Red Bull's Sebastian Vettel dominated free practice at the Hungarian Grand Prix Friday while Ferrari's Felipe Massa returned to the scene of his near-fatal accident with the fourth fastest time. Germany's Vettel, who will be chasing his fourth pole in a row on Saturday and seventh of the season, was quickest in both sessions with a lap of one minute 20.976 seconds in the morning and 1:20.087 after lunch. Australian team mate Mark Webber was second quickest in the opening session but Ferrari's Fernando Alonso was Vettel's closet rival on a warm afternoon at the Hungaroring. Poland's Robert Kubica, preparing for the nearest thing to a home race, was third and seventh respectively for Renault. Red Bull have started 10 of the 11 races so far on pole position but have failed to convert that advantage in qualifying into regular race day success. Vettel has won twice and Webber three times but McLaren are leading both Formula One championships with Lewis Hamilton and Jenson Button. World champion Button, who took his first grand prix win with Honda in Hungary in 2006, was fourth fastest in the morning while overall leader Hamilton was 18th. Alonso was a controversial winner in Hockenheim last weekend, after team mate Felipe Massa was instructed to let him pass for victory. Massa was back on track at the Hungaroring for the first time since his big accident in qualifying for last year's race. The Brazilian wasted no time in getting back, completing the first timed lap of the session.
