Seven of Ferrari's Formula 1 rivals have said they are "surprised and shocked" by the FIA's recent investigation into the Scuderia's 2019 power unit and want full disclosure on the matter. 

On Friday, the FIA released a statement saying it had reached a "settlement" with Ferrari following a technical investigation into its power unit, amid suspicion from rivals after the Italian outfit made significant gains with its engine following the summer break. 

In response to the FIA, Mercedes, Red Bull, McLaren, Renault, Racing Point, AlphaTauri and Williams released the following joint-statement: 

"We, the undersigned teams, were surprised and shocked by the FIA’s statement of Friday 28 February regarding the conclusion of its investigation into the Scuderia Ferrari Formula 1 Power Unit.

"An international sporting regulator has the responsibility to act with the highest standards of governance, integrity and transparency.

"After months of investigations that were undertaken by the FIA only following queries raised by other teams, we strongly object to the FIA reaching a confidential settlement agreement with Ferrari to conclude this matter.

"Therefore, we hereby state publicly our shared commitment to pursue full and proper disclosure in this matter, to ensure that our sport treats all competitors fairly and equally. We do so on behalf of the fans, the participants and the stakeholders of Formula 1.

In addition, we reserve our rights to seek legal redress, within the FIA’s due process and before the competent courts."
