Scott Speed's season was disappointing. He had equipment breakdowns and several crashes. He spun off the circuit in wet conditions at the European Grand Prix. That turned out to be his last race for the team. After the race, it was reported that he was involved in a physical altercation with team principal Franz Tost. Tost has since denied this. Speed also said that they wanted to get rid of both him and Liuzzi. Before the next race at Hungary, the team announced that he had been replaced by Sebastian Vettel.
