Mercedes driver George Russell was handed victory in Sunday's Austrian Formula One Grand Prix after leading duo Max Verstappen and Lando Norris clashed wheels and flew out of contention.
Briton Russell stayed out of trouble behind them and glided by for his second F1 triumph after winning in Brazil in 2022.
Triple world champion and standings leader Verstappen had looked poised for an easy victory on his Red Bull team's home track after winning the sprint race and topping qualifying on Saturday.
But a slow second pit-stop allowed Norris to close up behind him and on a third attempt to pass the Dutchman, their wheels touched. Norris had to retire while Verstappen limped home fifth - despite being handed a 10-second penalty for causing the collision with Norris.
McLaren's Oscar Piastri was second and Ferrari's Carlos Sainz third.
"Yabba, Dabba Do!" said Russell over the radio after snatching victory. "It's not over until it's over."
It was Mercedes' first win in 36 grands prix.
Verstappen's procession ended by slow pit-stop
Verstappen had sped away from the pack from pole, with all drivers managing the first lap without any major incidents.
It looked like it would be a mere procession for Verstappen, chasing a third win in a row this season and a fifth victory at Spielberg.
The first bit of drama came in the first pit-stops where Verstappen's car almost hit Norris as he boxed but the Dutchman avoided a penalty for unsafe release.
Norris said on the radio: "He launched right at me. He launched straight into me. I couldn't turn right to the box."
When they both boxed a second time, Red Bull's mechanics were uncharacteristically slow but Verstappen still re-entered the race just in front.
Norris was on his tail though and the Briton tried to pass, only to complain that Verstappen had blocked his racing line. Norris then did overtake but immediately gave Verstappen the place back after exceeding track limits.
It set up an exciting last 10 laps, with Norris getting past again but appearing to force Verstappen off the track, with the champion somehow emerging ahead.
The next attempt on lap 64 of 71 saw both cars clash and Verstappen's tyre blew, knocking him down the pack. Norris was then given a 5-second penalty for leaving the track too often but damage to his car was too much anyway and his race was over.
Disappointment for Red Bull at home race
Thousands of orange-clad fans in the stands were hoping to see another Verstappen triumph but in the end saw some high drama on the central Austria track owned by the Red Bull energy drinks empire.
Officials said around 302,000 fans had watched the racing over the three days on the undulating circuit, but there was no Red Bull car on the podium at the team's home race.
The Dutch fans could at least celebrate Verstappen nudging 81 points ahead of second-placed Norris in the overall standings.
The 26-year-old Verstappen has been slightly less dominant this season, now missing out in four races already compared to the three he did not win in the whole campaign of 22 grands prix last season.
But he is still on course for a fourth straight world title in this record season with 24 races.
His clash with Norris followed another apparent spat between Red Bull team principal Christian Horner and Verstappen's father Jos. Reports have said ex-F1 driver Jos was prevented from racing in a legends race at the Red Bull Ring this weekend, but Horner has denied having anything to do wih the decision.
Mercedes' seven-times champion Lewis Hamilton was given a five-second penalty for crossing the pit entry line and ended up fourth.
Red Bull's Sergio Perez received the same punishment for speeding in the pitlane and finished seventh behind the impressive Nico Hülkenberg in the Haas.
Ferrari's Charles Leclerc also had a difficult afternoon, having to pit for a new front wing and coming home 11th.
