Luxury carmaker BMW's new chief executive, Harald Krueger fainted on stage at the Frankfurt auto show on Tuesday.
Mr Krueger, 49, collapsed as he was commenting on BMW's latest models during a news conference.
Two men escorted him off stage.
A BMW spokesman said over the public address system: "I'm a bit lost for words."
It was the first appearance at a major auto show by Mr Krueger, who took the helm as CEO in May.
BMW later said: "Harald Krueger experienced a moment of dizziness. As a result, the press conference was cancelled in order that Mr Krueger could be examined by a doctor. Mr Krueger's health is stable and he is recovering well."
A BMW source added: "He's not been hospitalised, he was seen by a doctor immediately afterwards and effectively given the all-clear.
"He had undertaken a lot of travel immediately before this and had said he had been feeling slightly unwell before going on stage but insisted on going on with the press conference.
"He just suffered a severe bout of dizziness and immediately after was examined and found to be fine. He's not in hospital but I think he has left the show and doesn't plan to return today."
Chief financial officer Friedrich Eichiner took over the press roundtable that was held afterwards.
The IAA auto show opened on Tuesday for a press tour. Alongside Volkswagen and Daimler, BMW has a prime place in the huge exhibition with more than 1,000 exhibitors.
In early trade in Frankfurt, BMW shares were up 1.03pc to 86.22 euros.
