Red Bull retained the upper hand as practice continued at the Hungaroring on Friday afternoon, where the ambient and track temperatures reached 31 and 44 degrees Celsius respectively.
As teams ran Pirelli's soft tyres before focusing on long runs on the mediums, Sebastian Vettel carried on where he left off this morning with the fastest time of 1m 21.264s, but team mate Mark Webber was right with him this time on 1m 21.308s, just 0.044s adrift.
Behind them, Romain Grosjean was only 0.153s off Vettel for Lotus with 1m 21.417s, and right behind him came the Ferraris of Fernando Alonso and Felipe Massa on 1m 21.426s and 1m 21.544s. Then there was a small gap to the Mercedes of Lewis Hamilton and Nico Rosberg, on 1m 21.802s and 1m 21.991s. This time Hamilton shared the most laps, 42, with Webber and Saubers Esteban Gutierrez, and Mercedes were encouraged by his pace on his long runs.
Kimi Raikkonen had another adventurous session, including almost making contact with McLaren's Jenson Button as they went through the final corner. The Finn was eighth on 1m 22.011s in his Lotus. Button finished the session right behind him with 1m 22.180s, which was a big encouragement for McLaren. The two Force Indias were next, with Adrian Sutil and Paul di Resta on 1m 22.304s and 1m 22.526s. Sergio Perez was right with the Scot, with 1m 22.529s in the second McLaren.
Williams' Pastor Maldonado, Gutierrez and Sauber team mate Nico Hulkenberg completed the runners beneath 1m 23s, with 1m 22.781s, 1m 22.837s and 1m 22.841s respectively. Jean-Eric Vergne led Toro Rosso team mate Daniel Ricciardo, with 1m 23.369s to 1m 23.411s, with Valtteri Bottas next for Williams on 1m 23.646s.
The Caterhams again outpaced the Marussias, with Charles Pic on 1m 24.325s and Giedo van der Garde just pipping Jules Bianchi, 1m 25.065s to 1m 25.143s. Max Chilton brought up the rear in 1m 26.647s as he took back his Marussia from FP1 tester Rodolfo Gonzalez. The Briton had to overcome a broken cockpit visor midway through the session.
