Hungarian GP: Sebastian Vettel extends lead
Ferrari's Formula One championship leader Sebastian Vettel took pole position at the Hungarian Grand Prix on Saturday.
Ricciardo then passed his Dutch teammate into turn two to move into fourth before Verstappen hit him as they came through the corner.
The incident did irreparable damage to Ricciardo's Red Bull, which went off the circuit and was spilling a lot of oil.
It also sparked an angry reaction from Ricciardo over the team radio.
"Someone hit me. Is that who I think it was?" Ricciardo asked his race engineer.
"Yes," came the reply from Red Bull, and then Ricciardo did not mince his words.
"F---ing sore loser," Ricciardo added.

While the incident ended Ricciardo's race, Verstappen was given a 10 second penalty but still managed to finish fifth as he barrelled down on the Mercedes of Hamilton at the death.
The race was won by Ferrari's Sebastian Vettel, who overcame steering difficulties to extend his championship lead over rival Hamilton to 14 points heading into the summer break.

The four-time Formula One champion made a decent start from pole position, crucially holding off teammate Kimi Raikkonen on the long straight into turn one. On a Hungaroring track where overtaking is notoriously hard, there were limited chances to catch him after that.
"I'm over the moon. It was a really difficult race. I had my hands full," Vettel said.

"The steering started to go sideways and it got worse. I really had to stay focused the whole race."
Ricciardo, however, was fuming when asked by reporters at the circuit about the collision between the two Red Bulls.

"That was amateur to say the least," Ricciardo said.
"It's not like he was trying to pass. He doesn't like people passing him. I didn't really know what happened. It's just frustrating – it was not even an overtaking move.

"It was an emotional response."
Ricciardo called for his 19-year-old teammate to take full responsibility for the error.
"In that moment the team said sorry and they will speak to Max," Ricciardo said. "Let's see if he acts his age or like a man about it and admits the error.
"I could go and call him names after the accident but if he starts bringing in other excuses in then we will have a problem."
Verstappen offered up an apology immediately after the race.
"It is of course not what you want," Verstappen said of the incident.
"The start was actually quite good but then we were both fighting for position into turn two. I had a car in front of me and I locked up and then I was a passenger.
"It was never my intention to hit anyone and especially my teammate, who I have a good relationship with.
"I apologise to Daniel and I will speak to him in private. We will sort it out."
It was not he only incident to spill into an off-track war of words. Renault's Nico Hulkenberg branded Haas rival Kevin Magnussen the "most unsporting" driver in Formula One.
Hulkenberg had been frustrated by the Dane forcing him off as he tried to pass at turn two in the closing stages of the race.
The Renault driver retired in the pits while Magnussen collected a five-second penalty but finished 13th.
"When it comes to racing, he's just nasty," said Hulkenberg, who 'congratulated' Magnussen in front of television reporters in an angry exchange that turned the air blue when the Dane replied.
"Hard defending is fine but what he does is just ruthless and sending people into the wall."
Magnussen had earlier criticised Hulkenberg over the team radio for an incident involving his French Haas team mate Romain Grosjean.
"If you can do what Hulkenberg did to Romain, then it's going to be a dirty race," he said.
Haas team principal Guenther Steiner defended Magnussen, calling Hulkenberg a bully.
"He got away a long time with it and maybe now it's time that somebody stands up to him," he added. "He's a good driver, he doesn't need to be like this."
It was Vettel's 46th career win, coming in ahead of teammate Raikkonen for a Ferrari 1-2.
"Grazie! Forza Ferrari!" a jubilant Vettel shouted on the team radio after crossing the line for his fourth win of the season.
