Brackley-based Mercedes are appearing at a tribunal over a controversial tyre test.
The team insist that they gained no benefit from the Pirelli test as the data was for the sole consumption of the tyre manufacturer.
Mark Howard QC, for the FIA, said telemetry data was transmitted back to Mercedes engineers and that they could not help but benefit.
"Running the car for three days at least informed Mercedes that they did not need to change the cars. That in itself would be valuable information.It is not beyond the bounds of possibility that some defect would have become apparent in the three days track testing, and it cannot seriously be suggested that Mercedes would not seek to remedy that defect.We would suggest that it is difficult to say Mercedes obtained no benefit from the test.
