Technical Delegate's Report Before the Race: A front floor deflection test was carried on car numbers 01, 12 and 44.
The front wing of car number 23 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 2026 Formula 1 Technical Regulations. The front wing flap adjustable range of car number 23 was digitally checked. Clutch paddle linearity checks have been carried out on car number 44, 87 and 27. A fuel sample was taken from car numbers 14, 81 and 87. An engine oil sample was taken from car numbers 14 and 87. On the grid it was checked that all cars had fitted their tyres and the tyre heating blankets were disconnected, 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, 63, 03, 30, 16, 44, 23, 41, 05 and 10. On the grid the minimum tyre starting pressure of the LHS and RHS front and rear tyre was checked on all cars.

A physical oil consumption check was carried out on car number 81. The fuel pressure of all cars was checked. The logged pressure within the engine cooling system was checked on all cars. The engine high rev limit bands were checked on all cars. Fuel flow meter calibration checksums were checked on all cars. The instantaneous fuel energy flow of all cars was checked. The partial load fuel energy flow of all cars was checked. The fuel temperature of all cars was checked. The plenum temperature was checked on all cars.
The engine intake air pressure of all cars was checked. The maximum turbocharger speed was checked on all cars. The PU and MGU-K power reduction rates were checked on all cars. The DC sensor temperatures were checked on all cars. The on-track ES state of charge was checked on all cars. The ES state of charge on-track limits were checked on all cars. The ERS recharge limits were checked on all cars. The maximum MGU-K power limits were checked on all cars. The maximum MGU-K speed was checked on all cars. The MGU-K use at the Race start was checked on all cars. The session type has been confirmed for all cars. Chassis FIA checksum was checked on all cars taking part in the race. The torque coordinator demands were checked on all cars. The torque control was checked on all cars. The rear brakes pressure control was checked on cars 12, 03, 16, 41, 31, 27 and 10. The steering wheel of all cars has been checked. The Race start data of all cars have been checked. Single clutch paddle use for the Race start has been checked on all cars. It was checked that no classified car exceeded 80 km/h when leaving the formation grid prior to the start of the race. The maximum front wing adjuster system transition time was checked on all cars. The maximum rear wing adjuster system transition time was checked on all cars. The tyre starting pressures of all cars during the race were checked. Cold tyre pressures were checked on car number 27. The tyres used by all drivers during the race have been checked. A fuel sample was taken from car numbers 12 and 41. All the fuel samples have been checked for density and analysed by gas chromatography. The results of 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 X12. 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.
