Will Red Bull struggle in Belgium?
In addition to their grid penalties, Red Bull have breached the FIA’s curfew rules on Friday at Spa.
According to the Technical Delegate’s report, members of the team who were associated with the operation of the car ‘were within the confines of the circuit during the eleven and a half (11.5) hour period which commenced at 22:00 on 26 July.
This is ‘fourteen and a half (14.5) hours before the scheduled start time of P3 and ends three (3) hours before the scheduled start time of P3 at 09:30 on 27 July.’
According to Sky Sports' Ted Kravitz: "The mechanics were making precautionary measures to perform some checks they wanted to run."
Whilst the Red Bull team did break curfew, no further action was taken on the team, as the rule can be broken twice in one season before they are given a punishment.
