McLaren pair Lewis Hamilton and Jenson Button topped the times in the opening practice session for the Hungarian Grand Prix, with Friday running getting underway with a relatively uneventful 90 minutes on track at the Hungaroring.
Hamilton topped the standings for just under an hour and eventually posted a best time of 1min 22.821secs which would remain unbeaten despite the best efforts of the field behind. Team-mate Button was the only person to get close however, setting the only other time under the 1min 23secs marker to end the session just a tenth of a second further back.
Championship leader Fernando Alonso moved into third late in the session to put him ahead of the Mercedes of Nico Rosberg, with his team-mate Michael Schumacher rounding out the top six – the German pair split on the times by the Lotus of Romain Grosjean.
Grosjean was once again running with his car in its regular configuration, with team-mate Kimi Raikkonen continuing to evaluate the new rear wing that appeared on the Lotus car in Germany last weekend. The session wasn't without issues for the Finn with a heating issue during mid-way through, although he was lapping with DRS in use on the new part by the time the chequered flag dropped.
Raikkonen would end the session eighth quickest, just behind the second Ferrari of Felipe Massa, with Valtteri Bottas for Williams and the Sauber of Sergio Perez completing the top ten.
Red Bull meanwhile had a quiet start to the weekend, with Mark Webber down in 13th place and Sebastian Vettel two places further back.
There were no major issues on track throughout the session, although a number of drivers did run wide across the asphalt run-off. Pastor Maldonado also took a trip through the gravel having come up behind the slow Caterham of Heikki Kovalainen on track.
