The Woking-based outfit is introducing a major update to its car for this weekend's race at the Circuit de Catalunya as it bids to get its season back on track.
With the team working late to ensure the car was ready in time, personnel from McLaren were inside the confines of the circuit between the curfew hours of 11pm on Thursday night and 7am on Friday morning.
Each team is allowed two curfew 'jokers' during the season, before any sanction is handed down for a rules infringement.
