BUDAPEST, Hungary - Double Formula 1 World Champion Lewis Hamilton completed a 2015 Hungarian GP treble on Saturday (July 25) with the fastest lap in final practice after also dominating the previous two sessions.
His best lap was 0.098 quicker than second placed Mercedes team mate and title rival Nico Rosberg.
Rosberg's car stopped at the end of the pits lane in the final minute. He climbed out before helping his mechanics roll the car back.
ROSBERG'S CAR ISSUES
Mercedes technical head Paddy Lowe told the BBC: "It seemed like the engine stalled. We don't know more than that at moment, but it was not planned. We found a few issues last night which we were able to correct and he started in a bit better place today and we saw that in the lap times."
As it happened: 2015 Hungarian GP - 3rd practice
Hamilton, who set a best lap of 1min22.997, has won four times previously in Budapest and will be chasing his ninth pole position in 10 races. He leads closest rival Rosberg by 17 points.
Ferrari's Sebastian Vettel was third fastest, but team mate Kimi Raikkonen was sidelined by a water leak and was only 16th, while Russian Daniil Kvyat was fourth for Red Bull.
Force India got both their cars back out on track after sitting out Friday's second practice following Mexican Sergio Perez's big crash in the opening session.
Nico Hulkenberg was sixth fastest while Perez was 15th on the timesheets.
