I found it. It was Lewis and it was last year. I am still curious if the rule covering stopping on track and the litre of fuel for testing are different between qualifying and the race. Anyone?
The only snag is that after his super-quick lap, he was told to stop the car out on track, which he duly did. The rules state that all cars must return to the parc ferme after qualifying – the rule’s there so that the FIA can ensure legality of the cars and what not. The only acceptable circumstances are where the car is technically unable to make it back to the pits under its own power. Whatever the situation, the car must have enough fuel left in it to make it back to the pits and also the litre sample remaining too, required for checking the fuel compound.
Hamilton’s car was found to not have enough fuel left in it – this rule was put in place to stop teams running cars too light to give them more speed, but meaning they have to stop out on track – a huge nightmare for Lewis who now, throughout no fault of his own has to start from the back of the grid for the Grand Prix.
