Jean-Eric Vergne has been given a 10-place grid penalty for an unsafe release in FP2, while Toro Rosso has been given a €30,000 fine.
The Frenchman lost a rear wheel immediately after leaving the pits towards the end of FP2.
The FIA said: “This is regarded as a serious offense and the stewards are of the opinion that this was a significant breach of the safety requirements.”
The team will also have to prove that it is compliant with Article 14.7 of the technical regulations, which reads: “All cars, whilst under their own power, must be fitted with devices which will retain the wheel fastener in the event of it coming loose.”
The FIA technical delegate also has to check that all other cars are also compliant.Formula 1, Jean-Eric Vergne, Toro Rosso
