The FIA has revealed that Max Verstappen will be using a new Red Bull Racing RB15 chassis for the remainder of the Australian Grand Prix weekend.
The Milton Keynes-based outfit submitted its scrutineering form to FIA technical delegate Jo Bauer for approval, but no conformity issues are expected.
Red Bull did not specify the reasons for the chassis change, but it is believed that a fuel-tank issue was the reason for the swap, as building up a new car is a faster process than replacing the tank itself.
Verstappen concluded Saturday morning’s FP3 session in P9.
The governing body also announced that the has team had used the first of its two authorized curfew jokers, with the US outfit’s crews working through the night on Romain Grosjean’s car to repair an oil leak.
