(CNN) -- Red Bull set the pace again in practice as Sebastian Vettel recorded the fastest lap time in both sessions Friday ahead of this weekend's Hungarian Grand Prix in Budapest.
The German, who trails championship leader Lewis Hamilton of McLaren by 21 points, clocked his best time of one minute and 20.087 seconds in the afternoon.
The 23-year-old's time was almost half a second quicker than last year's winner in Hungary, Fernando Alonso, who was second for Ferrari.
Vettel told Formula One's official website: "I think this morning didn't really give a clear picture of each team's pace, but this afternoon it was tighter.
"The Ferraris seem very quick again here, on both the long and short runs.
"They will be quick again tomorrow and we also shouldn't forget the McLarens; they have proven many times this year that they can make a step forward from Friday to Saturday.
"It's a difficult track here, quite bumpy and rough, but the car feels good."
Vettel's teammate Mark Webber was next in third, while Ferrari's Felipe Massa clocked the fourth best time on an emotional return to Hungary.
It was the Brazilian's first visit to the Hungaroring circuit since suffering near-fatal head injuries last year in a horror crash in qualifying.
Renault continued recent improvements with a good showing in the second session with Vitaly Petrov of Russia in fifth and Pole Robert Kubica seventh.
But it was another disappointing showing for McLaren, as Hamilton finished sixth ahead of teammate and reigning world champion Jenson Button in ninth.
German driver Nico Hulkenberg of Williams managed eighth, with compatriot and seven-time world champion Michael Schumacher in 10th fastest.
Schumacher's Mercedes GP teammate Nico Rosberg, who finished eighth in the morning session, failed to get to grips with the slightly cooler track surface in the afternoon, finishing down in 13th.
Saturday sees final qualifying for Sunday's race.
