Formula One champion Lando Norris won the Hungarian Grand Prix for McLaren's first victory of the season while Mercedes's Kimi Antonelli extended his overall lead to 50 points.
Red Bull's Max Verstappen was second with Antonelli third after a likely McLaren one-two on Sunday evaporated when Oscar Piastri pulled over with a mechanical failure 14 laps from the end at the Hungaroring.
In an incident-strewn race for the Australian, Piastri capitalised on an error by Norris to take the lead on the third corner.
Both Piastri and Norris were at odds with the McLaren team over their pitstops and Piastri was involved in a collision with Carlos Sainz which cost the Spaniard a five-second penalty.
When Antonelli came in to pit, Norris held a 12-second lead over Pastri.
But three laps later Piastri lost a gearbox on the exit of Turn 3 and his race was over.
Ferrari's Lewis Hamilton, Antonelli's closest title rival, finished fourth on track but dropped to fifth behind teammate Charles Leclerc after a five-second post-race penalty for speeding in the pitlane.
Mercedes's George Russell finished seventh, after a disastrous start that dropped him to 19th, and remained third in the overall standings but 59 points behind his 19-year-old Italian teammate.
