Earlier it emerged the FIA was investigating two teams, believed to be Red Bull and Aston Martin, with Wolff describing it as an “open secret” in the paddock. He said there was “one team in minor breach, which is more procedural, and another team that is fundamentally, massively over”. “The submissions between the team and the FIA is confidential,” he said. Horner had insisted he believes his team were within the budget cap set at $145m last year after Wolff had emphasised how serious he believed a breach to be. “It’s heavyweight, it massively heavyweight,” Wolff said. The FIA will not comment while it makes its assessment, with the conclusions on the teams’ cost submissions expected on Wednesday. Horner was adamant he was willing to take action against the comments from rival teams.
