Both Vandoorne and team-mate Jean-Eric Vergne were forced to start Saturday's race from the pitlane when DS Penske was found guilty of gaining a "huge and unfair advantage", according to a stewards' bulletin, from having RFID scanning equipment in the pitlane.
An initial version of the bulletin said that the team had been using this to obtain information on what tyres its rivals were running, but a revised version removed the reference to tyres, simply stating that the team had been able to "collect live data from all cars".
