The tyre starting pressures of all cars during the race were checked. The tyres used by all drivers during the race today have been checked. A fuel sample was taken from car number 22. The fuel samples have been checked for density and analysed by gas chromatography. The results of all the fuel analyses show that the fuels were the same as ones, which had been approved for use by the relevant competitors prior to the Competition. Further the density change of the fuel samples taken today was within the permitted limits.

An engine oil sample was taken from car number 55.

The engine oil samples have been analysed by FTIR spectroscopy and viscometry. The results of the FTIR analyses show that the sampled oils were consistent with reference engine oil samples which had been approved for use by the relevant competitors prior to the Competition.

All car weights and the items checked were found to be in conformity with the 2024 FIA Formula One Technical Regulations.
