Red Bull was able to establish a new pitstop record during the 2013 Malaysian Grand Prix.
The previous record belonged to McLaren as last year they were able to change all four tires in 2.31 seconds. However, at the Malaysian Grand Prix the record was improved no less than six times, with five of them belonging to Red Bull. One of those achievements happened during Sebastian Vettel's first stop when the pit crew did their job in 2.13 seconds.
The other four occurred during Mark Webber's pitstops, including the one in lap 19 when Red Bull's mechanics replaced the used rubbers in an almost unbelievable 2.05 seconds, thus establishing a new world record.
