Australian Daniel Ricciardo charged to a thrilling Hungarian Grand Prix victory on Sunday, his second Formula One win for Red Bull, as a drenched track caused chaos among world championship leaders.
Ricciardo, 25, held off Ferrari's Fernando Alonso to take first place in a race which saw several high-speed crashes after a heavy downpour just before the start changed the course of the race.
Britain's former world champion Lewis Hamilton, who started from the pit lane and span on the first lap, ignored Mercedes team orders to let Nico Rosberg pass, and held onto third place ahead of this teammate.
Ricciardo led twice before he fought back to recapture the lead with three laps remaining, following a series of daring passes, to come home clear of Alonso.
Ricciardo's win was executed with great elan and confirmed him as a driver with the potential to be a future champion. He won the Canadian Grand Prix for Red Bull in June and is the only non-Mercedes driver to have won a race this year.
The two Mercedes men had a fierce battle on the track and via the team radio as they tried to make the most of contrasting strategies in changeable conditions following a heavy rainstorm before the start. Two Safety Car interventions played a major part in creating many unexpected moves in a race of surprises.
Brazilian Felipe Massa of Williams finished fifth ahead of Finn Kimi Raikkonen, in the second Ferrari, defending four time champion German Sebastian Vettel in the second Red Bull and Finn Valtteri Bottas of Williams.
Frenchman Jean-Eric Vergne of Toro Rosso was ninth and Briton Jenson Button 10th for McLaren.
