There is a lot of discussion online about McLaren's lack of tire degradation in extreme heating conditions. Red Bull, it seems, has had an unofficial protest after Miami and caused the FIA to take a closer look. But there has been no official report.
Some believe that McLaren may have figured out how to use advanced adaptive materials to create a breakthrough in cooling their brakes and helping prevent their tires from overheating.

Others believe that McLaren has had an innovative breakthrough in cooling its brakes. The innovation would not be against the rules (yet). So, the race would be for other teams to figure it out and copy it, or the FIA would create a rule against it.

The inability of rival teams to fully understand what McLaren is doing has prompted some to question whether it may be operating in a grey area of the regulations.
It is understood that thermal images Red Bull had obtained from an outside party, which revealed some intriguing cold spots on the McLaren rear brake drums, had been shown to the FIA as part of an ongoing dialogue on the matter.
But despite repeated chatter on the matter, and even some suggestions that McLaren had been forced to change its design, the squad insisted that there was nothing untoward happening.
