Hungarian GP: Sebastian Vettel surprised by Red Bull's advantage

The world champion topped the times both in the morning and in the afternoon sessions, with team-mate Mark Webber second in both.

Vettel said it was still too early to get carried away, but conceded it was a very solid start for his team.

"I think it is too early to tell. First practice and second practice were very good for us, which I think is a bit of a surprise," said Vettel.

"You try to do what you can and you don't know where the others are, but I think tomorrow will be closer and we have to make sure we get everything out of the car tomorrow."

He added: "It's nice when you feel in control of the car and you can play around. I think the car suits the track.

"There is still a bit of work to do but we need to make sure we get everything out of the car tomorrow."

Webber, who finished just 0.044s behind Vettel in second practice, was also upbeat about the day's work.

"We will see what the opposition are doing a little bit tonight, generally we focused on ourselves today and did a pretty good job, I must say," he said.

"We had a bit of traffic I think, but apart from that it was pretty smooth, to be honest. Everyone is doing their own programme.

"In the end we kept our head down, shifted away at our own agenda and we don't have a huge amount to go through tonight as the car ran seamlessly. That is a nice bonus in terms of data tonight."
