Porsche said on Friday (Sep 9) it and Red Bull were terminating talks about the possibility of Porsche's entry into Formula One.
"The two companies have now jointly come to the conclusion that these talks will no longer be continued," Porsche said in a statement.
Volkswagen's former chief Herbert Diess said in May that Porsche and Audi would join Formula One, which has so far been dominated by the carmaker's German rival Mercedes-Benz .
Media reports had suggested long-standing talks between Porsche and Red Bull were stalling due to a gap between how much control the Volkswagen-owned marque wanted and what Red Bull was prepared to give.
Red Bull principal Christian Horner ruled out a Porsche takeover last Friday and said any partnership would have to be on the Formula One team's terms.
Volkswagen-owned Audi announced in August it will build an engine in Germany and enter in 2026 with an existing team, likely to be Sauber, and the sport has been waiting for Porsche's move. REUTERS
