Lewis Hamilton started his Hungarian Grand Prix weekend as he intended to continue, leading both of Friday's free practice sessions with championship-leading Mercedes teammate Nico Rosberg behind.
The winner of the last two Hungarian Grands Prix lapped the Hungaroring circuit outside Budapest with a best time of one minute 25.814 seconds in the morning and 1:24.482 in the afternoon.
Rosberg was second fastest in both, 0.183 and 0.238 slower than the 2008 champion in the sessions with track temperatures rising to a sweltering 55 degrees Celsius after lunch.
Ferrari's Kimi Raikkonen and Fernando Alonso were the closest to the dominant duo, who have won nine out of 10 races so far between them, in the morning with third and fourth places respectively on the timesheets.
However Red Bull's quadruple champion Sebastian Vettel, who has never won in Hungary, was third fastest in the second practice with Alonso fourth.
Hamilton is 14 points adrift of Rosberg, despite having won five races to the German's four, but has a far better record in Hungary.
