After the second free practice session:
Car number 04 was weighed.
An asymmetric and symmetric front wing deflection test was carried on car numbers 01 and 24.
A front wing flap deflection test was carried on car numbers 01 and 24.
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 IVT temperatures were checked on all cars.
The ES state of charge on-track limits were checked on all cars.
The lap energy release and recovery limits were checked on all cars.
The MGU-K power limits were checked on all cars.
The maximum MGU-K speed was checked on all cars.

The torque control was checked on all cars.
The rear brakes pressure control was checked on car numbers 01, 11, 16, 55, 44, 31 and 04.
The tyres used by all drivers during the sessions today have been checked.
A fuel sample was taken from car number 22.
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 22.
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.
