Oscar Piastri has won the Formula 1 Spanish Grand Prix from pole position, while world champion Max Verstappen had a moment of fury and appeared to crash into a rival.
Piastri extended his narrow lead in the F1 drivers' championship to 10 points over McLaren teammate Lando Norris, who was second in Barcelona, with Ferrari's Charles Leclerc claiming third.
But the major talking point out of the race was Verstappen appearing to deliberately drive into Mercedes driver George Russell.
Verstappen was running third when a late safety car bunched the field. While other teams were able to put soft tyres onto their cars, Red Bull only had a set of the slower hard compound left.
Off the restart, he immediately fell to fourth behind Leclerc, and then was forced up the escape road by Russell, who was trying to overtake.
Verstappen retained fourth, which appeared to be fair, but Red Bull advised him to give up the position, believing he would receive a penalty for maintaining fourth place by going off track.
An irate Verstappen then appeared to slow down, let Russell get past him into a corner, then kept his car pointed straight to hit Russell.
In an interview with Sky Sports, Verstappen was asked directly if the move into Russell was deliberate.
"Does it matter?" he replied.
"I prefer to speak about the race, [rather] than just one single moment."
In another interview with F1TV, the defending four-time world champion again offered no interest in discussing the moment.
"I don't need to say anything about it," he said.
"It doesn't matter anyway, you know. We can't be critical about anything."
Verstappen crossed the finish line fifth but was handed a 10-second penalty, demoting him to 10th.
Nico Rosberg, the 2016 world champion, believed Verstappen was lucky not to be shown a black flag and disqualified from the grand prix.
"It looked like a very intentional retaliation. Wait for the opponent and go ramming into him, just like you felt like the other guy rammed into you," he said on commentary for Sky Sports.
"That is something that is extremely unacceptable.
"If you wait for your opponent just to bang into him and crash into him, then that's a black flag."
Verstappen's actions have been called into question previously, including last year in Mexico when he was accused of deliberately forcing Norris off the track.
In 2021, in Saudi Arabia, Verstappen made contact with Lewis Hamilton after he was instructed by his team to let the then-Mercedes driver through to avoid a penalty.
[standings widget]For Russell, he said the situation was puzzling, but he was not going to bother mulling over it.
"I've seen those sort of moves before in go-karting and simulator racing, but never in F1," he told the media.
"It was a bit surprising. It cost him and his team a lot of points."
At the front, Piastri was clinical to secure his fifth grand prix win of the season.
The Australian got off to a great start and was not challenged for the lead at turn one.
Verstappen getting ahead of Norris allowed the Australian to build a nice gap in front, as McLaren clearly had the fastest car.
A late safety car, called after Mercedes driver Kimi Antonelli suffered a power failure and had no control of his car going into gravel, was the only potential moment of peril for Piastri.
But he handled the restart with aplomb and took the chequered flag.
"Hard to complain, it has been a great year and this weekend has been exactly the kind of weekend I've been looking for," he said.
"It is a lot of fun winning races at the moment."
Look back at how the action unfolded in the ABC Sport live blog.
