Components - Article C3.11.7 The fuel pressure of all cars during the qualifying session was checked. The logged pressure within the engine cooling system during the qualifying session 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 car numbers 81, 01, 63, 12, 03, 06, 16, 44, 23, 55, 41, 30, 18, 14, 31, 87, 27, 10, 43, 11 and 77 was checked. The maximum turbocharger speed was checked on all cars. The PU and MGU-K power reduction rates were checked all cars. The DC sensor temperatures were checked on all cars. The on-track ES state of charge was 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 session type has been confirmed for all cars. Chassis FIA checksum was checked on all cars taking part in the Sprint. The rear brakes pressure control was checked on all cars. The brake temperature warnings were checked on all cars. The steering wheel of all cars has been checked. The Sprint start data of all cars have been checked. Single clutch paddle use for the Sprint start has been checked on all cars. It was checked that no car exceeded 80 km/h when leaving the formation grid prior to the start of the Sprint. The tyre starting pressures of all cars during the Sprint were checked. The tyres used by all drivers during the Sprint today have been checked. A fuel sample was taken from car numbers 06 and 14. 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. 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 2026 FIA Formula One Technical Regulations. The FIA Formula 1 Technical Delegate Jo Bauer
