From The FIA Formula 1 Technical Delegate To The Stewards Document 43 Date 05 June 2026 Time 20:23 The fuel temperature of all cars was checked. The plenum temperature of all cars was checked. The engine intake air pressure of all cars was checked. After the second free practice session: Car number 44 was weighed. The fuel pressure of all cars during the second free practice session was checked. The logged pressure within the engine cooling system during the second free practice session was checked on all cars. The maximum turbocharger speed was 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 torque coordinator demands were checked on all cars. The torque control was checked on all cars. Chassis FIA checksum was checked on all cars. The rear brakes pressure control was checked on all cars. The custom software versions were checked on all cars. The SECU software versions were checked on all cars. The tyres used by all drivers during the sessions today have been checked. A fuel sample was taken from car number 41 . 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 41. 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 the above items were found to be in conformity with the 2026 FIA Formula One Technical Regulations. The FIA Formula 1 Technical Delegate Manuel Leal
