Pastor Maldonado insists he is feeling no pressure going into his debut season in F1 after hitting the track for the first time in the new Williams FW33.

The reigning GP2 title winner sampled the new car for the first time yesterday [Wednesday] during the second day of pre-season testing in Valencia and posted the tenth quickest time from his half a day on track.

The Venezuelan will hope to benefit from the experience of team-mate Rubens Barrichello during the season ahead but he insisted there was no pressure on him to get up to speed quickly when racing begins.

"[My aim is] to learn, be really quick, do my best for the team and improve race-by-race," he said. "I don't have this kind of pressure. I will do my best and understand everything, and to do the maximum for the team."

Speaking after his first run in the car on Wednesday afternoon and before a full day at the wheel today, Maldonado insisted he was happy to be behind the wheel of the car even though there are changes to be made to adapt to his own driving style.

"Driving the FW33 and getting a feel for the new car was great!" he said. "My run wasn't that long, but we are concentrating on learning the car to begin with and I was preparing myself for today's programme.

"The feeling is really good. We need to adapt some parts of the car's set-up to better suit my racing style, and maybe I need to adapt as well. We didn't run for too long yesterday, but we will see how we go today and at the forthcoming tests."
