Hungarian Grand Prix 2013: Sebastian Vettel posts fastest times in both practice sessions Mercedes duo Lewis Hamilton and Nico Rosberg improved to fifth and sixth, the former chalking up a day-high total - and a race distance - of 70 laps. That was primarily due to Mercedes coming into this race on the backfoot after being banned for last week's young driver test at Silverstone, where Pirelli's new range of tyres were initially tried. Following a series of blowouts during the British Grand Prix last month, Pirelli were rapidly forced to revise their tyres, opting for a solution that comprises last year's structure with this year's compounds. For Hamilton and Rosberg, the two sessions have been all about obtaining as much information as possible ahead of qualifying and the race. At present, the team's run of six pole positions in the last seven races appears under threat by Red Bull and Vettel, who has won two of the previous three grands prix to open up his advantage over Alonso, with Raikkonen 41 points adrift. Hamilton finished just over half a second down on Vettel, with Rosberg 0.727secs back, while McLaren's Jenson Button and Adrian Sutil in his Force India - on the occasion of his 100th grands prix - completed the top 10 behind Raikkonen. Paul Di Resta, who struggled in session one with set up and found himself 1.5secs behind team-mate Sutil, at least improved in FP2, moving up to 11th on the timesheet and 0.222secs down on the German. Marussia's Max Chilton, who sat out the morning run in favour of reserve Rodolfo Gonzalez, was slowest of all, 5.383secs behind Vettel, and more importantly 1.5secs down on team-mate Jules Bianchi.
