As if comprehensively topping both Friday practice sessions with both drivers, it appears that Red Bull have only just begin to show their hand at the Hungaroring ahead of this weekend's Hungarian Grand Prix.
"It was a good day for us," said Vettel after the end of Free Practice 2 on Friday afternoon, which saw him set the fastest lap of the day with a time of 1:21.264s, 0.044s clear of his team mate Mark Webber.
"Practice one and practice two were very good for both of us, which I think was a bit of a surprise," he continued. "I think the car suits the track but I think there is still a little bit of room for improvement.
"There was quite a lot of work in the background," he insisted. "But it was obviously nice when you feel in control of the car and you can do what you like to play around.
"Obviously you try to do what you can but you don't know where the others are," he added. "I think tomorrow will be close so we have to make sure we get everything out of the car tomorrow."
In the afternoon session, Romain Grosjean came closest to breaking up the Red Bull monopoly at the front as he ran his Lotus to within 0.153s of Vettel's benchmark time, putting him narrowly ahead of Ferrari's Fernando Alonso. And it was Alonso that Mark Webber tipped to be the big threat for pole on Saturday.
"It looks pretty tight over one lap," Webber insisted. "The Ferraris are not hanging around. Fernando's always been strong here, I had a race with him in F3000 back in 2000 so the old dog's still there.
"There are some quick guys, we're not resting," he added. "We're not going to be leaving the track early tonight, we've still got work to do."
Webber said that Friday had been a fairly routine day at the office, although the short, tight and twisty nature of the Hungaroring had inevitably led to some small frustrations as the team attempted to work through its planned program of work.
