Ferrari has revealed that it used a "dummy" radio message to trick Red Bull into putting Sergio Perez on to a two-stop strategy at Formula 1’s Abu Dhabi Grand Prix.
Red Bull appearing to have a bit more pace, Ferrari knew that its only chance of getting Leclerc in front was through strategy – and that meant forcing Perez on to a two-stop.
That opportunity came on lap 33, when Ferrari gave the impression that it was going to gun for an undercut on Perez to try to get Leclerc ahead.
It told the Monegasque driver: "Box opposite Red Bull."
However, the message was not real as Leclerc was long committed to a one-stop, and Ferrari was using the call to only make it look like it was going for a two-stop.
The trickery worked as Red Bull responded and pulled Perez into the pits immediately to cover off Ferrari.
Red Bull team boss Christian Horner admitted after the race that a combination of Perez’s tyre condition plus it seeing that "Ferrari were gearing up for an undercut" was behind its decision to stop the Mexican.
With Leclerc having no intention of stopping, that meant Perez had to recover all the ground lost with the tyre change, which he ultimately failed to do, as he finished 1.3 seconds behind his Ferrari rival.
Like it, well played Ferrari
