Before the race:
The front wing of car number 10 was digitally scanned and the scanned data were compared with the
team declared CAD drawings. Further the team declared CAD drawings were also compared with previously submitted versions and checked for conformance with the 2023 Formula One Technical Regulations. The uppermost rear wing element adjustable positions were checked on car numbers 11, 10 and 27.
The minimum distance between the adjacent rear wing sections at any longitudinal vertical plane was
checked on car numbers 11, 10 and 27. A front floor deflection test was carried on car numbers 01 and 14.
The inclination, the diameter and the position of the last 150mm of the exhaust tailpipes were
checked on car numbers 01, 81, 14 and 02. A fuel sample was taken from car numbers 01, 44 and 21 and analysed during the race.
An engine oil sample was taken from car numbers 44 and 21. On the grid it was checked that all cars had fitted their tyres when the "5-Minutes" signal was given.
On the grid the temperature of the LHS and RHS front and rear tyre was checked on car numbers
01, 11, 16, 55, 63, 44, 31, 81, 04, 24, 18, 14, 27, 22, 23 and 02. On the grid the minimum tyre starting pressure of the LHS and RHS front and rear tyre was checked
on all cars. After the race: From The FIA Formula One Technical Delegate

The tyres used by all drivers during the race today have been checked.
Fuel flow meter calibration checksums were checked on all cars.
The instantaneous fuel mass flow of all carswas checked.
The fuel temperature of all cars was checked.
A fuel sample was taken from car number 20.
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 01.
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.
