Red Bull has ended its seven-year partnership with Formula One team Sauber. The energy drink company sold its majority stake to Peter Sauber who will sell it on to team sponsor Credit Suisse. The stake has been valued at 70m Swiss francs (US$42.2m). Although Red Bull has now sold its stake, Reuters news service said there was still a possibility Red Bull could continue as a sponsor of the team. Red Bull has now linked up with rival motor team Arrows, but Peter Sauber said negotiations with Red Bull boss Dieter Mateschitz were continuing.
