A bright and sunny day heralded the arrival of first practice in Hungary, and it was all about Red Bull. Sebastian Vettel went out reasonably early but had to return to his garage with a brake problem. He wasn't the only one struggling - Felipe Massa had a few offs, Jean-Éric Vergne spun off into the gravel, and Kimi Räikkönen had a brief airbox fire and found himself with wet boots due to something leaking. But when Vettel returned to the track, he posted the fastest time of the day, with Mark Webber behind him.
