson Button also had a poor day, despite expecting the Istanbul circuit to suit his car better than Barcelona, where he had finished in sixth.

The Briton wound up 11th, also a lap behind race winner Felipe Massa.

"Although I managed to improve slightly on my start position, it was a disappointing race for us," he said. "The start was clean and I had a pretty good first lap, however our pace wasn't as good as we expected it to be during the race.

"I had a problem on my first stint with the front tyres, caused by the brakes overheating, which cost me a bit of time.

"We then changed our strategy to a one-stop which worked pretty well. Unfortunately the difference in fuel loads really tells here so it was difficult to hold back the quicker cars behind me who were two-stopping.

"We need to make some further improvements to the car before we are able to challenge for the points again."
